  1. 1

    Drive over minor speed bumps to isolate whether the noise comes from the front left or front right side.

    Spray a specialized penetrating lubricant fluid directly into the rubber control arm ball joint boot to see if the squeak stops temporarily.

  3. 3

    Securely hoist the car on jack stands and remove the front wheels to inspect the suspension links.

  4. 4

    Unbolt the upper control arm pinch bolt from the steering knuckle assembly.

  5. 5

    Remove the inner mounting alignment bolts that lock the upper control arm into the unibody frame.

  6. 6

    Install a redesigned sealed heavy-duty front upper control arm assembly with upgraded weather boot seals.
