  1. Hi All, This is my first ever post on this forum or any forum for that matter. I have an 87 Comanche 4.0 pioneer that has a bad ticking noise. It has been doing this noise for the last 6 months I've owned the truck. I've run thicker weight oils, various additives and they did little to help. The noise is strange in that it is intermittent and only seems to get bad after the engine is fully warm. Did the rear main seal two months ago and didn't notice any metal debris in pan. It doesn't get noticably audible until oil pressure is under 40. Seems to be worse at idle(or just easier to hear) or when coming to a red light after driving at higher speeds. I have had two people listen to it and one believed it was most likely a bad lifter. The other seemed to think it was a possible exhaust issue. I believe that I do have some exhaust leak, but I don't think it could be the cause of metalic click noise. I am leaning toward it being the lifters, but I also know these engines can develop piston slap. Before I get into any fixes is there anything that can be done to help determine if the tick is a lifter, piston, or possible exhaust? What do you guys think it sounds like? I have attached a short clip of the engine ticking when fully warm. Thanks for any advice you may have. VID_20190522_091052028~3.mp4
  2. I'm looking to stop the heat coming off my floor in my MJ, I want it so that theres a layer of good reliable insulation, and then some vinyl/rubber material on top instead of carpet. Does anyone have any good suggestions? Not too worried about stopping sound, just heat.
  3. I'm looking for a replacement rear drive shaft for my 1988 MJ Long Bed. Looking for on that is 48.5 inches. U joint broke and dented old shaft when it fell off. I'm in Phoenix, AZ. Anyone know where I could find one?
  4. Hey everyone! Today I had quite the extravaganza! on my way to work today I had to stop at a stoplight on a very steep hill, when I went to take off I heard a loud pop in the rear end but didn't think much of it as I thought it was something shifting around in the bed, then I noticed that every time I let off the gas I heard and odd whine in the rear end, once I got to the job site I notice that their was some fluid on the front of the Dif where the driveshaft goes into it, again didn't think too much of it as I'm at work and have other things todo, on my way to the audio shop after work I grabbed some gear fluid and filled up the quite empty Dif, then proceeded to head over the hill to get my radio installed, the whole time over the hill every time I let off the gas and tried to decelerate or coast I heard this god awful whine grind sound from the rear end and it kinda vibrated, since I was on a small 2 lane road I had no decision but to drive on and just keep going faster and hope for hills to slow down, we got into San Jose and stopped at McDonalds to grab a quick burger, and as soon as I pulled out of the parking lot their was this loud clank and I had no power and could hear the driveshaft whipping around so I threw it in nuetral at a green light hopped out and tried to push but it seemed like the front axle was still in park so I hopped under to take a look and I saw that the driveshaft had slipped out of the diff with a spindle on it...... not sure if thats normal in any situation..... so I put it back in the diff and threw the truck in 4L and crawled it to the closest street where I found out my whole diff would rotate about 7 inches up and down past center when in gear and reverse so limped it to an auto zone 2 miles away and tightened the 8 19mm bolts on the U clamps holding the axle to the frame, it helped a lot with the rotation but maybe I needed to torque them more as I'm still hearing the awful sound from my rear end when I let off the gas and try to coast, does a driveshaft come off past the last U joint and with a spindle in any situation!? I think I'm screwed and need todo an axle swap this weekend ill update with pictures in the morning when I take a better look at everything but could anyone have an idea of WTH is going on here other than a blown diff....................
  5. Let me preface this with some backstory, I picked up an '86 i4, 2wd MJ for $400. It's rough, missing the bed, exhaust is all but gone, floorboards are shot, etc. I have no sentiment towards this Jeep, so I have no problem cutting it up to make this work. Furthermore, I have an opportunity to pickup an ENTIRE power-train (read: motor, trans, xfer) out of a 1980 K10 for FREE + shipping/gas to drive and get it. Were it not for these facts, I would not be even considering this project. Now that that's out of the way... As someone who has never swapped a motor before, what are some things I may not even think to research? How much cutting and firewall massaging am I looking forward to? Will it fit in my engine bay? (I think this is the short '86 that won't fit a 4.0). What are my options for motor/trans mounts? I'm sure there is a lot that goes into this that I haven't even considered, Who has pointers? And yes, I've used the search feature of not just this forum, but Google as well - I've bookmarked dozens of pages for this project.
  6. So I need some help. I'm helping my Grandson build his first MJ. We found a almost perfect 2WD minor rust ran great some standard issues like Steering column falling apart. We found a MJ 4x4 donor and did a 2wd to 4x4 swap and fixed the steering column. Now we have no power to the Fuel Pump. I know the Pump is good cause I can hot wire it. Ran a continuity check all the way back to the resistor block and the wiring is fine. also checked the relay and it seems fine. When we turn the key everything works but the fuel pump, If I hot wire the pump the truck runs. I can't figure out what we would have done that is not telling the relay to send power to the pump. I know and checked the connector and switch block on top of the steering column I haven't removed it yet cause everything works but the pump when we turn on the key. any ideas? Thanks in advance.
