Replacing Pinion bearing.....how hard is it???
Ok guys, I got a 97 Grand Cherokee 2WD and I noticed a road noise/tire growl coming from the rear and its annoying. I'm thinking its the pinion bearing. How hard is it to change the pinion bearing in the axle? Could this be done in the drive way? Any special tools that I must have? Is there anything else that I could check for that would cause this explained noise? In all honesty as much as I love this JEEP I've owned it for 11 years and but its been the biggest money sponge ever.
definetly not a job for the faint of heart
its very involved

I've got this too, what are my options for fixing it? Are there any additives for the gear lube to help prolong its life or anything? Am I better off grabbing a rear end out of the junk yard?

You are better off having it rebuilt. You don't know what you are getting with a junk yard axle. It too may need to be rebuilt, and if so, you just spent $200 on that JY axle that could have went toward a repair on your current axle.

I will say from experience that this is doable but with qualification. I have done this on both my axles and on my wife's rear axle (she also has a 2wd GC Ltd.) 1st you should replace pinion and carrier bearings as either could be the culprit and while it's open do both. Also do axle seals while in there as you could damage those during the repair and removal. It is most important to take notes and record things like pinion pre-load. Get a factory service manual. Do not damage or mix up any of the factory shims as you remove the carrier and the pinion. I took the carrier and pinion to a speed shop to have the old bearings removed and the new ones pressed on. I had success with using the factory shims, maybe I was lucky but I haven't had any problems and my repairs are 2 & 3 years old and my wife's repair is 1.5 years old. If this already sounds like too much then take it to a reliable shop. I took my 1st Jeep to a "reliable" shop and that is what made me learn to do this myself.
