Advice needed----VERY SMALL leak from rear.....

Hi all, over the past couple of weeks I have noticed a very VERY small (dime size or even smaller) drip of what appears to be rear diff. fluid under my car after it sits awhile.

I took it to local transmission shop and they put it on rack and looked at it and called it a "SEEP" said that I shouldn't be losing enough fluid to hurt anything, just have it checked everytime I have oil changed and watch for any big drops to appear.

Is this good advice or should I get a 2nd opinion, & how much would a leak on a rear diff be to fix?

Thanks,
Jamey

Rear end leaks are a common problem on some C5's. Heres a pretty good post that talks about it:

Sounds like a seriously good excuse to slap some 4.10s in! No sense wasting all that labor $ just to fix a leak without getting some additional benefit from it!

This happened on mine after 20K miles. There is a service bulletin (which had been posted herein) about it. If under warranty you should be covered.

Before you take it in, try draining a small amount of oil (1/4-1/2 cup) out of the diff. It could be leaking out of the breather under hard acceleration. That was my problem anyway.
