87sparTruck Posted September 24, 2013 Share Posted September 24, 2013 What kinds of issues would you run into putting a 92 mj front axle in a 99 xj? Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted September 24, 2013 Share Posted September 24, 2013 None... direct bolt-on swap. '90 was the last year for the vacuum disconnect, so no worries there. Edit: '90 was not the last year of the CAD, but that doesn't make a difference as far as swap-ability. Link to comment Share on other sites More sharing options...
Rockfrog Posted September 24, 2013 Share Posted September 24, 2013 precisely ... my current axle in my '00 XJ came from an '89 limited. You could even bolt in a CAD axle or a 2wd beam axle as a direct bolt on swap. Or, one from a ZJ, or a TJ .... as long as the gearing matches, the suspension are the same on the front.

Except the ZJ and TJ had low pinion front axles. They'll still bolt in, but they aren't the same. Link to comment Share on other sites More sharing options...
mvusse Posted September 24, 2013 Share Posted September 24, 2013 00 and 01 Cherokees were also low pinion. Link to comment Share on other sites More sharing options...
gogmorgo Posted September 24, 2013 Share Posted September 24, 2013 None... direct bolt-on swap. '90 was the last year for the vacuum disconnect, so no worries there. My '91 has one... The issue you'll face is taking part of a rather rare '92 Comanche to put in a common old XJ... Just kidding. go for it. Link to comment Share on other sites More sharing options...
FrankTheDog Posted September 24, 2013 Share Posted September 24, 2013 My "rare" 92 MJ has an 87 D44 rear and a 97 XJ D30 front. My other 92 has an 87 D35 rear and 98 TJ D30 front. Also, although the ZJ and TJ are both low pinion, they are not the same. The TJ has a shorter pinion shaft than the ZJ. ZJ and CJ D30 gears are interchangeable. Not TJ's though. But like said above they will all work in each other. Just have to watch your drive shaft lengths. Link to comment Share on other sites More sharing options...

FrankTheDog Posted September 24, 2013 Share Posted September 24, 2013 What other parts do you have from the 92? Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted September 24, 2013 Share Posted September 24, 2013 I thought '90 was the last year for CAD? :hmm: I'm sure I'm mistaken, though... :doh: As mentioned though, all years will work. One more thing to keep in mind that hasn't been mentioned is for anyone who has ABS braking. If you get an axle from a non-ABS equipped Jeep, you'll have to do some modifications there to retain ABS. Not sure if ABS was ever used on an MJ, though... :dunno: Link to comment Share on other sites More sharing options...

My "rare" 92 MJ has an 87 D44 rear and a 97 XJ D30 front. My other 92 has an 87 D35 rear and 98 TJ D30 front. Also, although the ZJ and TJ are both low pinion, they are not the same.

Just have to watch your drive shaft lengths. and For more clarity on this one ... 1993-1996.5 used a special crush sleeve design pinion. After 1996.5, the ZJ used a TJ style gear set (short pinion) with crush sleeve. TJ gears will NOT work in a CJ. CJ gears WILL work in a ZJ (1993-1996.5). TJ gears WILL work in a ZJ (1996.5-1998) Link to comment Share on other sites More sharing options...

yxmj Posted September 24, 2013 Share Posted September 24, 2013 Not to bee off topic but further too the CAD...My 93 YJ still has it so it might have gone longer in the XJ as well Link to comment Share on other sites More sharing options...
Rockfrog Posted September 24, 2013 Share Posted September 24, 2013 The YJ had it until the end in the 95 model year. I think 93 was the last year for XJ's Link to comment Share on other sites More sharing options...
87sparTruck Posted September 24, 2013 Author Share Posted September 24, 2013 I have a few odds and ends from a stripped 92 4.0 auto. That front axle with rotted perches 3.55's, washer bottle, coolant bottle, cut up 4.0 harness, 4.0 engine mounts, front springs, rotted fenders, auto column, ebrake minus the release mech, brake booster, steering box, hood hinges and wiper motor.

FrankTheDog Posted September 25, 2013 Share Posted September 25, 2013 What's left of the harness? Link to comment Share on other sites More sharing options...
87sparTruck Posted September 25, 2013 Author Share Posted September 25, 2013 Previous owner cut it to take the engine out, so most of it is there. Link to comment Share on other sites More sharing options...
FrankTheDog Posted September 26, 2013 Share Posted September 26, 2013 How about the rest of the wiring harness? Where was it cut? Do you still have the cab and body harness Try to save as much of the 92 harness as you can. Makes it real easy to adapt a later 93-98 XJ motor into an MJ.

87sparTruck Posted September 29, 2013 Author Share Posted September 29, 2013 I believe cab wiring isn't there. The whole dash was removed before I got it. Link to comment Share on other sites More sharing options...
