It might be a pinion seal, but its hard to say. It only seems to leak on longer trips, or when im going 75 down the highway. I did find that the SOLID brand diff covers have a fill plug that is like 2" higher than the factory one, so I may drain out a little fluid and see what happens...






In other news, I got my new winch all mounted and set up yesterday. Its the Smittybilt 9500.
