from the tire completely and then remove the hub
nuts.

down the engine.

opposite the one you are going to repair. Put a jack
under the truck frame.

• Hub nut tightening torque: See page 4-4.
7. After installing the tire to the truck, adjust the
inflation pressure to the standard inflation pressure,
if needed.

tires, except that the position of the jack goes under the
counterweight.
