I have an 04 and changed out the rear differential cober this weekend. I have done a little towing over the 1st year of having this truck. Most of the time i was just towing a tent trailer with a quad in the back, but once i towed a travel trailer that was around 3500 empty. The oil that came out was pretty grusome. It was dark grey in color and smelled. The gears all looked ok though. Replaced with 75-140 mobil 1. My question is, the new 05 cover does not come with a bracket for the emergency brake cable. Can i get some help as to what others have done, or what Nissan does on the 05 with the E-Brake cable?
