Well, Im done with my atlas install...Almost. Last night all i needed to do was install my drive shafts and I could drive it. As it turns out the rear flage on my atlas is a non cv (1310) style instead of the cv style that I require. I ran out to my local 4x4 shop and got the cv style for the atlas, but the seal behind the flage is too big. After looking at the 2 flanges side by side, it appears as if the non cv flange has a larger exterior dia. than the cv flange. I guess I need a larger cv style flange or a larger seal. The Seal that is in the unit right now has a number SR 21164. Anybody have this problem before?
