Torque Check
NOTICE
Failure to retorque the U-bolt nuts could result in
spring breakage and abnormal tire wear.
Check the U-bolt torque of both the front and rear
axles where applicable.
1. Park the vehicle on a level surface, shut down
the motor and set the parking brake. Chock the
tires.
2. Check the U-bolt torque. See Table 2 for U-bolt
torque specifications. Tighten in a diagonal
pattern as shown in
Fig. 3 . 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
