32–03 Suspension U-Bolt
Torque Check
CAUTION
Failure to retorque the U-bolt nuts could result in
spring breakage and abnormal tire wear.
1. Park the vehicle on a flat surface and apply the
parking brakes. Chock the tires to prevent the
vehicle from moving.
2. Check the U-bolt high nut torque in a diagonal
pattern. Set a click-type torque wrench to the
highest torque value for the fastener being
checked. See
Table 1 for U-bolt torque specifica-
tions. Turn the wrench in a clockwise motion
(looking up) until the torque wrench clicks.
Remove the chocks.
