i'll start off by saying i have a 10 bolt with 4.10 gears and a m6. i've beat the on the car pretty good waiting for the rear end to go. it took about 3 months of beating on it and tonight something went lol. i was at about 5k in 1st and shifted into second when i heard a POP followed by griding and what seemed to be something flopping around. first thing i thought of was i broke a u joint but as soon as i touched the brakes the noise went away but i pulled off anyways to look. i seen nothing wrong so i decided to limp it home since i was onlt about a mile away. i pulled out and there were not weird noises until i came to a hill and there went the beating/flopping around sound. do you guys thing i just broke a tooth or what? i plan on pulling the cover off tomorrow

Are you sure it's in the rear end? can you feel the "beating/flopping" sound in your floor pan? Could be a broken torque arm mount. Just seems weird that it completely goes away at some points. Leads me to believe it isn't in the differential at all.

if it was the diff, it would be a distinct clicking, and jerking or the rear end. it would probably not go away. i would also check your TA

when you put on the brakes the torque arm wants to go down(so back into place). when you get on the gas it wants to go up (unto your floor pan) deff check the TA

i'll go check that right now.

well i looked but nothing seemed loose or broken.

i backed down my driveway, which is pretty steep, and it pulled back up it but the griding noise is awful. i backed back down and turned around and backed up the driveway and it was like nothing at all was wrong.. any more ideas?

Spider gears is my bet.

Spider gears is my bet.

Agree 100%. That was the same exact scenario when I broke my 10 bolt spider gears. A hard 1-2 powershift and bang. I wasnt able to get just the spider gears for the diff. Had to get a new casing that fit the gears. Broke that too. Hence, the 9". If your gonna keep the 10 bolt, upgrade to something stronger like a detroit locker or even a spool. Only way to really make a 10 bolt last any amount of time. Good luck with the repairs.

I would hardly call blowing a 10 bolt bad luck, it is more like a forced opportunity!

Took the words right out of my mouth:)

Perfectly normal 10 bolt.