  7. I am a 14 year old that owns a mostly rust free 1989 Comanche short bed 4x4 5 speed 4.0. I would like to put a lift in it, but I have a limited budget. What do you recommend?
  8. I was told by somebody at a gas station that a Ford Ranger sport bed would fit on the short box Comanche. Could any one confirm that? I haven't seen anything about it in my searches. My bed is pretty rotted up on the sides. Should I look for a ranger bed or repair the sides? I don't have a big budget by any means. Lol. It needs the outer walls above the wheels and the inner wheel well on one side, maybe both. I was thinking for a repair that pop riveting or welding sheet metal bent/cut to shape on both sides would work nice. After cutting the rot out of course, and make them the same on both sides so it doesn't look absolutely terrible. Any thoughts?
  9. hi guys my name is Justen, i have a 1988 jeep comanche 4wd that doesnt have the original motor. i aint afraid to get dirty and tear it apart if i have to. the jeeps motor was swapped out in a day by the guy i bought it from it has a 2003 jeep wrangler 4 cylinder motor in it with an allison transmission, it wants to turn over but i can't get it to start at first it was the positive connectors that were loose i tighten back in and it works i had to jump the battery to get the motor to wanna turn over. i need someone with experience on what to do, i was thinking of finding another 03 wrangler and taking the motor out and just replacing the motor with that one would that be easier? any advice would help me, thank you.
  10. So last July I bought a house and as an incentive he was going to include his broken down 89 Comanche.(I was going to buy it regardless but I like small trucks always like the 4.0) Anyways what I got is a 89 2WD 4.0 Manual truck. I would like to get it up and running first and then maybe do a 4WD conversion and keep it a stick. I might do a slight 2-4 inch raise seeing as it'll be a trail/dump runner so need to keep it street legal. I have a little automotive experience but not much in the ways of axels/transmissions and such. I did it get where I can drive it. Had to replace bad starter and bad and wrong battery (probably what fried the starter). So it cranks every time now. I do have an issue on occasion with the transmission not wanting to go into gear opinions? Also I have a brake issue they work but the pedal is pretty much at the firewall and it isn't the quickest response. I tried bleeding them but no air bubbles and passenger front has a stripped bleeder screw that I will have to deal with as well. The brake fluid has not dropped so I don't think there is a leak but again not sure. Also runs a bit hot after shut off I heard this is common and only real way to fix is to convert to open system (already replaced tank, pump, and thermostat, helped a lot) Any help would be greatly appreciated also I will post pictures and video of it running as soon as I get home.
  11. Hey everyone! I'm new to this website and found it while looking for advice on fixing up my new(old) 1987 Comanche(if this isn't the right forum to put these questions on i'm sorry i didn't know :???: ), the previous owner hadn't run it in 6 years, and it spent the last 3 of those outside. it has minimal surface rust but the body was spray painted a vomity green, i plan on changing this in the future but at the moment its not important. my first goal is to get it street legal, the brakes and tires are being changed and i would like to clean out the entire engine bay as well as change all the fluids if i have the time. what i was wondering is if any of you guys think i should check anything else for possible safety hazards or any tips/tricks that could help when dealing with a Comanche, or any project car tips in general (This would be my first one and i'm very excited) also, how would you guys go about cleaning an oily and greasy engine bay/firewall without damaging any other components p.s. the Comanche runs, but a little poorly, hopefully refilling fluids and cleaning/replacing hoses will fix it any help or advice you could give would be great, Thanks a lot
  12. Recently acquired a 2004 chevy trailblazer it has 4.20L inline 6, locking rear end (g80), 4L60-E, and stock transfer case. It was t-boned passenger side impact,side runs and drives straight. What I am curious has anyone swapped these components(any or all) into their jeep comanche or cherokee and what were the problems that they encountered. I would definitely like to put the locking g80 rear end under the manche for sure, also the trailblazer's rear end is a coil sprung 5 link, which could be a huge upgrade. Swapping whole drive train would be most ideal, as the i6 is rated around 275 for both torque and horsepower. Thank you guys in advance for anything you might have to say to help or direct me to help.
