Hello everyone I am new to the forum and hoping for a bit of help! I picked up a 1999 Chevy Suburban LT after a bad accident Christmas eve that totalled our 03 GMC Envoy XL. I noticed when I bought it that the rear seal where the drive line attaches to the front diff was leaking a bit. After making the purchase I went right down and bought a new pionion seal and replacement fluid. I got it all apart and noticed inside under the seal there was a small section of the inside metal lip missing right at the bottom. I was guessing this is why it was leaking but decided to install the new seal and keep my fingers crossed. Well of course it still leaks. My question is has anyone else had this problem? Is there an easy fix or am I going to have to replace the front diff? Thanks for any and all help!
