Suspension U-Bolt Torque Check

rv mm 32.06.000

Check the U-bolt torque of both the front and rear axles where applicable.

Notice: Failure to retorque the U-bolt nuts could result in spring breakage and abnormal tire wear.

  1. Park the vehicle on a flat surface, apply the parking brake, and chock the tires.
  2. Check the U-bolt torque in a diagonal pattern. See Fig.. Set a click-type torque wrench to the highest torque value for the fastener being checked. See Table. for U-bolt torque specifications. Turn the wrench in a clockwise motion (looking up) until the torque wrench clicks.
  3. Remove the chocks.
