I'm back, I replaced my rear pinion seal about a month ago, it started leaking again. I guess it seemed to easy. I simply removed and replaced, didn't use synthetic ( I know) found this out later. Didn't torque to any requirement, don't have the spec's if required. Have been reading on here about crush collar, have no idea what that is? I know you may think "What the hell is he doing"?, but can someone give me some good advice when I go to replace it again, or do I need to take it to the shop??? Please direct me in the right direction. Thanks all.
