SOURCE: Rear end seal leak
You must be refering to the side seals. common problem. the actual problem with those rear ends is the air breather, which cloggs up and that's when your seals blow out, because the pressure in the rear end has nowhere to go and so your seals get blown out. I just did a set on Monday. Anywho, you will need some specialty tools for this. You will need to remove both rear brake assemblys (rotors, calipers). Than look on the other side of the backing plate, there you will see 4 big nuts that hold the backing plate on the axle tube (rear end). Remove those 4 nuts and that's where specialty tools become usefull. You will need a slide hammer. You need to attach the slide hammer onto the axle right by the studs. Use factory whel nuts to attach. Remove axle out of the housing with few good slides of the slide hammer. Once the axle is out, you need to remove the snapp ring, then cut the colar off and remove colar, then remove the old bearing and thats where the seal is. Big help doing this job is a pneumatic air hammer, which helps you remove the stuff off the axle shaft and the slide hammer to remove the axles out. You will need 2 seals, 2 bearings and 2 collars. You may also need the plates with the studs, which had the big nuts, that you removed in first steps of this repair. Kind of a job for someone that has been working on cars and has the tools to do it. Good luck. Oh ya, change the breather and the fluid in the rear end.

SOURCE: Rear Axle Leak
if it is the seal, you will have to remove the caliper and rotor, remove the differential cover and remove the bolt and pin inside the diff carrier housing. push in the axle and remove the axle clip and pull out the axle use a seal puller or prybar to remove seal reverse the steps to assemble

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.

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

Not hard to do. You need to remove the drive shaft, to get to the nut that holds the rear yoke from the differential. Once the rear yoke has been removed, you can replace the O ring seal from the differential by using a screw driver to pry out the old seal. Try not to damage it to much so you can use it to help tap in the new seal. Once the seal is out place the new seal in place by hand and then place the old old seal on it and tap in the new seal with a small hammer. Take care to ensure that the new seal goes in straight and place some grease on the seal before you place the yoke back in to place. Tighten up the yoke nut and you may want to replace the U joint at this time too since it's off the truck. Once everything it back together, check the differential oil level and top off. Good luck and hope this helps, you can get the parts at Auto Zone and they can also give you the step by step instructions to getting the job done with common tools. The hardest part that i can see you having is the removal of the yoke nut, the job takes about an hour to do so if your going to have a garage to the job the most would be 1.5 hours but should take them about 30 min to do.
