Question about 2002 Chevrolet Tahoe
Not that difficult, raise and support the rear of the truck and remove the wheels. Might as well replace both sides so you know you have new seals, remove the differential cover and drain the fluid. Once differential is opened and cleaned , remove the axle "C" clip that hold the axle in place and slide the axle out. Once the axle is out remove the wheel seal and clean around the area. This would be a good time to replace the wheel bearing too since you have access to them and there not that expensive. Install the new bearing and seal, note make sure you oiled the bearing and seal before installing it back and take care when installing the axle back in and "C: clip. Use RTV silicon gasket maker to seal the differential cover and wheels back on and lower. If your lazy like i am, you can drain the differential fluid and replace it with a 50/50 mix with gear oil and Lucas engine oil additives. That may stop the leak and get you a few more miles. You gear oil is 75W-90 and the capacity is 2.6 liters and 3.6 liters if you have the 11.50 Ring gear. Good luck and hope this helps.

The rear axle shaft seals are a little bit of a job but not impossible.
I would replace both right and left as long as you have to replace one of them.
You will have to remove the rear differential cover and drain the grease.
Next, depending if you have a limited slip or conventional differential, you will have to remove the spider or limited slip unit.
"C" clips located on the end of the axle shafts are then removed. The axles can be removed from the axle housings and the seals can be replaced. They are located in the axle housing.

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

You don't have to remove the whole diff to change the seals, but you will have to seperate it where the shaft meets the carrier housing. There is a clip holding the passenger axle shaft in place that you have to remove to change the seal. The drivers side axle stub can be removed with a little force as there is a spring clip holding that side in.

SOURCE: Rear Axle Leak
It might be the bearings that failed and letting the axle rest on the seal. Its a common problem for these cars. I've replaced mine and it did it again so now im replacing the rear end.

ok then here is the procedure
1 take off the axle nut
2 on the lower control arm you will find a large nut and bolt i belive the nut is a 21mm and the bolt side is an 18mm. this bolt is the one at the knuckle near the brakes. remove it
3 you will need to pull the knuckle out of the way or a helper to pull the knuckle out of the way so you can slip the axle out of the knuckle.( its a tight fit but there is room to slip it out.)
4 use a pry bar to pop the axle free of the diff. hosing its held in by a spring clip make sure the clip comes out with the axle if it gets stuck inside you will have to fish it out.
5 use a pry bar or screwdriver to pry seal out of housing then use a flat object that contacts the entire rim of the new seal so it can evenly be installed with out getting smashed and tap it in with a hammer. ( a good trick here is to use some grease and pack it into the new seal where the spring is this will prevent the spring from being shocked out of the seal during instalation . the spring keeps tension on the rubber in the seal so it stays tight to the shaft it is sealing.)
6 then revers the above steps. also make sure you are using the right gear lube it will most likely be 75w-140 but make sure you check your owners manual will tell you if it doesnt say on the diff cover. you can cause a lot of damage if you put in the wrong thing. and make sure you feel the axle spring clip snap into place.
as a note there are two types of axle seals that are used on these so if the new seal looks different than the old seal then the folliowing will be important to you.the seals on these have been redesigned so if you axle has what looks like a cup or dust cover pressed onto the shaft where it goes into the diff the new style does not use this and it will prevent the axle form going in all the way so the spring clip will not lock in and you will have a leak. so you will have to remove it and install the axle without it.
