Yes, you bought Richmond gears. Known for being noisy.

howl on decel is usually ring and pinion noise

You're not supposed to reuse the crush collar, it's a
disposable piece and you crush a new one to get the
setup fitted to the new pinion. Then you shim the
chunk for contact pattern. If you take it apart again
you might consider a hard pinion spacer & shim kit,
that is reusable and won't get beaten down with age
and abuse.

I guess I'm curious as to why you went from 3.23's to 3.42's. Not much of a difference for the price.

no sorry i used the new crush collar and all new bearings. my b/l .008 and i have the stock size shim in pinion. on Acell its ok, slight i mean slight whine. but on decell it howls like a mad dog. when up on the lift and put in gear the rear has a howl that comes and goes, also when driving it howls as u give a slight amount of throttle.

Can't speak for him, but I did the same ratio swap on mine
(but stock GM gears) when I went to the T-2R since that
was a total pull-apart deal anyway.
