anybody heard of a heavy duty c bearing for a third gen? the stock one is junk. 70,000 miles am on the third one
I've never heard of a failure. My former '01 has 350k miles on the OEM, my former '06 had 230k on the OEM when I sold it. My '08 has 46k on it now.
Something is wrong with your differential housing or the way you use or maintain it.
I have seen a few... ..... not everybody uses their truck the same. Out here in the west,I see more failures with the 06 and the other years just wear out.
Is your truck lifted? I didn't see it in your signature.
