well fellas i did it again, i busted another axle. second one this year. anybody else have problems with GM 10 bolts breaking axles?? both of my breaks have been very WEIRD the first one broke right off at the hub, going down the straight away.the center was still there but the hub was on the wheel. last nights sheered off right behind the hub inside the tube. at least 5 people told me they aren't supposed to break in either one of those places. anybody else have this problem???? what can i do to strengthen this GM up??? i had been leading the race but fell back to third before the axle broke so it was heart break city when my wheel passed me.

One of the biggest problems is the axle bearings in a 10 bolt,especially the right side which is lacking oil during most of the race.

I have seen racers replace axle bearings in their 10 bolts twice during the race season,once at the beginnig and midway thru the season. I have also seen racers over fill the housings to insure oil gets to the right bearing.

Another bad part of racing is contact between race cars in where rims and tires take the impact,most importantly rear wheel contract.

I had another car hit me squarely on the right rear tire and rim to have my axle bust at the hub,and there goes the tire.

Alot of racers tend to pay attention to gears and their condition,and take the rest of the rear end for granted. Pay close attention to your rear end!

i like to pull axles every other race last week i changed gears (thanks Rico found 3.90 i wanted from SUMMIT) so i figured maybe i put something together wrong or had a c-clip fail as both axles looked very good when i put them back in, but the c clip is still holding whats left of the axle in the tube. the right one broke before i don't want to put in a ford i just bought the gear i wanted and boy was the car fast.

Ive broken 2 in one night like your first one,the part left on the wheel makes a nice spacer if you drill out the holes to 5/8. thats the most common, nothing you can do that will help in my opinion.

get a aftermarket rs axle.

Wouldn't it be the LEFT bearing that has little to no oil thru most of the race? Or are you turning right?

do they make an axle for a metric 7.5 in a Nova?

Glad you found the gear mike,8.5 rears are stronger in the gear area but seem to be weak in the axle department.I beleive this has alot to do with the distance from the axle bearing to hub,maybe a metric 7.5 is less distance 'cause i have not seen many of them break axles like the 8.5's.I think a s-10 7.5 may work under a camaro/nova.I'm with dirt the drivers side bearing is the one that will starve for grease,the passenger side will drown in grease.

i had the same problem and finally went to a buick/olds axle. they have a little more meat where the bearing rides at. after i switched i had no problems.
