I read somewhere that the front wheel bearings on the XJ were a royal pain-in-the-a** to replace. I want to replace all the wheel bearings..

What do you guys know??

Thanks again!

They are not really that hard as long as they have been out before.
The bearings are in hub assembly. About $200.00, shop around you can find cheaper.
1) remove the axle sahft nut and cotter pin
2) remove the three 13 mm 12 point bolts that hold the hub to the knuckle
3) remove the caliper and rotor
4) with a little or lots of effort remove the hub

This thread has some pics of the three bolts that need to be removed to get the hub bearing out of the knuckle

The axle shaft nut is held on at a high torque (somewhere around 200ft/lbs). So you'll need either air tools, or a a good strong 1/2" drive breaker bar & cheater pipe. You'll also need a torque wrench that reads high enough to be able to torque the nut back on.

Do I need to replace the entire hub assembly..or do I just need the bearings?? I also read somewhere that it's better to replace the hubs with ones that allow you to replace bearings easily later.

thanks again!!

It is a sealed assembly. To do the bearings, you replace the entire unit. It is a non-servicable part.

The last time for me was 1992. Cost about $400.00.
To do both sides. The bearings and seals could only be gotten at two
different NAPA stores and then I had to take the hubs to a machine shop to have the bearings and seals installed. $35.00 each hub
At that time it was cheaper to go that route. Today I would buy a hub assembly with out thinking.

I've found the hubs for as low as $64 on Ebay... not sure if it's a great idea to buy those though.

Also, '99 was a transition year for the hubs.. apparently in that year they changed the hubs from a composite to full cast .....

Any idea how I can tell which ones I Have??

DC changed the rotors from composite to cast. The hub construction is essentially the same but the dimensions are different.

Most parts places screw up getting you the right bearing. If you can, take one with you to the parts store and make sure what they give you is identical to what you've got already.

I used Quadratec Bearings for my 92 XJ

Part # 52417+04

HUB ASS. 90-95YJ 97-99 TJ 90-99 XJ ZJ 53007449

$129.99 Each

May locate them cheaper but I was in a hurry and they were correct part the first time.

They included all new wheel studs already pressed in too. I used antiseize on everything!

I followed this as a guide:

When I did mine I followed this guide just to throw up another resource.

Also a good place to check out DIY instructions for brakes and lift kits.
