Rear Wheel & Axle Housing Alignment

  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.
