This is a project that has been sat on for quite a while. It was purchased 3 years ago with 280k miles, A blown engine, and rotted out floors and rockers. When I was 16 I stripped the whole interior, cut the rot out of the rockers, put all the parts I need in random places and then just lost interest in it for a while. fast forward 2 years and I finally get the motivation to work on it again so I don’t have to daily the 60k mile survivor MJ in the New England salt land. The engine came out of 2001 XJ That rolled over and was then purchased by my dad in 2003 to be used as a parts truck for his MJ. The 01 Motor sat under a bench for 19 years and fired right up and runs great with a little seafoam in the oil to clean things up. The transmission and t-case came out of my dads old 98 2dr that rotted apart on us and got cut into pieces by us. Rip 98 2dr the rest is being saved for a future trailer build Old engine out The one ton crane from harbor freight doesn’t lift high enough to get the engine+trans out with the header in place New engine in

Hello, my 1989 jeep Comanche long bed that I have, has been dealing with some drum issues going through inspection. I bought the jeep and and it already had what looked to be new shoes around 4 to 5mm of meat on both sides. The drums although I would say have seen better days. My question is, could I sand down the shoes really well and slap a new drum on?(its a Dana 35 rear too I should add). I have heard mixed things on throwing a new drum on somewhat used shoes. Should I give it a shot?

Hello everyone, I have 1989 jeep mj 4.0. I have been having issues with a draw on my jeep and finally did a draw test. Found my power latch relay is staying on far too long and is drawing about 1 amp at all times. What does this relay do and how do I fix this issue. THANKS!!!

Hey so its been a while since Ive posted on here but I got rid of my TJ about 2 months ago to free up some funds and a month later got an XJ. Its a '95 Country with the 4.0 Auto and the girlfriend has named him Eugene. Well here's the day I picked it up. and this is the interior It had but this isn't my picture. Since I got it I have had a good bit of work on my hands. I went to OBX beginning of the month and knew I wanted to bring it so I had to beat the clock. With that in mind I had the Jeep Shop throw a 3" Skyjacker lift on for me to save time, not to mention I couldn't really do it at my townhouse easily, and then I got to work on my days off. I mounted 31" Extreme Countries, new front pads, rotors, and a caliper, new exhaust manifold (which I now have to redo because the gasket it came with leaks now), Tow hitch, trim off the front lip, add cup holders and prolly some little stuff I forget. While we were down there the hurricane hit and I ended up being the only one in my family who could leave the house. I had it up to the doors in water..... Now that Ive been back I took off the roof lights and mounted a light bar, had the interior hydro dipped, and fixed the wiring for the cargo light. Hopefully within the next couple weeks I'm going to be adding a lund visor, front D rings mounts, and extending the roof rack with some rear lights. Also have to do front axle seals so I'm gonna throw an aussie locker in while its apart. Couple other plans for the winter is new floorboards up front, frame stiffeners, mount a rotopak where the stock spare was, Sway bar disconnects and YJ brake lines, and eventually an 8.25 with an LSD. Basically the plan for this jeep is be an awesome DD that can handle the roughest winter or dirt road I can find. I will be wheeling it but its not going to be a hardcore crawler by any means.

