Warning Signs of a Failing Front Lower Control Arm:
- Clunking or rattling noises from the front suspension, especially over bumps.
- Loose or wandering steering. The car may feel unstable.
- Uneven tire wear. One tire may wear down faster than the other.
- Vibration in the steering wheel.
- Poor alignment. The car may pull to one side.
How to Test if the Control Arm is the Problem:
- Visual Inspection: Look for cracks, bends, or damage to the control arm itself. Check the bushings (rubber parts) for wear, cracks, or tears.
- Movement Test: With the car safely supported, try to move the wheel by hand. Excessive play or movement indicates a problem with the control arm or its bushings.
- Pry Bar Test: Use a pry bar to carefully check for movement in the bushings. Excessive movement means they are worn.
- Listen Carefully: Have someone turn the steering wheel while you listen for noises coming from the control arm area.
Common Failure Causes:
- Normal wear and tear over time.
- Impacts from potholes or accidents.
- Corrosion from road salt and moisture.
- Worn or damaged bushings.
