Wheel Bearing: RX7

  1. Raise and support vehicle. Remove wheel assembly. Remove and wire aside brake caliper. Install a dial indicator against hub and measure axial movement. Axial movement should be zero. If specification is exceeded, adjust preload or replace wheel bearing.
  2. To adjust preload, remove grease cap, cotter pin and set cover. Loosen lock nut. Tighten to 14-22 ft. lbs. (20-29 N.m). Turn wheel hub a few times to seat bearings. Loosen lock nut slightly until it can be turned by hand.
  3. Attach spring scale to hub bolt, and measure preload. Note value. Tighten lock nut until preload is .09-2.2 lbs. (.4-1.0 kg) more than amount measured in step 2).
