ADJUSTMENT

Fig. 1: Checking bearing axial play

Fig. 2: Checking the bearing for smoothness of rotation

Fig. 3: Checking rotational force using a spring scale

Fig. 4: Adjusting rotational force — tighten or loosen the hub nut until a reading of 1.3–2.4 lbs. is attained

  1. Raise and support the front end on jackstands. Check both the bearing axial play and the ease and smoothness of rotation. Axial play should be 0; the wheel should rotate smoothly, with no perceptible bearing noise.
  2. Remove the wheel. Remove the brake drum or disc brake caliper. Suspend the caliper out of the way. Don't disconnect the brake line.
  3. Attach a spring scale to a wheel lug.
  4. Pull the scale horizontally and check the force needed to start the wheel turning. The force should be 1.3–2.4 lbs. If the reading is not correct, proceed.
  5. Remove the grease cap and cotter pin.
  6. Tighten or loosen the hub nut until the correct pull rating is obtained.
  7. Align the cotter pin holes and insert a new cotter pin. Replace the grease cap and wheel.
