Submariner Posted January 2, 2019 Share Posted January 2, 2019 I got a lead on a dana 44 with 3.73 gears from a 99 grand cherokee to swap into my 88 mj. how much of that it going to have to change the perches and shock mounts. He only want $75 for it. Suggestions and recommedations please..... Link to comment Share on other sites More sharing options...
mjeff87 Posted January 2, 2019 Share Posted January 2, 2019 ZJ 44's have an aluminum housing. I'd not waste the effort. Link to comment Share on other sites More sharing options...
Jeep Driver Posted January 2, 2019 Share Posted January 2, 2019 Junk, don't do it. Find a 8.25 Link to comment Share on other sites More sharing options...
Pete M Posted January 2, 2019 Share Posted January 2, 2019 99 wouldn't be a ZJ. but it'll have the wrong bolt pattern. Liberty 8.25s are everywhere in the 'yards. Link to comment Share on other sites More sharing options...
gogmorgo Posted January 2, 2019 Share Posted January 2, 2019 The ZJ and WJ guys seem to think the aluminum centred d44 is a beefy axle. Literally no one else does. Not many people have built ZJs, although they're getting a little more common. But yeah, like Pete said, the lug pattern doesn't match the MJ's.

Not many people have built ZJs, although they're getting a little more common. But yeah, like Pete said, the lug pattern doesn't match the MJ's. I owned a '99 WJ with the aluminum "D44." It's not good enough to be classified as a turd. Here's a factoid I uncovered in going through the factory service manual. They didn't mention this is the owner's manual (God forbid they should tell the owner anything useful), but in the FSM they specifically said NOT to jack up the rear using a single jack under the differential. Why? Because the stress will warp the diff housing where the axle tubes enter, and the diff will be ruined. Of course, it wasn't necessary to jack it up to make that axle whine. Mine was noisy from the day I picked it up. The factory eventually sent a technician from Jeep to rebuild both of my axles in the dealership's shop -- after which the noise was worse instead of better. And, of course, as has been noted the wheel bolt circle is wrong. DO NOT buy this axle. Link to comment Share on other sites More sharing options...
