Well I have already replaced U joint Hub Ball joints but it happens while not turning as well. thats why i was thinking maybe the drive train is bouncing. And i feel it in the floor almost like it is under me not in front like it would be if it were suspension

I do have 4wd. is there like a nipple that the line goes over? I did not see any when I was under there earlier today. I would like to hook them back up obviosly to keep dirt and moisture from getting in. I just changed the fluid and it looked to have a little water in it

Hey MJ lovers! So i have an 88 MJ 4.0 BA10 Trans When i am driving and I approach the top end of a gear i get this knocking that i can feel in what is left of the floor. I also get it when I turn a corner too fast. I suspected it was a loose exhaust hitting the front driveshaft u joint but alas it is tight. Now I am thinking maybe trans or engine mounts? The trans mount looks a bit old but not cracked dry rotted or missing. I havent investigated motor mounts. Does anyone have any thoughts on what else to look for? Also how can I go about checking the transmount and perhaps the engine mounts? Thanks. Ant

88 MJ 4.0 BA10 Trans Can anyone clue me into this Air Breather Junction above my starter? One runs down and I think is supposed to connect to the BA10 transmission as a breather line. Do you know where it hooks in? Also can you tell me what the other 3 lines are for? Weren't run to anything when i bought it. Thanks! This truck has soooo many air and vacuum lines. Where does one begin.. Thanks, Ant

Hey I know this is an older thread but for future readers here is what I did. Took 10 mins. When the handle comes off in your hand don't fret. Grab 2 pairs of vice grips, a razor blade, a pair of diagonal cutters and a pair of pliers. Cut back the black vinyl covering about 3 inches. The outside protective cable is a twisted strand cable. lightly grab towards the back with a pair of vice grips. Leave an inch gap or so and grab the front with another pair. Twist in opposite directions which will birdcage the wires. Snip the individual strands with diagonal cutters exposing the inner cable. Pull on cable with pliers to release hood. Your done! and you didn't have to take anything apart. no cutting into the hood. No reaching up under the truck. Hope this is useful to someone

Ok Thanks. Ill try cleaning it really well once i get the stripped torx out. Why?!! Just Why? will be replacing with a hex bolt

Hey Guys! The cold here in Philadelphia has delayed my work on my 88 Comanche project, 4.0 5speed. I got the slave cylinder put in and the transmission back in about 2 months back and figured why not try to start her up. I bought the truck not running and it hadn't run in 3 years. Well not surprising, didn't start. Cleaned all the ground, and electrical contacts. No dice. Everything having to do with ignition looked brand new, obviously someone had tried to start her before. What the missed? Crank position sensor. Put a new one in and tried to start her up. She lives again!!! Cranked up on 3rd try. She is running rough and over revved to 3000rpm but i am not all surprised. Its been a while since anybody loved her. Probably will need a new IAC. Any other thoughts on the high rpm? My next task is to fix the throttle body. The spring does not release. if i hit the gas it will stay in position. Tried soaking with pb blaster, didn't seem to help. My question is should I rebuild it? How do I rebuild it? does anyone know where to buy a new one. Only ones I have found thus far are not Renix compatible. I would almost rather replace than rebuild but if i cannot find one, that is not an option. Any input would be much appreciated. Thanks in Advance, Ant

Thanks that was very helpful. I found out my resistance issue was related to the switch but something is still whacky in the column. Time to open it back up and take another look

Also if anyone is savvy to ignition issues, I started a thread pertaining to mine.

A-Ha! Much obliged! DirtyComanche/Green Mesa XJ. That is just what I needed. Now that I know what that is called (CAD) i can further research what to do with it. Thanks As far as the other lines that makes sense and all lines accounted for. They are all cut, except fuel lines thankfully, so i need to bend/flare new lines. Now that I know what they go to, it should make it much easier. Green Mesa: Yeah I'm not real sure how the 4wd selector gets reattached to the transmission. I figured worse comes to it, I will take a ride over to where the xj is and take a look at how it is hooked up. I see the arm/actuator, I'm just not sure where/how it bolts up. Sorry to hear about your hurricane troubles. Hope everything remains reasonably dry and intact.

