If your lower control arm is failing, you may experience one or more of the following symptoms:

  • Clunking or Knocking Noises: Metallic sounds from the front suspension when driving over bumps or turning
  • Uneven or Rapid Tire Wear: Premature or irregular tire wear patterns due to compromised alignment
  • Vibration Through Steering Wheel: Noticeable vibrations felt in the steering wheel, floorboard, or seats while driving
  • Vehicle Pulls to One Side: The Coaster drifts left or right while driving on a straight road
  • Loose or Unstable Steering: Wandering feeling and difficulty maintaining a straight line