Personal Introduction: My name is Britton and I am an addict...jk but seriously though haha. Career wise I am a mechanical engineer but I prefer to consider myself a jack of many trades and a master of none. I am constantly tinkering on something, working any number of projects, and tossing ideas around in my head constantly (both a blessing a curse). Anyways, I've been into Jeeps since I could drive and this is officially the 4th Jeep I have owned. 1999 2 door XJ 5 speed, 4.0L, 3.5" lift, 265/75/16 BFG ATs on TJ Rubicon wheels, overhead console, cruise control. She was a street queen and truly hated to see it go. Especially since it was my first car with a lot of memories. 1999 XJ 4 door, 4.5" lift, 33x12.5x15 Federal MTs, doorless mod, bedliner floors and headliner. Nothing special made for the woods but not a true beater and I still took care of it Sold both and bought a stock 2005 TJ/LJ Unlimited 6 speed with 78,000 miles. Installed 2.5" suspension lift, 1.25" body lift, 305/70/17 Goodyear MTR/K on JK Moab wheels. Kept it otherwise stock and clean because I started to venture away from tearing things up off-road and prefer mild trail riding and camping now. Then I stumbled into this project...1989 Jeep Comanche MJ. Drivetrain and dash were swapped but not finished and virtually rust free with 4/5 star floor boards compared to a lot of other Comanches. The back story: December 2018: Me: "Dude look at this Comanche! Its half way converted, you think I should buy it?" Friend: "Do it! You always said you wanted to build one. It'll be fun." It is not fun. Well sometimes it was but never again will I take on a project like this. It might just be the straw that broke the camels back. Still undecided... I have a bad habit of getting started on a task and becoming completely focused on completing it then forgetting to take before and after pictures. I usually remember about halfway through that I should've taken before pictures so I apologize in advance and I'll try to explain each picture/process in detail to give the full picture. As bought condition 12/1/18 (Previous owners shop, but wish it was mine): Build Plans: -Full 2000 XJ swap interior, exterior, and drivetrain -Dual gas tanks ~40+ gallons (TJ gas tank behind axle and Dakota gas tank in stock location) -Metallic silver paint -Ford 8.8 rear axle -4.10 gears -Spring over rear -4.5" Rubicon Express front coils (possible spacer to level out) -Rubicon Express control arm drop brackets -JKS Quick Diconnects -ZJ V8 tie rod and draglink -Ten Factory Dana 30 axle seals -JL Rubicon wheels with 285/75/17 BFG KO3s -1.5" wheel spacer adapters (5x4.5 to 5x5) -Rancho 9000XL adjustable shocks -WJ control arms -Raptor Liner or LineX bedliner -Custom bed rack -Custom bed rails Teaser shot of the current status as of 9/29/19: I will be posting a full start to finish timeline/explanation/how-to of the build in the days to come to walk everyone through the long process this has been. So stay tuned for that. As of right now (10/10/19) it is currently my daily driver while the LJ is being worked on. Here is a list of things I still need to do on the MJ to make it "100% finished": -Bedliner (probably Raptor Liner) -Restore tailights (maybe LED bulb swap) -Modify and install overhead console (shorten, graft, LED bulbs, and determining mounting) -Reupholster visors to match new headliner, LED bulbs, and install (matching material was provided with it) -Install tailgate (at sand blasting 10/8/19) -Install Dirtbound Manta Ray rear bumper (ordered on 10/7/19) -Replace clock spring (possible WJ steering wheel swap at the same time) -Mount/Install emergency brakes with 8.8 adapter clevis -Fender flares (Very undecided on this. Napier or Notch or just stock trimmed with rubber edging) -Front bumper (JCR Crusader or Dirtbound Mojave. Really like the thought of a hidden winch front bumper and hope these could be modified for that) -Gear swap to 4.10 (front Dana 30 is 3.55 and rear 8.8 is 4.10 so 2WD until then)

So first, lemme preface this by saying that i have always wanted to build a 97+ converted MJ, in fact i have spent a few years researching the swap and i finally had things lined up to do the swap, including 2001 XJ and an 89 MJ... But life happened and i had to relocated from Florida to Kansas. I had spent several months using a website the searches all of craigslist looking for something interesting to pick up when i came across this. It was 1,000 miles away in New Mexico, made the 26 hour drive in 30. A built Comanche that had been converted to the 99 XJ drivetrain with a 2001 XJ Limited interior. Literally my dream swap. I believe that the 99' is is the best year of the 4.0. So these are the specs the day i bought her: ****Motor**** - Freshly rebuilt 99 4.0 bore over .30 - Bored throttle body - High Volume Melling oil pump - Eddlebrock duel outlet header - High flow intake manifold - Brown Dog motor mounts - IranMan4x4 Brackets ****Drivetrain**** -AX15 5 speed with a new clutch - Np231 transfer case with Chevy HD widechain and gears - 6 pinion planetary ****Suspension**** - 6.5 inch lift - SOA in rear - Spartan lockers - 3.55 gears - 29 spline shafts - Terra Flex high steer - Rubicon Express lower arms - Adjustable Rough Country upper arms - Rubicon Express double sheer track bar - BDS Shocks ****Exterior**** - Loans Metal Products front bumper - Warn 9.5ti winch - 4 LED Pod lights - Bushwacker fender flares ****Interior**** - Interior from a 1999 XJ limited - Heated leather power adjustable seats from a 2001 XJ - Wood grain interior - Correct two window switch installed Some pictures from the day i bought her: Things I have done since having her: - Fox 2.0 shocks up front - Fox 2.0 Steering stabilizer - Rebuilt the winch by replacing the solenoids and cleaning and re-greasing the gears - Reqired the LED lights so they are not a fire hazard and work with the factory fog light switch - Installed a WJ Overland wooden steering wheel with radio controls - Installed IronMan4x4 steering box brace with sector shaft support - IronMan4x4 Steering box bracket / spacer - Rough Country Floor mats - Spooled up some synthetic winch line Here are some pictures of what i have done since having her: And this is what I am currently in the process of doing (I have the parts ready to install): - Installing my OR-Fab bumper and warn M8000-S winch with Rigid LED lights installed on the bumper (from my old 99 XJ) - Creating a new headboard with overhead speakers and the full length XJ limited overhead console - Installing the stock XJ Limited tweeters - Getting the steering wheel radio controls to work with a WJ clock spring Some of my long term plans: - Rear mounted winch - X-Max fender flares - Two tone gloss black and Rhino Line matte black - 4 link suspension - 4.7 stroker - Dana 44 front and rear - Creating a logic board to make my steering wheel radio controls be able to select between front or rear winch, then be able to winch out and in Thank you very much for viewing!! I hope it was worth your time and id love to hear some thoughts and ideas!

