If you have modified your truck so that the drive shaft orientation has been modified from stock, you are probably going to ruin what ever seal you put in unless you modify your drive shaft to compensate for whatever slamming you do.

You where so right Neptune! The previous owner of the truck used the wrong seal. I picked up the new seal tonight(had to order it) and it was a totally different seal........
