Findind what rear end i have to order the correct bearing and seals
SOURCE: rear axle bearings need replaceing I hear grinding
Go to Jeep and buy a bearings, seals, and collar. The bearing is held in place on the axle by a keeper collar. This must be cut off to get the old bearing and seal off. Use a wizz wheel to cut it and then whack it with a chisle
To get the axle out. Remove rear diff cover, and wheel and start taking apart. It's not a terrible job, but if you aren't very mechanically inclined, take it to a shop. Make sure you use the correct fluid in the differential.
SOURCE: Rear Axle Seal Replacement
remove rear tires, then remove brake calipers and rotors, then remove the 4 nuts (each side) that hold the axle shafts to the axle tube (located around the axle tube behind the backing plate) then using a slide hammer pull the axle shafts out, next using a die grinder and an air hammer get he retainer collar and the bearing off (without damaging the axle shaft) then remove the seal and the outer race which will still be in the housing. next put it all back together, make sure the plate with the studs is still on then slide the seal, bearing, then retainer on (all new parts) and using a press push them all the way back on. then is simple reassembly.
SOURCE: REAR AXLE SEAL LEAKING ONTO BRAKE SHOES NEED INSTRUCTIONS ON HOW TO FIX
Jack up vehicle and support on stands. Remove wheels. Remove differential cover . Locate and remove lock pin that holds cross shaft in. Slide cross shaft out. Push axle inward to release axle c clip. Remove axle and pry out old seal. Install new seal with proper tool.Add some lube to the seal lip to aid axle intallation. Revese removal procedure. This is for a "c" type axle.
Another type has 4 nuts attaching a retainer plate to the backing plate behind the axle flange. In this case the 4 nuts are removed and the axle will come out. This may require a little effort. I think that you have a "c" type axle in your vehicle. Hope this helps. Moe

SOURCE: right rear axle seal leaks
If only your axle seals are leaking then just remove one axel at a time. Take it to an automotive machine shop where they will press of the old seals bearings and reatainer and press on a new seal barring and reatainer all greased up and ready to slide back into place. No need to replace the whole axle for a leaky seal. Once this is done with both sides ( assuming both sides are leaking) refil the differential so the oil just starts to ooze out of the fill hole and replace the cap. Presto you are good to go. Also an important note. Make sure sure rear breaks are not soaked in 90W oil. This will impede your breaking ability and cause a dangerous situation. If the break pads are soaked they will most likely need to be replaced.
