SOURCE: Rear Axle Removal
if you are talking about the axle seals, 1.REMOVE THE WHEELS.2. REMOVE THE DIFF COVER(slowly)3.REMOVE THE BRAKE CALIPER ASSEMBLY.4.REMOVE THE 8MM PIN IN THE DIFF CARRIER. 5.TURN CARRIER AND REMOVE THE LARGE PIN.6. FIRMLY HIT IN THE AXLE, A SMALL RETAINING C CLIP WILL FALL INTO THE DIFF HOUSING. DO THE SAME WITH THE OTHER SIDE. ( be careful if you have rear speed sensors remove it when you remove the brake calipers . you will break it when you are pushing in the axles.)7.pull axles and replace seals

It is fairly easy to do. remove rear wheels and brake drums, remove the differential cover, rotate the diff to access the diff pin bolt and remove, remove pin, push axles inward and remove c clips, slide out axles and replace seals. reverse procedure

You are Talking about the Main Cover on the Rear of the Rear end Correct???? If so, This is Just a Gasket and is Very easy to replace. The Gasket is Simply Worn out.

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.

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
