This procedure covers removal and replacement of the rear wheel bearing hub assembly on a 1966 Chevrolet Corvette with independent rear suspension, including axle spindle service and proper torque specifications.
Warnings
⚠The 1966 Corvette uses a unique independent rear suspension with cambered half-shafts. Improper bearing adjustment can cause differential failure or wheel detachment.
⚠Never support the vehicle by the rear differential carrier alone. Use jack stands under the frame or rear trailing arms.
⚠️The rear coil springs remain under tension during this procedure. Do not disassemble suspension components beyond what is specified in this procedure.
ℹ️The rear wheel bearings on the 1966 Corvette are tapered roller bearings that require manual packing and proper preload adjustment, not sealed hub assemblies.

Preparation
- Park vehicle on level surface and engage parking brake firmly.
- Loosen rear wheel lug nuts while vehicle is on the ground.
- Raise rear of vehicle and support securely on jack stands under the frame rails, not the differential.
- Remove rear wheel and tire assembly.
- Place drain pan under work area to catch any residual gear oil from the differential or axle.
Procedure
- 1Remove brake caliper assemblyRemove the two caliper bracket bolts securing the rear brake caliper to the spindle support. Use a breaker bar if necessary as these bolts are torqued to specification. Carefully lift the caliper and bracket assembly off the rotor and suspend it from the suspension using a caliper hanger or mechanic's wire. Do not allow the caliper to hang by the brake hose.Torque specBrake Caliper Bracket Bolts110 Nm (81 lb-ft)
- 2Remove brake rotor and dust capPull the brake rotor straight off the spindle. If stuck due to corrosion, thread two bolts into the threaded holes in the rotor face and tighten evenly to press the rotor off. Once removed, pry off the grease dust cap from the center of the spindle using a flat blade screwdriver or pry bar. Work carefully around the circumference to avoid distorting the cap.
- 3Remove cotter pin and spindle nutStraighten and remove the cotter pin from the castellated spindle nut using cotter pin pliers or side cutters. Discard the old cotter pin. Using a large socket or spindle nut wrench, remove the spindle nut from the axle shaft. Keep track of the nut and any washers behind it.
- 4Remove outer bearing and spindleRefer to the factory service manual: the rear spindle and bearings are housed in a bearing support carrier bolted to the trailing arm, and the spindle is press-fit. Remove the bearing support assembly from the trailing arm and use a press to separate the spindle from the support and bearings; do not attempt to pull these components off by hand. shaft.
- 5Remove inner bearing and seal from spindleWith the spindle removed, turn it over and pry out the inner grease seal from the back side using a seal puller or flat blade screwdriver. Discard the seal. Remove the inner bearing cone from the spindle bore. Inspect both bearing cones for pitting, scoring, or discoloration indicating overheating.
- 6Remove old bearing racesUsing a brass drift punch and hammer, drive out the inner and outer bearing races from the spindle bore. Work around the circumference of each race, alternating sides to drive it out evenly. Clean the bearing bores thoroughly with parts cleaner and a wire brush. Inspect the bores for any damage, cracks, or excessive wear.
- 7Install new bearing racesPlace the new outer bearing race into the front of the spindle bore and drive it in squarely using a bearing race driver or large socket that contacts only the outer edge of the race. Tap evenly around the circumference until the race is fully seated against the shoulder in the bore. Repeat this process for the inner bearing race, installing it from the rear of the spindle. Verify both races are fully seated and not cocked in the bore.
- 8Pack bearings with greaseUsing a bearing packer tool or by hand, pack both the inner and outer bearing cones completely with high-temperature wheel bearing grease. If packing by hand, place a glob of grease in your palm and press the bearing into it, forcing grease up through the rollers from the wide end until grease emerges from the narrow end. Continue until all rollers are completely surrounded by grease. Coat the bearing races in the spindle with a thin layer of grease as well.
- 9Install inner bearing and sealPlace the packed inner bearing cone into the inner race in the spindle. Apply a thin coat of grease to the outer lip of the new inner seal. Using a seal driver or large socket, carefully drive the new seal into the rear of the spindle until it is flush with or slightly below the spindle face. Ensure the seal goes in straight and is not cocked. Apply a light coat of grease to the sealing lip.
- 10Install spindle assembly onto axleCarefully slide the spindle assembly onto the axle shaft, guiding it over the shaft and aligning it with the differential output flange. Push it on until the inner bearing is fully seated on the axle shaft. Ensure the spindle slides on smoothly without binding.
- 11Install outer bearing and adjust preloadPlace the packed outer bearing cone onto the axle shaft and into the outer race. Install the washer and thread the spindle nut onto the axle shaft by hand. Rotate the spindle assembly while tightening the nut to seat the bearings. Install and torque the spindle flange nut to the factory specification. Bearing preload on this IRS spindle is set by a collapsible spacer or selective shim, NOT by backing off the nut to create endplay. Verify rolling torque/preload against factory service manual specification; do not attempt to set endplay by loosening the nut. Install a new cotter pin where applicable, bending the ends to secure. Install a new cotter pin through the castellated nut and axle shaft, bending the ends to secure.Torque specAxle Nut200 Nm (148 lb-ft)
- 12Install dust capPack the cavity behind the outer bearing with additional wheel bearing grease, filling it about two-thirds full. Do not overfill as this can cause seal failure. Tap the grease dust cap back into place using a soft-faced mallet, striking evenly around the outer edge until it is fully seated.
- 13Reinstall brake rotor and caliperSlide the brake rotor onto the spindle, ensuring it seats fully against the hub face. Remove the caliper from its hanger and position it over the rotor. Install the caliper bracket bolts and torque them to specification. Ensure the brake pads are properly positioned on either side of the rotor.Torque specBrake Caliper Bracket Bolts110 Nm (81 lb-ft)
- 14Final bearing check and wheel installationGrasp the spindle at the 12 o'clock and 6 o'clock positions and attempt to rock it. There should be minimal play (0.001-0.005 inches). Spin the assembly by hand to verify smooth rotation with no grinding or binding. Install the wheel and tire assembly, threading lug nuts by hand first. Lower vehicle until tire just contacts ground, then torque lug nuts to factory specification in a star pattern.
Reassembly
- After initial test drive, re-check wheel bearing adjustment and verify no unusual noise or vibration from the rear suspension.
- Inspect for any grease leakage around the dust cap or inner seal after 50-100 miles of driving.
- The independent rear suspension geometry means bearing adjustment directly affects camber and toe; consider alignment check if vehicle pulls or tire wear is uneven.
Verification
- Spin each rear wheel by hand with vehicle raised. Rotation should be smooth with slight bearing drag, no grinding or roughness.
- Check for any lateral play by grasping the tire at 3 o'clock and 9 o'clock positions and attempting to rock it. Minimal movement (0.001-0.005 inches) is acceptable, excessive play indicates loose bearing preload.
- Test drive vehicle at various speeds and listen for humming, grinding, or rumbling from rear wheel bearings. Noise that changes with vehicle speed indicates bearing issues.
- Verify brake function is normal with firm pedal and no pulsation during moderate braking.
- Check that grease dust cap is secure and no grease is being thrown onto wheel or brake components.
