Default Leaking Rear End Seals!

I know that this is a common problem, but I have gone through this several times now! Lucky I am still on my extended warranty, but I am worried that it is coming to an end and that I may have a more serious problem! All comments and suggestions welcome! Thanks....

My guess is that you have a BROKEN BELLVELLE spring which will allow that output shaft to have some additional slop. Jack up one wheel and ATTEMPT to rotate it. (TRANS in N and parking brake off) IF,, all is well inside the rearend, you will have a VERY DIFFICULT time rotating that wheel. If the clutch disk are weak/worn and or that spring is broken. it will be easy to rotate;

Heres what a broken one looks like:






Here are two EXCELLENT post on whats inside the differential and how to up grade it with C6 ZO6 Parts:

- C5, ragtopws6 , Upgrading your C5 rear with C6 Z06 guts, : http://forums.corvetteforum.com/c5-g...-z06-guts.html

- C5, Its_Go_Time, Output Shaft Install - Left and Right: http://forums.corvetteforum.com/c5-t...post1573407966

If the wheel rotates easily,, make them service the rearend Theres a SPEC and a test in the service manual that they can perform to tell if its bad.

Do the vent TSB ... I put an open vent/filter on my differential and my oil leakage stopped. The Micky Mouse vent on these differentials stick, and pressure builds up inside the differential than makes the vent puke and/or the seals leak.

Very interesting, I will check this before I go back to the stealership! Still under warranty for the next two months but rather fix what I can myself.
