I was under my truck bed adding some friction modifiers into my rearend, when I noticed oil leak on inner side of the back wheels (both side). Now about a year ago, I had my clutchpack redone due to defective clutchpack problem. I believe this is the cause of that leak, when they worked on it. The oil leak appears from the little rubber cap on the under inner side of the wheel. Am I wrong on my assumption or is there other cause of this problem? Has anyone else experience this? I am planning on taking it back to the dealer soon.

 

Sounds like the axle seals might be leaking. Yeap, take it back.

 

Take it back!
