    2. Warning: Be sure that the fasteners are torqued correctly. Fasteners that are not tight can cause separation of components or premature failure of components, loss of vehicle control and possible personal injury or property damage.

  2. Check that the torque on the number one spring bracket lock bolts is 45 to 63 lbf·ft (62 to 85 N·m). See Fig..
  3. Inspect the leaf springs for worn or broken spring leaves.
  4. Inspect the cam surfaces of the number two spring bracket and number three spring bracket for wear due to high mileage. See Fig.. Also check the inner side edges of the hanger legs for wear. Excessive wear on the sides of the legs is an indicator there my be problems with the spring eye bushing. Excessive wear at either point requires that the spring hanger be replaced.
