Default D44a

I have a '93 ZJ limited with a 4.0 and the axle I think is a D35 and it has a bad pinion seal. I bought a D44a to swap in, but now I am kinda leery after reading Peterson's recent 4wd edition. Has anyone had any experience with this axle?
Good, bad, or ugly?

Yep. POS. Sell it to someone else. Get an 8.8 and install that instead.

Doesn't take Dana 44 lockers, has C-clips, and has a crappy aluminum case that spins bearings.

I wouldn't say it is a POS. It has VERY limited aftermarket support, particularly lockers, but strength wise it will hold up to 33s locked easily. The other nice thing about it is that it is a direct bolt in for you. If you don't do a ton of wheeling or plan on tires >33" keep it.

I would say it is a POS. As stated above, it will spin bearings in the aluminum housing and will need to be rebuilt on a normal basis. A set of 33's with a locker will eat that axle for lunch if you wheel very hard for very long.

Even my street queen 5.9 with the 44a in the rear had the axle rebuilt 3 times so far in only 64,000 miles. They can't handle the weight of the ZJ. I talked with one of the performance/testing engineers that worked on the D44a design project. They could not get them to stop spinning bearings, yet the big chiefs said to ship them anyway. Even from the factory, they knew they were crappy axles at best.

Well if you talk to people over at JF they seem to have no problems with them...it is entirely possible that you have a unique 44a. It is known for spinning bearings, but once every 20k miles is ridiculous, most people aren't needing to have them rebuilt until after 100k. And YES it will hold up just fine to 33s locked.

I wonder how hard it would be to take an old 44 housing and press 44A tubes into it.

well i do axle work for a living and i refuse to do any mods to these p.o.s because they wont hold up and the customer will be mad. they are not worth the time or money spent on them. they do offer good scrap weight though.

At least the axle hasn't need a darn thing done to it in over 4 years. :tonka:
