Stock 10 bolt

[Silver Streak]

Ok folks, for those that don't know:

GM made the 12 bolt, so called because it uses 12 bolts to hold the ring gear to the carrier. It uses a ring gear of 8-7/8" diameter. It's the lightest duty one but folks like it because it's originally a GM part. They put it behind all the high performance GM cars of the 60's. While GM never put a 12 bolt into a car with a torque arm (no direct replacement) MWC (Moser) makes an aftermarket version that bolts in.

Ford makes the 9", so called because the ring gear is 9" in diameter. It'll handle more torque than the 12 bolt due to the larger bearing surface of the pinion bearing. This is what Ford used behind all of their high performance cars in the 60's. It also uses more torque to turn so greater driveline loss. Aftermarket makes bolt in versions for us.

Dana makes the Dana 60 which uses a 9-3/8" diameter ring gear. This is what you want for that 2500hp monster you always wanted to build. Afterall, Mother Mopar put them behind the 426 Hemi with a 4-speed, so.... Creates greater driveline loss than a 12 bolt or 9" but it's the ultimate in reliability. Aftermarket makes one for our cars too but it's more expensive also.

Any questions?

10 bolts can be noisy, many if not most are. GM makes/recommends an additive but I forget the name that will help quiet things down in your 10 bolt.. The aditive can usually be puchased @ any auto parts store...

i added the aditive and it still makes that noise..
we had to replace the oil at 500 miles to double check everithin was fine inside the pumpkin ..

He has 3.73's in there now. I can think of many or most stock 10's that are quite. With 3.73's I would wonder about the gear setup and backlash..

So you think it's a crush sleeve or bearing issue or both? Curious.

hmm It may be inside the trany.. More curious..

Not saying he did bad work.. But $100 for a gear change is well cheap.. Anyone can swap gears. Not all can set the gears up correctly.

i dnt think he did a bad job,,, i think the problm is the gears.. idk what brand they are,,
the whole job came less than $400 dollars any other shop was chargin 4800 Just for labor..
but nxt time i get the 4,10s ill make sure i get somethin is better quality

it comes from the bk.. i think is the rear end..
some mechanics say it could be normal.. but i just dnt like that noise,, long trips.. it gets on my nerves,,

I could be the shims (to few to many) between pinion and the rear bearing,

Hmm... I think thats all I got..

[Smittro]

Oohh I did'nt even think about the pinion shims..

[Z28Thunder]

Hmm... I think thats all I got..

You have more...

[Z28Thunder]

Oohh I did'nt even think about the pinion shims..

If you can TALK in a performance car... you're missing a few cylinders.. or you're in a Mustang.....
