ZJ Aluminum Dana 44

Edit. Fat fingered thread title, should be "ZJ aluminum Dana 44"

Need some info on the aluminum Dana 44 rear axle in the 93-98 Grand Cherokee.

Searched here at JeepForum and googled, still some gaps.

Width - wheel mounting flange to wheel mounting flange??

Are they light as feather compared to an iron center section 44 or still a heavy mofo? If anyone has had one on a scale, any actual numbers?

If I decide to look for one in the local salvage yards, were they installed across the board on all the ZJs those years, only certain years, or only with certain engine or option packages??

93-98 Grand Cherokee = ZJ; 84-01 Cherokee = XJ.

WMS-WMS on the ZJ D44a is about 60.5".

I'm not sure about the weight.

The D44a was used in V8 ZJs from 95-98.

Its not a good axle for a swap. It has very limited aftermarket support. Aussie is the only locker available for it and they're not even being made any more.

The aluminum 44 weighs @ the same as a D35. They have a lot of problems with preload and bearing failures. You would be better off swaping in an iron 44 or maybe an 8.8.

Look for 96-98 ZJs with the V8, the only ones they were used in.
