- Park the vehicle on a level surface and apply the parking brakes. Chock the tires.
- Check the U-bolt torque. See Table for U-bolt torque
specifications. Tighten in a diagonal pattern as shown in Fig. . Set a click-type
torque wrench to the mid-point torque value for the fastener being
checked. Turn the wrench in a clockwise motion (looking up) until
the torque wrench clicks, then release pressure on the torque wrench,
and turn the wrench again until it clicks. If the nut turns on the
second application, the bolt is stretching and must be replaced. See of the Cascadia™ Workshop Manual for
bolt replacement procedures.