Ignition Cylinder Problem: So when I bought my 88 MJ, the ignition was stuck in the on position. Truck came with a new cylinder, so I had a guy put it in for me. Problems: 1. After getting the ignition installed and the steering column mostly installed, the key became stuck in the off position. It would release but not move forward. He took it all apart again. Got it moving, put column back together. I moved the key into on position and then off, and now I got the ignition stuck in off position again. 2. The ignition seems to have no resistance in the start position. no spring to it. It feels as though it is just like turning key to on position. No spring feel from start to on. Now I do not have a battery in the truck, and have not made an attempt to start the vehicle since I bought it. Its not quite ready, Electrical fixes needed. But I will be making this attempt soon and I really need to solve this lock cylinder issue. Any ideas thoughts? Always appreciated, Ant

Green Mesa xj: Damn torx bolts! Anyway, I got the transmission out and replaced the slave cylinder and after a few hours of work, got it back in. there are two valves on top of the trans. one of which has xfercase fluid in it. the other is some sort of breather hose. Can anyone tell me where these lines are supposed to connect? The plastic one (breather) went into a fuel/vacuum line, and then into junction piece wich was not attached to anything. The transfew case line was not attached to anything so I also have no idea what that goes to. See Picture: ALSO THIS? Don't know what it is for? its on the driver side of trans. Maybe for 4 wheel drive selector? Also if anyone can tell me how to reinstall 4WD that would be awesome. I didn't take it apart so I have little idea of how exactly it is supposed to go back together. I see the lever and actuator but I don't know how to rebolt. More Questions: Driver Side: Brake lines have been cut and partially removed so I can't follow them all to source. One of the top lines runs to some valve on gas lines. The other disappears up above fuel tank. Any ideas? Passenger side: These lines are running on passenger side by the front axle. They hook into that connector which appears like some sort of vacuum line? Not sure what they are for. Any help would be appreciated. Since I bought the truck with some things already apart, I just don't know where they go to replace. Brake(?) lines I want to replace because they are old rotted and broken/cut but again can't say where they are all supposed to go. Thanks, Ant

All bolts that attach bell housing to engine are removed. I can't get the trans mount that is attached to the crewmember off so I unbolted the crossmember. Trans will still not come out. Its bolted to something I suppose. Any ideas what could be holding this up? When I let the jack down it drops enough for crossmember to clear the bolts and then stops. I cannot figure what is holding it in

Great write up. Thanks. Considering doing a Peugeot to ax15 swap. The ax15vis out of a 92 jeep Cherokee and going into an 88 Comanche. Looks like all I need parts wise is the pilot bearing from a 74 cj?

I confirmed that it is a Peugeot trans. 87MJTIM: Thanks for the write up. It seems simple enough. So the only thing I need to change is the pilot bearing to a 74 cj? And of course the ax15 parts and pieces. But I have a complete 92 xj 5 speed to pull from. SteveO: that is sweet man. I can't wait to have that feeling. Mine was actually sold as an 87 but according to the title and stickers under the hood it is an 88

87MJTIM: Thank for that manual. I'm sure I will need it. There are electrical problems already that I can visually see, and I haven't even put a battery in it yet. And yes there is a reservoir on the passenger side towards the firewall. The small hose that comes out of the thermostat housing splits towards the firewall, Then goes to the reservoir and to that vacuum line that passes into the firewall. Green Mesa: Yes I do have the ax15 trans in the other jeep but i am really nervous about doing the swap because i have read about the pilot bearing and input shaft being different and I havent found a lot of information as to exactly what parts i would need to put a 92 ax15 in an 88 comanche. I don't want to get that far into a project that I know very little about. Maybe dropping this transmission will at least give me some idea as to how these things all connect. I think I just need to see it. I know it seems a little silly to put the Puegeot back together if I want to do the swap anyway, but I would feel more comfortable if i could get the truck back up running and driving before adding another project to the list. I have been thinking about dropping the ax5 and storing it until I can find more info on the swap. Carnuck: I had a feeling those relays were important. Hahah Thanks Furthermore the dust jacket(?) that goes on the internal slave is missing so I have to locate one. I'm pretty sure that shouldn't be too hard

