I just finished my ball joints so my truck is still currently apart. I know that my front diff is leaking and I am going to assume it is the seals at each axle end.

My only questions is if anyone has any pictures or advice when replacing the seals on the front diff ?

 

i just replaced mine. idk about parts places down there but no one had it and i had to order it from GM. as far as replacing it, its easy first i put the new seal in the freezer, then. pull the old one out (i ended up using a big flathead screwdriver) take the new one out of the freezer, put a little extra grease on the rubber seal just for a little extra insurance and pop it in the there.