Need item #9 which is power antenna brace. found on XJ with power antenna behind fender

I’m trying to swap a 1992 XJ gauge cluster out a “country” package, into my 1988 MJ Pioneer. I can’t seem t find a proper wiring diagram for either of the models gauge cluster plugs and need some help. I have to use the XJ clusters plug so I need to splice it into the MJs wiring, any help would be greatly appreciated. Thanks

Photobucket ruined all versions of this build on the internet, and people have asked on other forums if I had the old pictures. I do, but it's a lot to sort though, so I've basically decided to post the build over from the beginning, just much more condensed than it was originally. I am going to upload everything to Imgur, so hopefully they don't pull a Photobucket at some point, but we could cross that bridge when the time comes. Since I was doing that anyways I figured I'd throw it in here, as it really takes no added effort and some of it is applicable to the MJ platform. The day I bought it: I had actually thought it was an SJ Cherokee based on the terrible ad and the owner's lack of helpfulness. Turns out it was an XJ, but for $100 I couldn't say no. It didn't run, but as it turned out it was just the ground cable off the battery. I should have sold it right there, pocketed the couple hundred in profit I could have made, and moved on. But nooooooooo. It honestly was terrible. Rust, disgusting interior, hack repairs... The piece of aluminum instead of a back window was a nice touch. Disgusting. Steering column was all torn up because of a NSS issue and really bad troubleshooting. Yeah.

Well I need some help figuring out how to wire these running lights... I have a 1990 mj that I am about 90% done with a 97 swap just basically buttoning up all the small issues now. I have the drive train and dash with harnesses out of a 2001 xj I left my mj rear harness and have been plugging wires figuring out what goes to what and have narrowed the majority of it all down I have my stop lights reverse lights brake lights and turn signals but for the life of me I can’t seem to figure out how to wire these damn running lights from the 2001 dash harness to the rear mj harness I wish now I would have just ran the xj harness back I feel as if it would have been less headache but yet here I am I know the mj “running lights” are the blue wire on the oval connecter and the br/YL wire coming off the xj dash harness is the equivalent to the xjs running lights but how is it supposed to be wired I tried running it off of the drivers and pass her sides but it just keeps popping fuses I need help! Pics of the truck where it started and where I’m at!

I know there are many threads that explain this procedure but another won't hurt from someone elses experience. So, this weekend I am starting the dual diaphragm conversion on my 1989 MJ. To start off, here are the tools and equipment I have so far: 1996 XJ Brake Booster and Master Cylinder (bought off of JC Whitney) $170 (2) 3/16 diameter bubble flared with 10mm fitting brake lines STANDARD flare tool (rented from auto parts store) (1) 12mm thread 3/16 diameter line, fitting (1) Vacuum Tool (4) 10mm stop or lock nuts (1) Line cutter The four 10mm nuts are for the brake booster. The other two bolts on the other side can use the nuts off of the stock MJ booster. I chose to buy the bubble flare lines because the 1996 MC takes bubble flare ends and not double flared. The MJ distribution valve body DOES take double flare though. So, I am going to have to flare one end of each line using the standard flare tool. Also, one of the ports on the 1996 MC takes a 12mm fitting which I will have to slide on the line before flaring again. 1996 XJ brake booster 1996 XJ master cylinder currently being bench bled using vacuum tool Vacuum tool This tool made the bleeding process a little easier. There are many ways to do it. Putting each of the hoses from both fittings into the bottle and pushing the rod in, will have the same effect. I did both methods just to be sure. That is where I am at right now. Tomorrow I will start the upgrade!! :wrench: Also there will be lots of more pictures! :clapping: :thumbsup:

Does anyone know if there is a write up on how to swap the newer +97 XJ front doors on to a MJ? I would like to know how involved it is before I go Buy the doors. Thanks

HI I am new to this community but not to Jeep forums. I tried being active on Cherokee Forum, but I decided to not spend too much on my XJ. I daily drive an XJ and used to want to build it up. However I have always loved the MJ platform and that was what I wanted in the first place. Well I officially got the title to a 1991 Jeep Comanche I bought at the end of January. So it is official and I can dump money in it and start a build thread. I bought it mainly for being a straight body with no rust. It will be a long project but hopefully done by the end of the year.

