Damage or distortion to a control arm bushing can result in changes in wheel alignment settings.

Visually inspect each rubber bushing for:

  • Signs of distortion,
  • Movement,
  • Off-center condition, and
  • Presence of heavy cracking.

Check metal bushings for:

  • Noise, and
  • Loose seals.

Sometimes bushings are in a position where visual inspection is difficult. Using a flashlight and mirror will sometimes help.

  • Push on the fenders of the vehicle while listening for noise.
  • To inspect bushings for looseness, use a prybar to see if the control arm can be moved.
