83SD rear end
I discovered a leak around the rear end of my car. I thought it was a fuel leak but when I cleaned it up it looks like it oil leaking out of the rubber boot at the rear end on the drivers side. The rubber is cracked. Does the oil from the rear end lube ( looks like a cv joint) this area or is it a leaking seal allowing oil into this area?
What is the best way to repair this. Can you order rebuilt half shafts and install them at home? Need any special tools? Can you or should you replace just the rubber boot? Thanks, Ken

In the manual the procedure to do this job is 25 pages long, and that does not include the possibility of needing to rebuild the joints, do you know how long the problem has existed? hopefully the joint is not full of debris, the manual also lists special tools to do this, you would be better off doing an r&r of the axle (DIY) as a hole rather than replace the boots, used ones cost about $100, rebuilt ones about $200 and new cost $300 or more, just doing the boots cost about $100 if you find someone with the correct tools, there is a possible alternative, I saw that a company named Cosmos International makes a split boot kit for the w126 and other Mercedes models. Here is there ph# 1-800-221-2668 I do not know if the number is still correct, give it a try.

It just started leaking.
So is it normal for oil to get inside the boot?
Both boots at the differential are cracking.
Most cv joints are greased inside and sealed with a boot.
I was thinking that there should be a seal that keeps the differential oil in the differential and out of the boot? Thanks, Ken
