Sorry for the slow reply. The crankshaft is secure and does not move at all, axially. I don't believe the thrust bearing is to blame. I'm thinking the motor and transmission mounts are trash. I'm not going to bother replacing the pukey mount, but I will replace the MM's. I'll post an update next week. Edit: Thanks for the help, all. No opinions are unwanted here!

Use a Dremel with a coarse bit and grind that sucker out. If you're more adventurous, you could always use a blowtorch to heat up the surrounding metal. The expansion of the crankshaft should cause the spacer to fall right out.

I was hearing a loud screeching noise every time I depressed my clutch pedal. Thinking it was my TOB, I replaced it and threw it back together only to find that it was still a screechy mess. So I decided to replace my pilot bearing, which was jammed so tightly in my crankshaft that I had to resort to using a dremel to grind the thing out. Alas, no respite from the banshee screech. So after tearing apart my drivetrain and putting it back together twice in one weekend, I realized the noise coming from me disengaging the clutch was caused by the engine side of the flywheel grinding up against the dust cover. I apologize for the terrible picture quality, but the scoring goes almost halfway around the plate and the flywheel had carved a crevice almost 2 millimeters deep in some spots. I tried bending the plate, which didn't make any meaningful difference. I "solved" the problem by slapping a couple of thick washers as spacers on the bolts at the bottom of the bellhousing, but I'm worried this may be a symptom of a larger problem. Does anyone have any advice to offer? I think my motor mounts may have failed and threw my alignment out of whack.

Urgent update: I just replaced the TOB and the screeching noise hasn't gone away. I really want to break something. What did I miss?

I was planning on doing a full AX-15 swap this summer and was hoping that the POS that I bought would be enough to limp back home in May. Obviously, I was wrong. I should have known, the instructions were in Chinese... As much as I don't like getting crappy parts, the internal slave/TOB assembly is so ridiculous that I can't justify spending more money than I have to on it. Edit: This time I bought a Dorman. Any info on how well they do?

I thought 80-110 seemed a bit low. 8-10 hours at New England labor pricing sounds like a considerable dent in my wallet.

I drive an 88 4x4 long bed w/ pukey tran. I bought an exedy clutch kit 5 months ago and the slave cylinder/TOB already crapped out on me. I'm strapped for time and I would like to avoid dropping my transmission without proper tools again, considering how miserable that experience was. Does anyone know what labor would cost for the replacement? I already have the part and have gotten online labor quotes at around $80-110. Does this seem accurate? Thanks for the help.

Within the last 30 seconds of my last drive, my comanche started making this horrible high-pitched squealing noise. This noise only occurs when I depress the clutch pedal / disengage the clutch. The noise persists for as long as the engine is on and the pedal is depressed. I think I may have also lost some clutch pressure but cannot tell for sure. I think it may have been some small particle finding its way in between the clutch and the flywheel, as it sounds a bit like grinding. Most of the other research I've done points to the possibility of it being a bad throwout bearing, but I sincerely hope that is not the case as I just replaced the internal slave cylinder / throwout bearing assembly less than 6 months ago. Thanks for the help Edit: Transmission is a pukey.

I just had this problem last month in my 88. Internal slave/ Pukey 5 spd. What actually caused the sticking and eventual failure for me was the spring in the master cylinder breaking in two. I did a full slave/master replacement and solved the problem, as the slave was definitely on its way out as well.

Here, I tried to show on this picture where exactly the weld failed. Credit to Matthew Currie from the naxja forum for the original photo.

Soo... I must have the worst karma ever. :wall: Just a month after a full slave / master replacement, my actual clutch pedal failed. I'm sorry I don't have pics, but the weld failed right up at the pivot point the first time I depressed the pedal this morning. Does anyone know if this is weldable, or even should be welded? Should I be buying a replacement pedal assembly instead? Thanks in advance for the help.

I had just noticed this! Glad someone else caught it too :cheers:

The tube is between two or 3 feet long and I remember seeing the top of it poke out near the washer fluid tank. I've finished the clutch replacement, and I will check it tonight and get back to you on whether I find the hole. Thanks for all the help! :wrench:

There is not, but I cannot find a hole either. I don't doubt at all that that is what this is now, after having done more research... I'll have to do a more thorough search for that hole tomorrow morning.

The transfer case breather on mine is a tube with a hose clamp on it. It runs alongside the transmission breather and they both end in 90 degree metal fittings. I swear, this one is giving me quite a tough time :hmm:

No dice, I can't seem to find that hole you mentioned.... I'm beginning to think the previous owner may have swapped axles and left the vent hose in by mistake?

That's actually what I was originally thinking! I already have the vent hose on my Pukey transmission though... I'll go take another look at my differential and see if I can find the hole you described. Thanks!

Hi there CC. This is my first post here, so bear with my lack of knowledge. I've been changing the entire clutch assembly (SC, MC, clutch pad, pressure plate, etc.) out in my 88 MJ for the past week between my college classes (hard as hell to do alone and without the correct tools). The good news is that I'm just about done. Then I found this. I was looking all over for the hole it came out of, but wasn't able to locate it. I'm guessing its some sort of vent line, maybe for the differential? If anyone knows what this is, the help would be greatly appreciated. Thank you!
