Pre-Alignment Checks

NOTE: Before making wheel alignment adjustments, perform the following checks.
  1. Wheel bearings must be properly adjusted.
  2. Steering linkage and suspension must not have excessive looseness. Check for wear in tie rod ends and ball joints.
  3. Tires should be approximately equal in tread wear and runout must not be excessive. Tires and wheels should be in balance, and inflated to manufacturer's specifications.
  4. Vehicle must be at curb height with full fuel load, no passenger load, spare tire in place but no extra load in vehicle.
  5. Vehicle must be on level floor with suspension settled. Bounce front and rear of vehicle several times and allow it to settle to normal running height.
  6. If steering wheel is not centered with front wheels in straight ahead position, correct by shortening one tie rod adjusting sleeve and lengthening opposite sleeve equal amounts.
  7. Ensure wheel lug nuts are tightened to manufacturer's specifications.
