I have a spare set that are wobbly, the price of the bearings and seals is pretty cheap and I know it's "possible" to rebuild them just no clue what is actually involved. Anyone done or even attempted this? They are hubs from a 94 D30 that came from an XJ.

Where did you hear that you could rebuild them? It is a unit bearing and completely sealed. The only way to fix those stupid things is to replace them.

Goto any decent parts store and they sell the seals and bearings for it. With rubber seals and a bearing setup it's not as if the thing is cast together.

Are you sure you're getting bearings and seals for the unit bearing and not an older Dana 30 with lockouts? I went through this with my '91 GMC K3500, I just needed to replace the seal that was torn, can't buy it, GM part, can't buy it anywhere, even called a timken distributor, he said a box of twenty goes for $25, but he can only sell them to the GM assembly plant, ended up buying two $300+ hub and rotor assemblies from GM because it is a "non-serviceable part" I saved the old ones, figured they'd make a good trailer bearing or a cool spinning 8-lug spare tire holder.

I'll doublecheck the pn#'s to be sure. I've heard it's possible but takes some special tools, It's looks like it's just pressed in but that's just too easy. I have a set to experiment with, might as well try.

BTW, this is stupid but you (4Bangler) and I have the same name except for the middle part.

It 'is' possible. But often not recommended. If you figure out how to do it more power to you. And let us know how it goes.

Also make sure you're not looking at the bearings for the 2wd XJ's. They had serviceable bearings.



:beer:

I had tried to rebuild the 30's hub bearing assembly, maxed out a 25 ton press and had to give up. These are not very expensive if you look around. They can be had for around $100 each...make sure you get american made hubs with Timken bearings.

The later 2wd XJ's also used the same bearing hub assembly...only the early XJ 30's had the conventional car like bearings on a spindle.

ALSO...you will not be able to use those 94 hub bearings on your 89 XJ unless ya change out everything from the outer knuckle out. This includes the knuckle,caliper,and brake rotor.

When I had a 30 I got spares at the pic n' pull for $25 per unit. All in good shape and off highway XJs. You can get some damn good junkyard spares off soccer mom xjs. Every CV shaft I've taken has not needed a re-build (although this is FL)

Yea, you can rebuild them, seen it done, it's not too hard. You should be fine with a 94, but I believe that I heard somewhere that the 97-newer TJ's aren't rebuildable, different design.

Ditto what IndyCJ said. There's actually an illustration of the exploded view of one and a procedure for re-building them in my Haynes manual (SWB Jeeps up to 1987) if I'm not mistaken...

In that case... anyone know if a hub assembly from a 95 and earlier D30'd rig would work on a 97 and newer TJ?

Nope, won't work. Tried it on my buddies rig a couple of months ago.

Something's different, can't recall what exactly, but something is.

I maxed out a 55 ton press trying to press apart some from a TJ....

Amen to that, I was just curious as to the possibility of it and it sounds like more of a PITA than it's worth. Just checked my local yard and they want $35 per hub for a set off a 96 so that's a heckuva lot better than forking over three times that for new ones.