Updated Thread. Thanks Again

Hello again. So I was finally able to get a moment to put my comanche up on Jack stands and get my first real look at what was going on. I had posted a few questions on here before and got some wonderful feedback and now that I am a little more informed, I want to try again. My name is Ant and I just bought my Comanche! It is an 88 Jeep Comanche Cheif. 4.0l Renix 5 speed 4wd Short bed. (Previously I said it was an 87, but the title says differently) The previous owner bought the truck as a project and never began. The Guy he bought it from apparently stopped driving it because the clutch slave cylinder went bad. Seems likely as there is a new slave cylinder in the cab that came with the truck, and the transmission is half out. Whoever started on it broke the trans line off of the original slave cylinder. No big deal as long as i can get it free from the coupler. So... The starter is removed. The bolts to the engine are removed (and have long since been lost apparently, anyone know where I can buy replacements? The RPM or Speedometer cable that hooks into the trans is removed. The Stick is removed. As far as I can tell, the only thing holding the trans in is the mount attached to the crossmember. Is there anything else I need to look for before attempting removal? Puegeot right? Anybody have a relay diagram? What is this Vacuum line for? It passes into the firewall and it is broken. I'm sorry to bother with all these silly questions. I know the information is out there but it becomes very hard to filter through to find what you need. I am not a mechanic. I am a novice car guy. I have worked on my own jeeps plenty but they have been newer cherokees and I learn as I go. When something breaks, I learn how to fix it. I am good with my hands, I just don't know this particular truck yet. And if I took it apart I would know how to fix it but unfortunately many things are already half apart. The Hanes manuals are so vague because they cover 1984-2001 that they are basically no help. If anybody can recommend a better manual more specifically tailored to this truck, I would greatly appreciate it. Furthermore, I am about 10 miles from Philadelphia. I have been looking to outsource some of this work to other people. For instance, the new ignition cylinder I need put in. Could I do it? Yeah probably, but I would rather save myself the frustration and pay someone to replace it. I am also really trying to get this project moving and don't have as much time as I would like. So If you are looking to make a few extra bucks and wouldn't mind coming out to my house to take on a few of these smaller projects, let me know and maybe we connect. Thanks

Well I should start getting into it next week. Thanks for the tips all.

So the consensus is to do the swap? I'm a little caught between having the parts already for the Peugeot and wanting to get it on the road, and not wanting to do all of this again in 6mo to a year. Both transmissions have 225xxx miles so its almost a toss up. Putting the Peugeot back together will certainly get me on the road sooner.

Ok Ill take a look thanks! And they didn't sell me a spare trans. I have a 92 Cherokee that runs that I had intended to make a project but it became too much. So I have all those parts to pull from

Follow up question. After doing a bit of research I believe my Cherokee parts truck has an AX-15 with 225xxx on it. It too need a needs a slave cylinder. Should I swap it out if I have the Peugeot in the Comanche? Both have 225xxx miles on it and I already have the slave cylinder for the Puegeot. 87MJTMI: Thanks for the suggestion. I have an idea to modify my existing jack to accomadate a transmission. I have a low profile that the jack plate is removable and a bunch of scrap steal and a welder. I plan to weld something up to grab onto the trans.

Green Mesa XJ New transmission? You mean the one of the XJ? I'm not sure if have to look but I'm pretty sure there is not a seam. No they were just taking the trans out, not apart. To change the slave cylinder. But I wasn't sure order of operations for removing the trans but that write up you just gave me gives me a pretty good idea. I just have to get back under and take a look to see what they have already done. I just bought it Friday and have not gotten to really dig into what has been done.

Green Mesa XJ: I'm not sure the condition of the transmission. I was told it was taken apart because it needed a new slave cylinder which I am inclined to believe because a new one was purchased and is in the front seat. If there is a problem I have a 92 Cherokee tramsmission, that ironically also needs a new slave cylinder. Also internal. I have not criss referenced the two to see if they are the same but its an option. My goal is to get this back on the road sooner rather than later. I will look into what is involved in changing the trans but for now hoping to work with what I got. fiatslug87: So your saying that the majority of the clutch is attached to the engine. I see now. Do you think clutch replacement is something I could likely do myself? I am worried about screwing something up and ruining a new clutch. It certainly wouldn't be the first time I did work on my jeep that I hadn't done before. Transmissions just make me a bit nervous. The transmission is not yet removed but the driveshaft are. So I'm wondering what else has to come off before dropping the transmission Thanks for the replies
