noisy differential 1981 C3


There is a slight whine from the differential whilst driving. It is not too noisy at present but it can only get worse.
I have not yet had the oil level checked. Is it worth renewing the oil plus the GM additive in the hope that this will quieten things down or would I be better to go for a replacement diff?'
If so, are there companies in UK which do them on exchange or do I have to send my own diff off for overhaul. Or will I have to buy a new diff?
As always, I appreciate the advice received.

Re: noisy differential 1981 C3


How "slight"? . Is it at certain speeds? "They all do that sir" to an extent, and if it is just gear whine, it's not something I'd worry about.

What about other "symptoms". Does it leak at all? Any signs that the bearings may be aging?

Yes, pump out the fluid and replace with a good 80/90 gear oil and the proper GM additive - no substitute for that at all!

I wouldn't be rushing into a diff change unless I had to! And, I've had to! We went with a rebuild and while in the end it was great, it was not the best option and certainly not the cheapest! Assuming you're not planning on drag racing the car, a rebuilt diff would be the best, easiest and most cost efficient option! I think you'll find that the usual UK suppliers, would be able to set you up with one....

My diff was rebuilt by a guy who really knew what he was doing, and he had a real "game" with it - more damage than first thought, sub-standard parts, etc etc, so it's definitely not a job I'd recommend for an average home spanner wielder!
