Replacing the dying D44a

Hey guys, I just picked up a 5.9. The rear diff is making that grinding noise, so the bearings are bad.

I found a WK2 rear axle, 3:73 (2012) for $80. Aside from the different bolt pattern, will this fit my zj?

Thanks for any help. Can't find anything on this swap.

I thought the wk2 had a independent rear axle. I would doubt it would be an easy swap.

Why not another d44a or a for 8.8?

If that's the case, then the seller is mistaken. He said it was from a 2012 GC. The CL listing shows a solid rear axle. I'm interested because it's only $80 and it only has 3500 miles on it.

I'm hesitant to put another ZJ D44a in it, because it could be bad as well. The 8.8 option would run me about $400-500 if I install.

Thanks

The WK2 is definitely independent rear suspension. It could very well be the case that it uses the D44a center section. I don't know. Either way you ain't bolting it into a ZJ.

When dealing with 15+ year old vehicles your options are limited. If the rig is a long term project then spend the $ on a proper rebuild or swap in a another axle (which in the case of a Ford 8.8 is probably soon to require a rebuild itself.) Otherwise, roll the dice on a junk replacement.

Honestly I would just rebuild the 9er d44a. It's not a bad axle.

Thanks for the replies guys. I've confirmed the wk axle won't work. I'll have to shop around for some prices on those bearings, or try to find a low mileage d44a. Every d44a w over 120k, that I've been in grinds tho..
