Hi,
I have two 9 bolt rear ends. And there was the same problem in both of them.
Left wheel seal was leaking. My question is if there are any kind of trick (or secret knowledge) or just my bad luck? The first one was used a longer time before started to leak. The second one was rebuild with all new seals and bearings. And after about 2k miles the left wheel seal started to leak too.
Does anybody know why left and right seals are different? In fact, the right one seems to be stronger than the left.
Any suggestions?
