Service bulletin review

Service catergorie-Driveline/Axle seals to correct fluid leaks (w/diff) 14-leaks

Subj:Release of new rear axle seals to correct fluid leaks

Models:1997-2004 Corvettes

This bulletin is being issued to inform dealers that new and improved rear seals have been released for service for the above listed vehicles

Use the new output shaft oil seal P/N 88996703 and the new differential side cover o-ring P/N 89047953 when correcting rear axle leaks

 

I believe this will give me enough reason to do the rear-end gear swap finally! "Hey, while your back there, here's a 3:90 gear..."

 

4.10 baby, all the way...

 

I've got a 4.10 rear end sitting in the garage waiting for a clutch to go with it. I bought it used and it doesnt look like it was leaking before.

Think I should throw these new seals on it just in case?

What does everyone think of the 4:10? I've talked to many people around Atlanta and overall, the 3:90 seems to give great results.

 

I had 4.10 in my 94 TA M6 and liked them a lot. It made 6th gear more usable. In my C5 they will be slightly less agressive since I'm using a 1" taller tire than I had in that car.
