I have a 1982 TA and the wheel bearings listed are to small for the knuckle. Do not have the original wheel bearings or rotors. The driver side knuckle says GM4 and 1197N; the passenger side says GM6 and 1198N. Measured the upper shaft with a crescent wrench and t was 1 1/4 inch.


What type of spindle/knuckles do I have and what are the inner and outer bearings to use?

 

You have 3rd gen Camaro/Firebird spindles.

Correct bearing part #s are Set 6 & Set 34. A6 & A34 in some brands.

You'll need the grease seal too; part # is 8871.
