Differential/gearbox rebuilders

[a91_formula]

Looking for recommendations for someone who can rebuild or re-set up a GM 10-bolt limited slip diff.

The current rear gears were installed and set up by a company twice but each time they have a slight whine, very common with Richmond gears we know but we want it better.

Thanks

Have you tried Websters?

Webster racing did my 10-Bolt.

Hauser did Chris MoPar axle IIRC.

if all you have is a slight whine, i'd say they are spot on..(though its impossible to say without hearing them)

Richmonds are usually more in the category of 'howl like f**k' - they are strong, because they are a coarse pitch - this makes them inherently noisy.

My friend Jan in new jersey has Richmond 4:11 in her ford 9" and they are such a coarse pattern that not only do they howl, they actually vibrate on the over run. his is apparently perfectly normal.
