How many miles did you get out of it before you discovered that? I've got a few thousand miles on mine, maybe I need to remove that cover?
Lator.....
I'm guessing about 3000 miles. The Rubicon (MCR4) and all the other trail rides. A lot of hwy speeds plus it got water in it twice with syntetic oil.
Looks like the pinnion is ok and all I need to do is put new bearings in it.
