JeepcoMJ Posted April 19, 2009 Share Posted April 19, 2009 I have a 1990 ax4 internal converting to 1998 ax5 external you need whatever it takes to make a 98 trans work in a 98. hopefully you have the proper slave cylinder, throwout bearing and plate. you have the 98 bellhousing? do you have the parts for inside of it? it shouldn't be too hard if you have that all. being that not many guys here have ax5's or ax4's and/or are simply getting rid of theirs with a 4.0 conversion, I don't think that many people here will know exactly what parts are in a 98 trans bellhousing...

I didnt if or how the slave cylinder lines would bolt up . you may have to use a 98 master cylinder with it. is the 98 slave plastic? or is is steel? ...it's all going to be piecing it together until it works...

pug Posted April 19, 2009 Author Share Posted April 19, 2009 It is plastic it was out of a wrangler. So i have to get a98 cherokee slave cylinder the wrangler will not bolt up. Link to comment Share on other sites More sharing options...
pug Posted April 19, 2009 Author Share Posted April 19, 2009 Do you think it would be easier to take internal bellhousing and retainer front bearing and swap it. Then just have a internal slave cylinder on the ax5. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted April 20, 2009 Share Posted April 20, 2009 Do you think it would be easier to take internal bellhousing and retainer front bearing and swap it. Then just have a internal slave cylinder on the ax5. nope. the bearing retainers are different sizes since the 98 trans has different bearings. thus, the bearing retainers are different. just use the 98 parts.

pug Posted April 20, 2009 Author Share Posted April 20, 2009 Thats what i thought. I have never attempted this so just trying to make it as easy as possible. thanks Link to comment Share on other sites More sharing options...
pug Posted April 22, 2009 Author Share Posted April 22, 2009 I started taking apart clutch mastercylinder (1990) and compared with the new one (1998).They are to differant sizes about 1 1/8 differance. Is there anyway i could get a custom made line so i can use 1990 master cylinder. Link to comment Share on other sites More sharing options...
Pete M Posted April 22, 2009 Share Posted April 22, 2009 I used a two dollar brass 1/4"-5/16" compression fitting to adapt my '99 slave line to my '88 master line (AX-15 though I don't think that matters). Still working great after 7 years. :thumbsup: Link to comment Share on other sites More sharing options...

pug Posted April 22, 2009 Author Share Posted April 22, 2009 One more question. Did jeep ever come out with a factory heavy duty clutch for 2.5. I am only going to run 31s. thanks Link to comment Share on other sites More sharing options...
Geonovast Posted April 22, 2009 Share Posted April 22, 2009 One more question. Did jeep ever come out with a factory heavy duty clutch for 2.5. I am only going to run 31s. thanks I wouldn't worry about the clutch. Upgrading the clutch is something you really only need to worry about when you're running high horsepower. If you're concerned about tire size, axle gearing is more what you should be worried about. If you're running 31s and a 2.5, you're going to want AT LEAST 4.10s, but lower would be much better. Truck is originally a 4 speed right? Chances are you have 3.55. Link to comment Share on other sites More sharing options...
pug Posted April 22, 2009 Author Share Posted April 22, 2009 I did have the 4speed. I also put in a 8.8 with the 4.10 and disk Link to comment Share on other sites More sharing options...
