Its time to change the rear end fluid, so I was wondering if anyone had any suggestions for which brand of fluid? If I remember correctly, Royal Purple makes a fluid that already has the additive in it, so would this be a good choice? I was also looking at the stock differential cover and it looks kinda ugly lol so does anyone have any opinions on the AAM cast aluminum one from SLP? http://www.slponline.com/view_produc...04&BIG=65004-1

I used Red Line 75w90. It also has the additive in it. I like it a lot, seemed to quiet the rear down a little bit. My cover was ugly also, covered in rust, so I painted it.

Thanks, I'll look into the Red Line.
