REMOVAL & INSTALLATION
- Raise the vehicle, support it with jackstands, and remove the wheel and tire assembly.
- Remove the brake caliper as previously outlined.
- Remove the dust cap and remove the wheel bearing nut after removing the cotter pin.
- Remove the wheel bearing, hub, and disc assembly from the spindle.
Install the disc, bearing, washer and nut. Adjust the wheel bearing as follows:
- Spin the wheel forward by hand. Torque the nut to 12 ft. lbs. (16 Nm)to fully seat the bearings.
- Back off the nut 1 / 4 - 1 / 2 turn until it is just loose, the tighten the nut finger-tight.
- Loosen the nut until either hole in the spindle lines up with a slot in the nut and then insert the cotter pin. This may appear to be too loose, but it is the correct adjustment.
- Proper adjustment creates a 0.001-0.005 in. (0.025-0.127mm) of end-play.
- Install the wheel and tire assembly, remove the jackstands and lower the vehicle.
See Figure 1
- Check the disc for any obvious defects such as excessive rust, chipping, or deep scoring. Light scoring is normal on disc brakes.
- Make sure there is no wheel bearing play and then check the disc for runout as follows:
- Install a dial indicator on the caliper so that its feeler will contact the disc about one inch below its outer edge.
- Turn the disc and observe the runout reading. If the reading exceeds 0.002 in. (0.05mm) the disc should be replaced.
All brake rotors (discs) have a minimum thickness dimension cast into them, on the hub between the lugs. This is the minimum wear dimension and not a refinish dimension. Do not reuse a brake rotor that will not meet specifications. Replace with a new rotor.
Refinishing of brake rotors can be handled at machine shops equipped for brake work.
