With the car jacked up in the air, it is a good time to check looseness in the front end due to bad kingpins or worn or loose wheel bearings. This is done my grabbing the wheel, top and bottom, and pushing and pulling on the top and bottom.

John Tedesco is shown rocking the wheel while while Clyde and Fred watch for "play" in the kingpins and wheel bearings. In the photo below, Fred and Randy work on tightening the wheel bearings that were found to be too loose.
