Caster Adjustment (Pickup)

  1. Check tire inflation. Place front wheel on turning radius gauge and level vehicle (unladed). On 2WD models, remove hub cap and cotter pin. On 4WD models, remove free wheeling hub assembly.
  2. On all models, measure caster with camber/caster/kingpin gauge attached. See WHEEL ALIGNMENT SPECIFICATIONS  table. If caster is not within specification, remove shock absorber mounting nut and lock nut.
  3. Compress shock absorber and loosen upper arm mounting bolts and nuts. Adjust caster by increasing or decreasing shims between upper arm shaft and crossmember. See Figure .
CAUTION: Difference in shim thickness between front and rear must be .16" (4 mm) or less. DO NOT use more than 3 shims at one location.
