I am overhauling my suspension this winter/spring and will be replacing my wheel bearings with Timkens in the process. My problem is I'm not sure which bearings I need as my camaro is an RS but has the F41 suspension package. Am I correct that the F41 is the Z28 suspension and I need the bearings for the Z28 as the outter bearings are different than the RS?

RS outters are set34. Z28 outters are set3. Inners are set6 for both.

Please set me straight so I can get the right bearings!

 

All standard brakes have the A6 inner and A34 outer. The 1LE is a bit different.

so the A3(National/federal mogul #) is for the 1LE? I wish the parts stores could tell me that.

 

Yes. The A3 outer bearing, which the 1LE uses, has a larger OD than the standard A34 bearing.
