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.
