Our flange holding tool locks the differentials input flange in place. It prevents the shaft from turning while you loosen or torque the high-torque pinion nut (often over 250 lb-ft) during seal replacements or gear setups. The tool bolts directly to three of the driveshaft bolt holes on the pinion yoke.

Leverage Point: Features a 1/2" square drive for a breaker bar to brace against the vehicle, frame, or ground.
Preload Control: Holds the flange still so you can accurately crush a crush sleeve or set bearing rotational preload
