Front Wheel Bearings

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1990 GMC Suburban, 1990 GMC Pickup, 1990 GMC Cab & Chassis, 1990 Chevrolet Suburban, and 1990 Chevrolet Pickup. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Never preload tapered roller bearings or damage to bearings will result. Bearings are designed to have a slightly loose feel when properly adjusted.
  1. Raise and support vehicle. Remove hub dust cap and cotter pin. Tighten spindle bearing nut to 12 ft. lbs. (16 N.m) while turning wheel forward by hand. Back off nut until it is just loose.
  2. Finger tighten nut until snug. Loosen nut slightly until new cotter pin can be installed (not more than 1/2 flat). Hub play (in and out) should be .001-.005" (.03-.13 mm) when properly adjusted. Install dust cap and wheel cover.