Looking for a 91,92, MJ/XJ crossbody harness, for PWR windows & PWR Door locks, harness needs to have the relays or the relay connectors installed on the harness. Good Shape, shoot me a picture, tell me a price, don't have a lot of salvage yards and no pick a parts in my area. THX

Hey guys new member here. Anyways I found something that might be interesting for local so cal people. Found a 85 xj turbo Diesel engine on cl for 1k. Idek if it's a good price. I feel like I could find a whole xj for that. But anyways if anyone has a diesel and needs parts or wants to swap there you go cuz I know there rare

Does anyone have a few of these laying around in good shape? I popped mine out to repaint the actually caps, and all but the last one came out without struggle. The last one shattered into several pieces... Typical. I'd like at least two in good shape. The one in the top, right has some of the chrome ring missing... Willing to pay some, but not looking to spend a bunch. They came from the center caps pictured below:

I am going to look at a XJ that is for sale. I talked with the owner and he can't afford to pay the mechanic to work on it anymore so he is cutting his losses and buying another car. He has owned it for 4 years and three weeks ago it started blowing fuel pump fuses. He kept replacing them and then it eventually quite blowing them. It still would not start so he took it to mechanic. The mechanic found motor oil in the PCM?? Ya weird he was baffled to because he said the engine has no major oil leaks. So they replaced it with a junkyard PCM and still no spark or fuel. They replaced CPS and still nothing. He said that's all he could afford and the mechanic said it maybe another sensor that is to blame. The mechanic has checked the wiring harness and found no issues with it. Any other sensor that would cause no fuel or spark? Any ideas or what to look for when I go to check it out?

i am looking to make a few bucks on the side by building parts for jeep mjs and xjs.. PM me or reply if you have anything you would like to have built and or would like to see being built. i may be willing to manufacture in small quantities if i get enough requests. thank you

I'm in search for solid vent/ wing windows for my jeep comanche. My current moveable vent/ wing windows leak. I'm willing to trade or sell my moveable windows for a solid. PM me if you are interested in helping me!

I got a 2000 XJ as my first car, I bought it from my neighbor who had served in the marines stationed on the Hawaiian islands. Three years later, after spending endless time, money, sweat, and blood on it. Someone rear-ended me, totaled the Jeep and bent the uni-frame out of shape. I had always liked comanches and cherokees, so I decided I would find an MJ to transfer my XJ's heart, soul, and skin on to. I found a 1989 Eliminator in Lake Havasu City, Arizona with 130,000 miles, rust free, and a clean title. It was too good to let go. After an 8 hour drive through a ton of desert and Las vegas at rush hour, in a Jeep held together by prayers, I finally had it home. Little did I know that this MJ had spent time in Hawaii too :thumbsup:

So, as some of you know, my MJ has a utility bed on it currently. Found out that it is partially welded to the frame, which is lame. Pics are in my build thread. I have a standard MJ bed on my project that I want to swap on, most likely. Or might even consider a flatbed of sorts. Anyways, for those of you who have done flat bed or other bed type swaps, what did you do for fuel tank mounting. I was thinking maybe just a couple pieces of steel running across the frame from side to side. Even if I swap a factory bed, I think it will make things easier overall. Thoughts, concerns, or constructive criticism? Thank you.

So its been done before but theres no clear guide that i can see that tells you what length cables you need for a handbrake setup compared to the foot brake. Anybody know a good match for a short bed?

Does anybody have any insight or experience removing the factory, integrated trailer hitch from an '88 XJ? It's the kind that bolts to the rear bumper, in addition to the frame rails (see below). I want to put a standard 2" Reese hitch and use a drop shank to accommodate my lift, but I'm kind of stumped on how to remove this one.

I'm located in FL and I'm looking for a MJ but can't find one. Any helped would be awesome. I checked the classifieds and nothing I'm willing to buy but I'd rather trade my xj. If anyone has anything you can text me at 352 817 6963 or email me at usafmikejr@live.com
