What can fail
During intense acceleration, the ball joint connecting the lower control arm to the rear suspension knuckle can shift out of position. This increases stress on the knuckle, which may crack and cause the vehicle corner to drop and the control arm to contact the wheel.
What the fix does
Install a revised rear suspension knuckle assembly that securely retains the ball joint in position.
