[C5-Tech] Diff Leak Question
I ran a search on this topic and I just want to check on some specifics.
I have the typical leak coming from the 8 O'clock position on the left side cover of the differential. I have a '99 6 spd. with 13,000 miles. It has been on the track a few times and is driven like a Corvette was meant to be driven :D
You have said that the best repair is to replace the cover due to casting problems with the original covers. Use a new Oring and apply anerobic sealer as well.
The part # I have for the new cover is 12458145. Is this cover the correct one to repair this problem? The part # for the Oring is 12457739 and the axle seal # is 12369460.
This appers to be a do it yourself type of job for an experienced mechanic after reading through the shop manual. Any tricks or pointers that I should be aware of? Do you know what the flat rate time is for this job? Anything else I should look for while I am in there?
Thanks for your help.:cheers:

I think its a long job... I think techs get around 6 labor hours for it. They keep my car overnight and gave me rental, they usually only do that for 6+ hour jobs I think.
If your doing it yourself for whatever reason, you may be able to just replace the O-ring and used C5-tech's method for sealing it. Its usually the o-ring that flats in most cases I believe.

Re: [C5-Tech] Diff Leak Question (Bob C)
Out of about the 40 that I have resealed,I have only had to replace 1 side cover for a reoccuring leak.Most cases,it is simply the o-ring seal flattening out that causes the leak.
Warranty time is only about 2.5 hours,with customer pay (chilton) time around 4.0 hours...
The job is pretty much straight foward.You will have to double nut the stud on the cover that goes through the trans to remove the cover,and that is the only PITA...Apply some anti-seize to the axle splines when you have it out to prevent the common popping noise from the axle shaft...

Posted in another thread, but you may even want to have the dealer check it. They checked mine and it was a manufacturer defect and couldn't be resealed and expected to last...so, I got a new one (warranty). Just a thought...good luck, doug :flag

The best way to remove a stud without damage to the threads is to put two nuts on the stud, tighten them against each other and then use the one closest to the base of the stud to loosen the stud out of the object it is in.

Re: [C5-Tech] Diff Leak Question (ersatz928)
Because there is a stud that goes into the side cover for mounting the transmission. In order to remove the cover, the stud will have to be removed along with the bolts that hold the cover in place.
