Abstract
A tool is provided for adjusting the bearing pre-load and backlash of a differential. The tool has a U-shaped positioning member with an adjustable width base. Bi-directional ratchet heads are provided on the ends of the U, with tools thereon for engaging the side quills of the differential. Setting the ratchets to operate in opposite directions allows easy adjustment of the relative distance between the side quills, and consequently adjustment of the pre-load on the bearings for the differential. Setting the ratchets to operate in the same direction maintains a constant distance between the side quills, but shifts them back and forth in the differential housing, allowing easy adjustment of the backlash between the differential ring gear and the drive shaft pinion gear.
