how do I change my rear differential bearings?

not my wheel bearings, the bearings in the pumkin .. I changed my wheel bearings and I still have a bad bearing grind/whine coming from my rear end at low speed .. almost sounds like a brake dragging but I know for a fact it is not.. if someone can give me steps on changing these that would be awesome.. I just dont wanna mess my gears up or have my spiders fall out or something. so the proper way would be appreciated

Have you opened up the differential and taken a close look inside at things?

If not, you very well may discover that if the pinion bearing is toast - the ring & pinion gears, plus the spider & side gears could be worn or chipped as well.

If this is the case - a complete rebuild including a new ring & pinion, spider & side gears, plus a new master install kit will be in order to "fix" it.

This will require pressing bearing, specific specialty tools & knowledge, & if a shop does it $$$.

If it were my Jeep & the D35 needed repair, I would toss it in the nearest dumpster & install a better axle for far less than it cost to rebuild the factory axle.

It may be easier to install an 8.8 than replace those bearings and much more worth the time!
