1. Park the vehicle on a level surface and apply the
parking brakes. Chock the tires.
2. Check the U-bolt torque. See
Table 6 for U-bolt
torque specifications. Tighten in a diagonal pat-
tern as shown in
Fig. 3. Set a click-type torque
wrench to the mid-point torque value for the fas-
tener being checked. Turn the wrench in a clock-
wise 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
Group 32 of the Cascadia
