Suspension TufTrac Gen2 I-Bolt Torque Check

49X mm 32.03.001

Notice: Failure to retighten the I-Bolts could result in spring breakage and abnormal tire wear.

Check the I-Bolt torque of both the front and rear axles and suspension spring packs where applicable.

  1. Park the vehicle on a level surface, shut down the engine and set the parking brake. Chock the tires.
  2. Check the I-Bolt torque. See Table. for I-Bolt torque specifications. Tighten in a diagonal pattern as shown in Fig. and 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.
