I put new GM bearings in about 5000 miles ago & already I feel a little play (12 & 6 test).



Is there a better quality bearing than oem or am I just going to have to change them once a year?



Running 2x a month autox plus practices on 710's.

Fronts or rears or both?

Mine lasted near 55,000 miles I got timken from autozone. GM makes some for racers only.

I just checked the fronts, with such low miles on them I was surprised to feel the movement. I am sure they are still within spec, but they are looser than when I put em on.

Front BJ's are new so the movement is def. in the bearing assm.

Do you have a part # for the race stuff? Get thru dealer or ?

John Shiels

I think you need to be a real race team like LGM and he replaces them every 3 races or something like that. Not sure on the difference. They may just pick the tighter ones? May be Dave Farmer knows more.

Thanks,

I know some guys get the "lifetime" bearings at an auto parts store, but some are junk & it's not worth the labor if you need to r&r every 3 or 4 months.

I use the '94 Firebird bearings on mine. If you don't have a drill press, just take the bearings to a machine shop and have the mounting holes drilled to allow the Corvette bolts to pass thru them.

Autozone sells them and they're made by Timken. $109 for the Firebird ones versus $189 for the Corvette version. Btw, the Timken ones use OEM style wheel studs with the unthreaded guide tips.

Why do you drill them? Just install the bolt from the other side and
thread it into the bearing.

On mine, the stock bolts wouldn't thread into the Firebird bearings (bolts were too thick).

Timken Bearings from AutoZone. Same bearing as GM uses but at 1/3 the price and in Timken box not a GM ( HIGH MAKR UP ) box
