The service manual says to use a moly grease, the folks on this thread are saying to use the Red N Tacky, but a few mechanic friends of mine and the mechanic down at our local Artic Cat dealer told me to put the seal in dry, don't grease the seal edge or housing because it can pop out. So..... can someone tell me if there's a secret reason to use the Red N Tacky (or any grease for that matter) that my dealer hasn't yet heard about? They did say to grease the inside of the seal so at least we are on the same page there.

Don't grease the edges of the seal. It's a pressure fit and it I'll pop out with grease on it. You fill the cavity in the diff side cover and the back side of the seal. I've been using red and tacky for years and wouldn't use anything else. Just my opinion.

So you're saying to keep the outer edge of the seal dry as well as the housing where it slides in? But to grease the back of the seal. The OP's pics and instructions show him greasing the whole outer seal edge and the housing sides where the seal slides in. Well I guess I'll have to go with the majority and pound it in dry I guess. I really don't want it o pop out.

a bit late in the game to pipe up but I smudge a fine coat of diff oil on the outside to make it slip in easier, and its never been an issue with popping out. and I don't use a screwdriver, to remove it, the sharp edges can easily scratch the insides. anything blunt that will pry is best, such as a tool used for popping tire tubes off or an old worn out coal chisel.
