Ball bearings in a socket joint enable the front wheels of your SUV to pivot when you turn the wheel. If you notice stiff spots as you steer through curves, your ball joints may be to blame. Other signs that it's time to replace worn ball joints for Mercury Mountaineer include early wear on tires or clunking sounds from the front of the vehicle. If you plan to install your Mountaineer ball joint replacement in your home garage, ask about the Loan-a-Tool Program.
