Re: new 3.73's installed and.. My factory 3.23's are the same way, hurts nothing.
I have heard that the GM gears are quieter, but I have no experience with different aftermarket gears

Re: new 3.73's installed and.. Mine do the same thing. I also have motive gears, but its not the gears to blame but the set-up. I hear some guys say theirs are silent, but ive had several set-up on my 97 and my 00 and they all have made some noise. Even the gears I bought from my Chevy dealer.I am very happy with the track gains though!

new 3.73's installed and.. now i've noticed that they are beginning to make alittle noise. this happens exactly at 50-60 mph and it makes a humming sound like that made by offroad tires. (i hope that's a good description) there is no noise below or above the indicated speeds and also when i go into reverse and back up, the sound is similar to that import geary sound when they back up. know what i mean? i think i may have compromised sound for price. the gear brand is 'motive'. other than that, i do not experience grinding or any other type of unusual noises. i am otherwise happy with them and i do like the little bit of grunt gained from them. any input is appreciated.

Re: new 3.73's installed and.. Not unusual at all with these cars. Even my stock 3.42s in my SS make a little noise.
Nothing wrong with Motive gears. They make gears for GM too ya know.
It'll get a bit worse as you thrash on it and then should level out.

Re: new 3.73's installed and.. You don't know whine until you put Richmond Gears in your rear end
. Mine WHINE!!!! Man do they whine. We we are experiencing is the result of the smaller pinion spinning through the rear end fluid. I have the added problem that the cut on Richmonds is such that they have a VERY small backlash (very tight so they make a lot of noise). Just be happy that you didn't get a bad setup and enjoy the added performance (I know I do <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" /> )
