dybamx Posted May 11, 2015 Share Posted May 11, 2015 I just picked up a pos 2000 XJ, what parts are an upgrade for my 87 Comanche? I am planning on using the rear axle, maybe the front axle and swapping the doors. Are the booster and master cylinder worthwhile? what else? I'm not a fan of the newer front and this one needs some work, so I will be keeping the 87 sheetmetal. Link to comment Share on other sites More sharing options...

schardein Posted May 11, 2015 Share Posted May 11, 2015 The rear view mirrors can be swapped if you weren't swapping the entire door. Wiper transmission might have less wear in the bushings if it is lower mileage than your MJ. Which transfer case does it have? NP242 has the full time option. Are the wheels the 16" TJ/LJ Rubicon Moabs? If so those are nice. I believe some people swap in the center console to get drink holders. Engine will have the late model intake manifold and power steering bracket/pump (if it is a 4.0) which is an upgrade for earlier HO Jeeps. Not sure if it will work on Renix. Don't know if the dual diaphragm brake booster is a direct swap. I would check the speakers to see if they are upgraded. Front doors/rear sound bar use 5 1/4" speakers which are a direct fit for MJ door speakers. That's all I can think of now... Link to comment Share on other sites More sharing options...
Incommando Posted May 11, 2015 Share Posted May 11, 2015 You can use the shafts out of the front axle but the axle itself is the weaker low pinion design Link to comment Share on other sites More sharing options...
dybamx Posted May 11, 2015 Author Share Posted May 11, 2015 thanks, I'm pretty sure the transfercase is a 231, it has that funky output shaft with the rubber boot (slip yoke eliminator maybe?) is that any better to use? It looks like a weaker design to me. The wheels are 16s, I do like them, but I'm not sure if I'm going to keep them or sell Link to comment Share on other sites More sharing options...
Incommando Posted May 11, 2015 Share Posted May 11, 2015 The later transfer cases( rubber boot) have a sealed output shaft. That means that if you break your rear driveshaft or in some cases your rear end you can take your driveshaft off and drive it as a FWD. The older ones do not do this and if you pull the driveshaft off or even out ( which can happen if you have a lot of flex) then all of the T-case lube runs out and you are done. Although they are both the same strength this revision is a great improvement over the earlier set-up. The easiest way to be sure of the t-case is to look at the gear shaped tag which faces to the rear of the case or look at your shifter. 231 is 2hi 4hi N 4lo while 242 has an added position for 4fulltime Link to comment Share on other sites More sharing options...
dybamx Posted May 11, 2015 Author Share Posted May 11, 2015 thanks, I will check it out, just brought it home last night and won't have time to look at anything until tomorrow Link to comment Share on other sites More sharing options...
dybamx Posted May 12, 2015 Author Share Posted May 12, 2015 You can use the shafts out of the front axle but the axle itself is the weaker low pinion design so, I can replace the CAD with the one piece shaft from this? Link to comment Share on other sites More sharing options...
dybamx Posted May 12, 2015 Author Share Posted May 12, 2015 and it is a 231 T-case. i will be swapping that into the XJ trail rig Link to comment Share on other sites More sharing options...

Big joint shafts. Don't forget the inner seal when replacing when replacing the two piece shaft Link to comment Share on other sites More sharing options...

yxmj Posted May 13, 2015 Share Posted May 13, 2015 The intake and exhaust manifolds. Link to comment Share on other sites More sharing options...
Rockfrog Posted May 13, 2015 Share Posted May 13, 2015 The exhaust manifolds from 2000 up are incompatible with previous heads. The intake will work. And it's use will require some throttle body decisions to be made. Adapting the Renix TPS is bone simple, I made mine from some scrap aluminum flatbar, a cheap 8" drill press (a hand drill would have worked as well) and some hand files. Valve cover works using the earlier gasket. The later power steering pump setup is far superior in adjustment and will bolt right up to a Renix, along with the intake. Booster and master will swap in the usual manner. Complete front clip will swap if you wanted to. If you do take the header wiring harness plug and splice it into the stock harness - newer, better, less corroded plug. There is actually a lot that is compatible between the two with a little work. And a lot that isn't so much (engine management) unless you make some major changes. Link to comment Share on other sites More sharing options...
dybamx Posted May 15, 2015 Author Share Posted May 15, 2015 is the manifold that much better? Link to comment Share on other sites More sharing options...
Incommando Posted May 15, 2015 Share Posted May 15, 2015 Some people claim gains with the newer intake. jP magazine lost horsepower after the swap Link to comment Share on other sites More sharing options...
dybamx Posted May 17, 2015 Author Share Posted May 17, 2015 that's good to know, I think I'll stick with the Renix manifold Link to comment Share on other sites More sharing options...
