WJ rear wheel bearing install question.

Im am going to need to replace the wheel bearings/seals on a 2004 GC soon. I watched a few youtube vids on it. One question I have is; do I pack the new bearing with grease or not? Im thinking 'not', but one vid suggested it, So hence the question to the experts. Thanx a lot.

I always thought that the bearing was lubricated with the fluid from the differential, but the service manual also tells to put grease in the bearing.

Re: WJ rear wheel bearing install question.

Must say I didnt pack grease in mine. Just poured diff oil in them before install.
The way I see it, the bearings rely on the diff oil for lubrication when driving. I use the expensive synthetic oil in my diffs with the mopar additive, so why mix bearing grease as well ?
Almost 2 years later all is running fine.

A little Bearing Grease wouldn't hurt.

Re: WJ rear wheel bearing install question.

Is changing the bearings as easy as the youtube videos show? Anything to watch out for? I've got to change the bearings in our 240K miles 2000 laredo (one seal is oozing & the other bearing has a slight howl).
thanks,
Mike S

Re: WJ rear wheel bearing install question.

Yeah Mike its super easy. Its only two bolts on caliper bracket, and 4 nuts holding axle in place. Spayed on blaster and drained oil, night before, after seeing the you tube vids, I gave it a whirl. The vids tell the story. The die grinder method works great. Getting the race out of the housing was a mm at a time marathon but came out without tools. Midas gave me estimate of 450. Dealer was around 600?? whoa!! You can do it in less than 3 hours. and 100.00 in parts and oil. When you set your jack stands, put them inside the shock mounts, so they are out of the way for the bottom axle bracket nut. Good luck

Re: WJ rear wheel bearing install question.

Got the left rear bearing swapped out last night. Yes, it was just as easy as it appeared, although I did have an issue with the new brake pads (I replaced the rotors & pads while I had it apart). The new pads were so thick, I had to cut a portion of the 3 little "fingers" off of the rear pad (the ones that hold it into the caliper "puck") to make room to get the pad installed.

I'll get the passenger side done as soon as I get another rear axle seal (forgot to order 2).
