This video shows me using Harbor Freight Item 99849 to remove a Ball Joint (with it’s Control Arm Assembly) from a 2009 Nissan Cube. During the 11th minute of the video, I switched from relying on only vibration to assist in the removal, to relying on both, vibration and a chisel (used as a wedge) to assist in freeing the ball joint from its housing. Ordinarily, the ball joint is secured by a pinch bolt which pinches two tabs of the steering knuckle, together. So, with the pinch bolt removed, the technique of driving a wedge between the two tabs proved helpful in freeing the ball joint. Still, the wedge, by itself, WITHOUT Harbor Freight’s Item 99849 3/4″ Forged Ball Joint Separator, wasn’t sufficient to remove the car’s other ball joint. So, If you’re planning on doing this project, I highly recommend having BOTH such a ball joint separator, and a variety of hammer-able chisels, handy. And, I neglected to wear, or to even mention eye-protection; I should have been wearing eye-protection during this project.
