  2. Loosen rear bolt on retaining plate. Set Wrench (5038) on rear bolt and turn suspension assembly so hole in retaining plate passes hole in suspension tower at least .12" (3 mm). See Fig. 1. Mark position when hole can no longer be seen and turn wrench an additional

    .12" (3 mm).

  3. Mark position of new hole with a punch. Tighten rear nut to 35 ft. lbs. (48 N.m) so strut will not move out of position.


  4. Drill a new hole in retaining plate, through hole in top of suspension tower. Use care not to damage hole in suspension tower. Install and tighten front press bolt and nut. Tighten bolt in retaining plate. Remove front press bolt and replace with new bolt, nut and lock washer. Tighten bolt to 35 ft. lbs. (48 N.m).


CASTER ADJUSTMENT


Caster angle can be adjusted by replacing the control arm strut. A shorter strut reduces caster angle by .8 degrees. A longer strut increases caster angle by .8 degree.
