Overview
The rear wheel bearing assembly on 1963–1982 Corvettes is a critical component of the trailing arm. Unlike modern "hub units," these require precise shimming to achieve the correct end play. Proper setup when rebuilding bearing assemblies prevents spindle failure and "rear-end steer" during cornering.
Frequently Asked Questions:
What are the signs of failing rear wheel bearings on a C2 or C3 Corvette?
The most common symptoms of rear bearing failure include:
-
Metallic chirping or growling: Noise that changes frequency with vehicle speed.
-
"Rear-end Steer": The car feels like it is wandering or "self-steering" under acceleration or braking.
-
Excessive Play: If you can rock the rear tire at the 3 and 9 o'clock positions while the car is jacked up, the bearings likely have excessive end play. 3 & 9 play is the 1st way to check bearing play. 12 and 6 o'clock will always have in and out play from the differential (GM allows for up to .125"), it's just the nature of the Corvette IRS due to posi clutch wear and the softer material used on side yoke axles.
-
Brake Pedal Pulsation: Worn bearings cause the rotor to wobble, pushing the brake pistons back into the calipers (pad-knock or knock-back).
What is the correct rear wheel bearing end play for a 1963-1982 Corvette?
Van Steel recommends a professional specification of .001" to .002" of end play. While the original GM factory manual allowed for .002 to .008" due to GMs manufacturing process, while modern standards have found a tighter tolerance ensures longevity and brake consistency.
Can I rebuild Corvette rear bearings without a press?
No. Rebuilding these assemblies requires a 20-ton shop press to remove and install the inner and outer bearing races and the spindle itself. Additionally, a specialized Setup Tool is required to measure the shim thickness before final assembly. Just removing the spindle with a hammer can damage the spindle much. Installing it without a press, like with a hammer, can damage the spindles and/or the bearings.
What parts are included in a Van Steel Rear Bearing Rebuild Service?
Our professional rebuild service includes:
-
New Timken Bearings and Races: The industry standard for durability.
-
New Inner and Outer SKF Seals: High-temperature resistant seals.
-
Precision Shimming: Custom-fit to your specific bearing support.
-
New French Locks and Grade 8 Hardware: Ensuring the half shaft and spindle remain secure.
-
Racing-Grade Grease: To prevent moisture intrusion and heat breakdown.
- Rotor Run out: All of our kits that include a rotor have a rotor run out performed and the spindle and rotor get marked so they are always installed in the correct orientation. If you order an assembly without rotors, you MUST perform a rotor run out for optimal braking performance (.005 MAX rotor run out).
