Need some quiet gears
I have a Moser 12-bolt with aftermarket 3.90 gears......they are noisy as hell (or else I'm just too picky), so I'm thinking of either going to some OEM gears.....but then I'm limited to a 4 series gear ratio, or else maybe I go to a different brand of after market 3.90 that are quieter.
I spoke briefly with Cliff Ruggles and he feels like a 4.10 would be too much gear for my combo....... Dunno what to do.......Cliff says he has had best luck with US Gear, but I don't think that brand is still made in the USA.....quality has probably degraded since then...... What brand have you guys had good luck with?

I've got a set of 3:90's at home, still in plastic, but don't know the brand or the series they are. They are for a 12 bolt

I havent had noisey Richmonds but an old "Zoom" set I had whined no matter how you set them up. Are you sure the noise isnt other differential components?

I have Yukon 4.56's in my truck. Been in there 3 years & many miles. Did the 2007 Power Tour right after I installed my setup. Did 2800 miles in 8 days. Never a peep. I'm critical myself when it comes to noises, too. My GTO has plenty
 Not sure what you mean by noisy. Maybe the rear diff isn't set up correctly (tolerences). Could be a bad carrier bearing or even a pinion bearing. Even an axle bearing could be noisy. Maybe give us a little more info IE when they are noisy - off/on the throttle, cold/hot, etc.

Try Motive gear. They have them in 3:90 I have set up many 12 bolts with these gears & are not noisy. They are a good gear set & I think you will like them very much. They are around $210.00 for the set at Summit

Then you need to check the set up on them as they have been very quiet for the people I have done rearends for. Do they make more noise under load or on the coast side of the gear?

i have also has good luck with the motive stuff.
they have a line called "stock performance" it is made from the same material that their other gears are made from but the surface finish is much better. i don't know if they have that ratio for that series carrier but you should check them out.

Most noise or lack of it is based on how the gears are "lapped" together during the production process. Ford's Sterling Axle plant used to make very quiet 9" Ford 3.90
gears. The GM stuff, who knows. probably if it has all of the teeth on the pinion and ring gear during the process they call it good. Tom Vaught

That is a very TRUE statement. I said nothing about Moser gears in 9" ford rears, US Gears in 9" ford rears, Richmond gears in 9" Ford rears.. I recently bought a set of 9" FACTORY ford gears from B-Man. I questioned him about whether he actually was selling a true Ford made gear set. (HE WAS). I bought the gears. The vast majority of the gear manufacturers do not hold the same standards for noise, strength, wear, etc as an OEM (Ford, GM, etc). The fact that you had a 9" rear under a GM 3rd generation Camaro says a lot, LOL! A Quote by Jimmy Keen when GM "Super Street" racers complained about him using a 2 speed Powerglide trans in his Mustang: " I will run a Ford transmission IF you put the 10 & 12 bolt GM rears back into your cars." END OF DISCUSSION. Tom Vaught ps The TOPIC was about QUIET GEARS and Ford does a great JOB with quiet gears in many cases.

You need to pull it apart and have a look, they might be setup wrong. Ive used summit, richmond, and motive brand gears and they all were quiet.

You are right as i did read what you posted wrong.....and one of these days i'll win a "conversation" with one of you two....lol.....but until then..... My daddy worked for Ford and my Buddy had the Ford rear in his 3rd gen so that says alot about them.... I sir like Pontiacs so that speaks volumes about me.......lol My buddy's rear had other "issues" besides the gear set and once corrected was as quiet as a church mouse with the gears it was supplied with. I will stand by my original post as there are alot of "issues" i have heard of with rearends reagardless of make from certain compaines........
