Some guy offered me a D30 complete with brakes from a 2004 Grand Cherokee for $25. Has this swap been done? And if so, is it a direct bolt in or does some work need to be done? Is it worth the effort? It would give me a headstart on upgrading my braking. Thanks for any info on this one.

If it's a low pinion you should rob the knuckles and brakes and do a WJ knuckle conversion on a your axle, assuming that yours is a HP30.

I actually think everything is different. Even the WMS. I have personally confirmed that a stock WJ tie rod with WJ ends will not fit between the knuckles on a XJ 30.

I dont consider myself hugely knowledgeable but remember asking about this years ago for similar reasons. I was told that the WJ axle may have better brakes but was otherwise a POS. Many compromises to the soccer-mom set. I suspect the spring mounts are different. I think it was mentioned that the case is weaker, maybe aluminum?

The knuckles are highly sought after due to the ease of building a strong hi-steer set-up. The later Akebono dual piston calipers have considerably more stopping power than the OEM single piston calipers found on XJ's.

OK I own a 04 WJ and a XJ. The problems with a WJ D30
5X5 lug pattern
LCA mounts are further inboard and lead to DW problems with as little as 2" of lift on a WJ.
CV axles
Low pinion
The good things
steering knuckles are easy mod for high steer on a XJ D30 and they have BIG calipers and steering arms.
and that is about all. Hope this helps. The WJ D30 is not really worth the work to put it in but the parts on it are worth big $

The WJ D30s do have better stopping brakes but are notorious for warping rotors. If you use the WJ brakes don't use the factory rotors. Even the ones from Autozone seem to last longer. Also be sure to torque the lugs evenly.

There is a TSB on this issue. It was corrected at the factory level in ~2002. IIRC the original calipers were Continental-Teves, the replacement was Akebono. Or maybe I have that backwards... search and all will be revealed.stoneattic said:

It was? I just took my 04 in to have the warped rotors replaced under warranty and the out come of the class action lawsuit that Jeep lost. You get a one time free replacement then it is on you.

And if you had already replaced the rotors yourself before the class action suit you need to have receipts to be reimbursed and you only get reimbursed for the parts. Also, according to other WJ related forums JU & NAGCA) the new ones warp too.
