Jackrabbit41 Posted July 26, 2015 Share Posted July 26, 2015 So it rained here in the northwest, big surprise i know, and my door wasn't all the way shut so my carpet got sopping wet. Ive looked under my carpet all ready and on the drivers side there is surface rust and one thumb size hole. Every where else is perfect condition so I'm pumped about that. My first question is if this plan i have sounds like it'll be good. First ill put in a patch, then sand every thing down, then primer it, then paint it black and then hit it with a rubber coating. Also there is a hole ok each side hat goes through the floor pan and the frame. Can I weld a cap over those? Seems like water would Come through them? There definitely a factory thing Next, i was under my truck and noticed some seaping from the tranny and places around the motor so i check some of my fluids and my oils good but not the master cylinder or the power steering fluid.. My clutch went out a few weeks ago and the mechanic fixed the master cyclinder and while it was in there i had them change the oil and check the tranny fluid and they said everything was good. Well that was 2 weeks ago and now my master cylinder fluid is on low and same with power steering fluid. What kind of fluids do i put in the master cylinder and power steering? Ive never done anything with those and it doesn't say on the caps and i don't have a manuel. And does anyone have any good ideas for a good replacement for the carpet? I hate it cause after work it always gets so gross and greasy. Id like to do linex in but I don't have the money Also how do i check the tranny fluid? and does anyone know where i can get a manual for it? I have a cherokee manual, but id like a comanche specific one. thanks again Link to comment Share on other sites More sharing options...
Eagle Posted July 26, 2015 Share Posted July 26, 2015 Brake master cylinder gets brake fluid. The basic stuff is DOT-3. Better is rated DOT-4, which is probably synthetic. Both of those will destroy paint instantly upon contact, so be careful. Best (IMHO -- others disagree) is DOT-5 rated silicone brake fluid. It's more expensive, it doesn't attract moisture (water) like DOT-3 and DOT-4 fluids do, and doesn't harm paint. Clutch master cylinder takes hydraulic clutch fluid. You probably won't find that at Wal-Mart but you should find it at Auto Zone, Advance, or any decent auto parts store. Power steering takes power steering fluid. In an emergency you can use ATF, but it's better to use the stuff that's formulated for the power steering. If your clutch master cylinder is losing fluid, check your fuse panel under the dash. That's where the leaks usually drip, and the hydraulic fluid corrodes the contacts very quickly. That's why I prefer to use silicone in the clutch -- it's non-corrosive.

The clutch master cylinder is the thing all the way to the right in the corner of the engine bay right? The thing to the left of the brakes? I was just looking and what I think is the clutch, it says to put in dot 3 fluid. My clutch master cylinder was just replaced and this thing I'm looking at looks brand new too but it says brake fluid in it Link to comment Share on other sites More sharing options...
Eagle Posted July 26, 2015 Share Posted July 26, 2015 The 2000 XJ FSM calls for DOT-3 brake fluid, or Mopar brake fluid. That said, there are hydraulic fluids that are formulated specifically for clutches, and I have a can on my shelf. However, because of the possibility that clutch master cylinder leakage will destroy the fuse box, I use DOT-5 silicone brake fluid in the clutch (as well as in the brakes, but that's for other reasons).

Thanks I'll have to start using that. Should I drain all the old fluid before I put in the different dot 5? Link to comment Share on other sites More sharing options...
87MJTIM Posted July 27, 2015 Share Posted July 27, 2015 You stated the clutch master cyl was replaced and that you lost fluid two weeks later. Also, you noticed fluid coming from the bell housing. That suggests to me a bad slave cylinder. If your 87 has the BA10, that means dropping the trans and replacing the (whole trans with an AX15 with an external) slave cylinder. As for the carpeting, I replaced mine from Custom Interiors. They were able to match the original color. I purchased a reprint of the 87 FSM off ebay. Be aware that for 87/88, Jeep just took the 86 FSM and added TSBs and supplements for the later years. Link to comment Share on other sites More sharing options...
Eagle Posted July 27, 2015 Share Posted July 27, 2015 Thanks I'll have to start using that. Should I drain all the old fluid before I put in the different dot 5? Yes. Silicone can co-exist with DOT-3 or DOT-4 brake fluid, but they don't mix and if you don't get rid of the old stuff you don't get the benefits of using silicone. By the way, it's expensive -- get ready for sticker shock. Fortunately, the clutch doesn't take a lot. As 87MJTIM noted, it sounds like to also need a slave cylinder.

What years of Cherokee should I start looking at for an manual ax15? Or what other models that have them Link to comment Share on other sites More sharing options...
87MJTIM Posted July 27, 2015 Share Posted July 27, 2015 Mid-89 MJs and XJs have the AX15. However, these were also internal slave cylinders. Jeep switched to the external slaves with the 94 yr. So, look for a 94+ AX15 or get an earlier yr and a bellhousing for the external slave system. Be aware that in 98 (?) the input shaft size changed. You will have to change the pilot bushing to fit the input shaft. Link to comment Share on other sites More sharing options...
Jackrabbit41 Posted July 27, 2015 Author Share Posted July 27, 2015 Also has anyone had experience with extreme truck shocks? I was given some brand new ones and I would like to put them in when I go to my 6 inch lift so I don't have to buy shocks Link to comment Share on other sites More sharing options...

Crash Posted July 28, 2015 Share Posted July 28, 2015 Yes, 95+ for sure. Or even a NV3550, if you get lucky. Link to comment Share on other sites More sharing options...
