5. Our original track bar wasn't showing signs of wear, but considering its age, and since we were under the truck anyway, we decided to install a new Skyjacker adjustable track bar. The install began with the new track-bar mount. It uses four mounting points. The bolt shown installs after an existing hole in the rear of the crossmember is drilled all the way through. The other bolt on the driver side (hidden behind the installer's hand) utilizes an existing hole.
