Isn't that problem the seal replacement? Is it hard to do? Do you haveto tear into the whole thing, or do it from the outside?
It's easy to do from the outside. The out _front_ side. Getting access to the front side is what costs $500, it's a bunch of labor. It's very possible to DIY, though. I have. You need tall jack stands and a floor jack, and a good free weekend and a place to work. -- Jim
