Rear Wheel & Axle Housing Alignment

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 1985 GMC Vandura Special, 1985 GMC Vandura, 1985 GMC Rally Camper Special, 1985 GMC Rally, and 1985 GMC Magnavan. However, it is still accessible from the selected car via links, so may be relevant.
  1. If rear tire wear indicates that axle housing may be bent, check alignment. Back vehicle squarely onto alignment machine. Compensate for wheel runout in same manner as when for checking front wheel toe-in.
    NOTE: Due to the fact the vehicle is backed onto alignment machine, the actual toe-out will be read on the scale as toe-in. If tram (scuff) gauge is used to check toe-out, disregard this note.
  2. Check camber. Camber reading should be 3° negative to 5° positive. Check toe-in. Proper toe-in is 0° to .05° (0" to 1/16"). If vehicle is not within specification, check and straighten frame and/or related components as necessary.
NOTE: Equipment used to straighten frame must allow rechecking of camber and toe-in without removing axle housing from vehicle.
