Gears & Axles - Exploded 10 Bolt

I joined the ranks of a stock 10 bolt expolding at the track yesterday. Thank god I had AAA 200 mile towing. Even before I drove to the track I had a feeling this could be the day, I wasn't disappointed. It was 3 years in the making since the whining was getting louder & louder. Any recommendations out there on a replacement?? I drag race the car(98 T/A) about 3 - 4 times a year, 335 rwhp & something that will handle 1.6, 1.5 60ft's. I also have the Spohn Adjustable Torque Arm, I would like to continue to use that. I probably have 300 passes on this car, I guess I was lucky for a long time.Thanks

Cant go wrong with the strange dana S60!!!

There are a ton options out there so make sure to do plenty of looking to see what fits your budget, and your build. I have dealt with both Midwest Chassis and Performance as well as Moser. Both companies do a great job and could no doubt get you taken care of.

M6 or auto?

Auto, 3500 stall, Have a Yank SS4000 sitting here in case I want to get serious again..lol

Throw another 10 bolt in it. Auto car can get alot of passes on them. Unless you plan on throwing some serious cash at.

10 bolt=150$
moser= 2k +

I keep a spare 10 bolt in my shed. My current one i've been beating on for years and it doesn't even whine yet.

See? My point exactly

Thanks for the advice, I have actually had good luck with the stock 10 bolt. I will try to find one somewhere.

Mine whines.... lol

If your doing 335 rwhp and an A4, no real future HP mods...I wouldn't drop the coin.

Seems to me that the M6 and 400+ hp they don't last long at all. My third setup lasted 15k, just bought an S60. For me, I don't mind having the insurance.

Why do some stock 10b whine with gears and some dnt? My buddy T/A sounds like it has a whipple supercharger in the rear end lol... Was it not installed rite? Pinion depth off? Not long enough break in period? I need the answer. Makes men2nd guess putn in 4.10 in my M6

The 10b wasn't a bad axle in the leaf sprung suspension era. Now with torque arm mounted to the housing & more hp just puts enough twist on the housing...just doesn't hold up to much abuse.

True. My 10b in my Chevelle has held up since I've hda it. Then again I dnt pit it threw much lol.

Mine sounds like a whipple too after the 3.73 gear swap - immediately after installed with used gears - it doesn't mean it's gonna blow. If they are not set right this can happen too though. Mine were professionally installed and he told me this might happen with used gears. Something about backlash I believe.

I have a buddy with a Nova that is running low 13, high 12s (not bad for a mild 400 sbs at 5k ft of elevation) and does really well with his 10B. He also is running MT slicks.

10 bolts in the GM past were/are strong,don't compare/associate those with our puny 7.5/7.625 10 bolt.
GM 8.2 10 bolt 1964-1972
GM 8.5/8.625 10 bolt 1970-1996 also used on Buick 84-87 Grand National. Only 3/8" smaller than the 8.875 12 bolt

Good point, different size and design all together.

So with proper install. Perfect backlash. And new gears(with proper break in period) I should be good from and whine? I dnt want my car to sound like I have a Whipple unless I ACTUALLY have one! Lmao

Doubt it.

my rear in my 02 is howling and got a good groan now on decel.
i recently talked to a local shop about getting it rebuilt, the guy seemed sincere and said he's set up a few gm 7.5" and had them come out noisy and had a customer come back. he reworked them and even called GM tech support and was told it's a fact of life since the ring gear is so small... that's basically what i remember hearing on the phone. so take it for what it's worth.
I asked the guy about rebuilding mine and he said he could not guarantee it would not be quiet and recommended getting an aftermarket rear end with a bigger ring gear. so unless mine is something simple like an axle bearing, and i don't even feel like putting a $1 into it, gonna go with an S60 and new tq arm and try to swap it all out over the winter in my garage.
so there might be a 10-bolt complete rear for sale if anyone wants it.
