Default Dilema

I am trading exhaust with a forum member. So I lifted the Vette and I noticed a level 2 leak coming from my diff. Level 2 being that its starting to form a drop on the diff itself, but haven't seen anything on the floor yet.

It is a C5 ZO6 diff with upgraded clutch packs and hardened output shaft a nice diff. So should I rebuild it or should I go with a new RPM or such diff.

If you guys want pics I can post them tomorrow.

TIA guys

Verify where it's leaking from ... could just be the vent puking a little oil, which is common on these differentials.

Why rebuild if it may only need a seal?

Shes starting to get a little whine with the push of the gas pedal so it might be that time.

Thanks for serving brother!

Clean it off and take her for a spin. Inspect after the drive. It will give you a very good idea where the leak originates from.

Your DIFF operates under a slight vacuum when cooling down. The vacuum helps keep the fluid in the diff. The vent at the top has a ball check that allows air OUT and none in:



Here are a couple of very cool post on the diff:


- C5, Its Go Time, Output Shaft Install - Left and Right : http://forums.corvetteforum.com/c5-t...post1573404441

- C5 RAGTOPWS6, Differential UP-Grade; http://forums.corvetteforum.com/c5-g...-z06-guts.html


If you need to replace a seal,, its in there!

It seems odd that it has one of the most common of C5 problems, but has a built rearend. Wouldn't the owner that had the rearend done, fix the all too familiar rear seal leak?

It's probably over filled and puking out the vent.