  13. I've been looking to get a lift for my 1990 mj the only options I've seen is rough country rro and runic one express. Ive been thinking about the 4.5" rough country because I don't really wanna go spring over axle mainly because I don't have a good welder but I'm very disappointed with the lofts because they don't come with new leaf springs and the 4.5 rough country doesn't come with a track bar or drop pitman arm or quick disconnects. What are you guys running. Any good lift kits out there that you can't find easy? I have hers people using hell creek but I can't find a kit for the mj when I go to there website it just shows 1/2, 3/4 ton trucks or s10 any advice for a good lift would help me out a lot. Thank you
  14. I just picked up a 2wd 88 eliminator and id like to do a 4x4 conversion. What all will i need to do to accomplish this task? I believe all i will need will be a front axle trans and matching t-case all linage involved a bell housing and a front driveshaft. Now this is my plan: I'd like to do a Dana 30 with 4:10 gear ratio, a bell housing from a late 93+ Cherokee with the external slave, an AX15 trans with matching NP231 t-case 23 spline, a new center console to account for the 4x4 shifter lever, and a custom front driveshaft. Now am i able to keep my original rear axle or will i have to swap that as well, And if i can keep it how can i change it to make it work with the 4:10 gear ratio i'm seeking? Let me know if i'm missing or forgetting anything. I'm also looking to give it a 3"-4.5" lift. With that lift what size tire would ​you recommend? I'm thinking of running 35's. ​​ :driving:
  15. I need the longest one of the three. Despite my best efforts I manage to put it in the wrong hole and broke it trying to get it out. Shipping on 72687.
  16. So I plan on doing the 4wd conversion to my 1989 2wd automatic 4.0L MJ. I obviously want the cheapest route and don't mind the work needed. I guess my question is, if i found another xj within the years 87-90 (renix) does everything swap right in? besides the rear driveshaft (I know that would have to be re-sized). I also have an automatic tranny right now and keeping it would be less costly and less work than getting a manual trans but would my ax4 be a good match up for a transfer case? Or would I have to swap the trans from a donor with a 4x4 auto? This is my first big project for me so help would be appreciated! :thumbsup:
  17. I noticed a few days ago my brake lights have not been working for some reason. But I have taillights or running lights (whichever you prefer) and they are nice and bright. I have been over the sockets in the back before I had inspection a 6 months ago and cleaned them all up to make sure I was getting good connections. they worked really nice up until a few days ago. I only know they stopped working because I always check to make sure they work when I'm driving down the road. not sure why I do that but you never know what weird stuff happens in a Comanche. Anyway hopefully someone can point me in the right direction please. Thanks!
  18. Hey all I was wondering if someone could point me in the direction to find a Manual window regulator/ actuator for the passenger side of my 86 Comanche? I thought I heard that I could also use some parts from a cherokee up to 89, not sure if this is one of those parts. Thanks
  19. Hello all, I am new to the club and have been looking for a comanche for quite some time now. I have found one that is close and seems to be a good deal except for this picture the owner sent. The owner said the frame has no rust on it, but this looks like frame rust to me. I think its right in the middle under the cab, but as I have never owned a comanche before I do not know enough to make a decision on this. Is it fixable within reason if this really is the only rust? I do have an arc welder but do not know how big of a project this might be and I do not know how important these bars are. Any input is appreciated. I have not gone to see the truck in person yet.
  20. Does anyone have a part number for the plastic door lock Rod clip for a manual door ...passenger side. Apparently one off of a electric Cherokee door I got will not work. It's to fat so I whittled on it and then I broke it. I was hoping to find a dorman part number or something I can pickup at lock parts store.
  21. I have a 1990 chief , i am trying to add an Overhead console from a 1990 xj i have the console and the mounting brackets and the wiring from the donor vehicle , my problem is the wiring, I have not been able to find a write up for this, involving an MJ. have no problem having to modify the harness, and electrical work does not scare me. It does appear i do have the ambient sensor temp in the middle of my bumper. i would like ambient temp to work, as i do live in Texas. if someone could post a link or so or even pictures on how they did i would be very grateful.
  22. I just purchased my first jeep an well I drove it home guy said no leaks I looked there was none to the naked eye. As soon as I pull in to car port. Low an behold a leak so I crawl under an notice it seems to be coming from where the tranny mates with the motor. Any ideas on how to fix this asap. Since I bought this Lil truck to be my work truck.
  23. When i am on the highway, doing around 70, i get violent shaking from the front end of my truck, and the only way it goes away is if I reduce my speed to around 55. I have had this problem before and i have fixed it and now i am at a dead end. I have balanced the tires, and replaced the steering stabilizer shock. and it is still violently shaking at high speeds. I know it isn't warped rotors cause its not when I'm braking, and also it wouldn't be the wheel bearings because its a constant shaking in the steering too. This is the third time it has done this and i am getting really frustrated with this vehicle. Any advice would help!
  24. I am looking at buying an '88 Commanche and want to know what all I need to be looking out for when purchasing. What will I be doing with it? The plan is to build a street-able weekend warrior...something along the lines of 5" lift on 35s. I plan to wheel it. What I know about it from the ad and owner so far... It's a 4.0 and runs good 5 speed manual Body is in good shape with no rust spots (highly unlikely, but we'll see) 2 wheel drive Needs minor TLC - rip in seat and turn signals don't work...nothing major Now all of this of course needs to be confirmed, but what do y'all think so far? Is it a good base to start from you think? They're asking for $1,200. Any help in the matter would be appreciated!
  25. ok this is bothering me really bad and i need to know does anyone know what the support rail is on the floor of the comanche that runs right over top the frame rail? and if i can buy a new one please help
