I have a set of 3.73s in the rear. Was done correctly. Backlash
was like perfect. Have a slight noise on accel ( wind up ). I have
heard that Richmond gears tend to be noisy anyways? Is this true? Also, break in period has been over 500 miles now. Still
noisy. Not loud, just noisy on accel. I also have the heavy duty
SLP zexel torsion diff. Does that make any difference?

How come my sig does not show up on replies??????

richmonds tend to make more noise than other gears because of the way they machine the teeth into the gears for more strength,

nolanr0413

yeah , i had richmond gears , they sucked, they got sent back, the company never asked me if i minded, and they were loud and i minded. so i had to send the whole pumpkin back and i got new gears. I also had 4.10s so it didnt make it any better.

Camaro_nut

If it's for more strength, then I don't mind! I would rather
have a quality gear set and do it's job, than have quieter
gears that are less quality. I know that Richmond is very
popular for their gear sets and transmissions. So, I can't
see that they would be making cheap parts.

Thanks for the info.

My friend had the Richmond 4.10s put in his 98 Trans Am.
I went for a ride in it after the break in period, and they
still made some noise. But, after a few weeks of hard
driving, he snapped the pinion gear. Put back in the
original 3.23s. or 3.42s. I know it was not the gears,
but the driving. He kills his car.

Richmonds are noisy POS's. Well they work fine but your always second guessing your work because of the noise. If anyone comes around the shop needing diff work done I wont even give them a richmond option.

Camaro_nut

Ah well, I will take the chance with them. If they break,
then the Moser 12 bolt wil just be taking it's place.


But, I can always try the SLP or GM gears.

if i was installing gears in street cars where 99% of the owner/drivers didn't know a whole lot i'd never do richmonds either because of the complaints about noise.

FWIW, when I got my Richmond 3:73s, there was a disclaimer sheet in the box stating that the gears might whine.

i have 3.73s and a SLP take off posi and i get a pretty loud whine, loudest at about 50MPH. Ive had them for about a year now and they are still just as loud but im getting used to it. Not so bad on the freeway and crusing. It just sucks when i have girl in the car and there like "what the hell is that noise, is your car gonna break" LOL

SSC

Thats when say, gee I better uh pull over and check things out.

I always heard richmonds whine too... i have a set sitting here i picked up from somone who didnt want them.. 3.73s..

but now im curious. just how LOUD is this whine? is it louder than a blower whine? is it like a gear drive whine? is it like a power steering pump low on fluid whine? is it louder than the engine with open exhaust and healthy cam whine?

So What whines more, the gears or you people? I can't hear my gears over my exhaust, blower, etc.

I busted the pinion gear on my Richmond gear set too. I broke the ring gear on the Competition Gear and Factory sets......

After a few thousand they quiet down quite a bit.....

PhilM

hate to be different but my richmonds are quiet..and they were in before the loud exhaust and I never heard them.

Camaro_nut

It's definitely NOT loud like a blower/supercharger or anything
like that! It's just a WIND up ( gear reduction) type noise at
30mph-up on accel only. That's what I get. I know for a
fact that it's not the installation either. I had mine done
with the help of a pro. master tech. Then my buddy's
98 T/A had his done around the same time with the help
of a different tech in our shop. Both were Richmond brand
gear sets. One is 3.73s, the other is 4.10s. Both make the
same exact noise. But his blew apart shortly after. Like
within a few weeks. Of course, his had 345rwhp LS1.
I had only like 130rwhp at best! He also drives like his
gas pedal is an on/off switch, but, there's nothing wrong
with that, just not ALL the time!


I am not whining about it either. I just want to know about
these gears. I only had put on about 1,000 or so miles,
so maybe they will get quieter. Even if they don't, my custom
7 speaker system with a brand new V8 with Flowmaster
will be louder than the rear anyways! :rockon:

Captain C

Gee, I drive like your buddy... glad you think it's ok!!!!! I have 3.42's in mine if that makes any difference. Due to a lack of traction in first gear (set up for handling, not dragging) I usually break things when I hit 2nd gear......

Ive got Richmond 3.73's they are supposed to whine, I know exactly what your talking about. I read somewhere on why aftermarket gears whine was because they have a higher nickel content then factory which makes them stronger but causes whine. I know I read it on a gear site or rear end site.

As far as breakage, I broke 2 sets becuase they were installed incorrectly, once by a performance shop and the next by a GM dealership! I actually had to get them put in at a DODGE dealership to get it done right!WTF! For what I paid for all that BS I could have bought a whole freakin rear end! Thats when I started to do as much as possible myself or with help from someone with experience!

What did both dealerships do that was wrong? The gears haev the freaking specs written on them. You set the depth, then set the backlash. wtf?

They didnt shim them properly and they whined bad and the service manager told me that this was normal, Iknew it was normal for SOME whine but this was bad. Also they didnt change out the spider gears from the previous screw up so they were already damaged. After I broke 2 teeth off the ring gear and a couple of the pinion they said "oh you need new spider gears", I took it to a friend at the Dodge dealer who had his tech friends do a very good job. It was a bunch of ****. The first place was just a performance shop and they did a rush job on it and also didnt get it all properly installed either.

SSC

Sorry LUV, that site is full of . The aftermarket gears mostly richmond are cut for more contact, some racing gears are cut for an agressive contact that eats the gears up in less then a season and it considered normal. the more contact the more noise.

LUVmy92

Ok your probably right but I do belive that they use more nickel in them then factory for strength but it probably has nothing to do with the whine, its been awhile since I read it. Hell Im probably wrong on that too!
