REPAIR PROCEDURE: 1. Raise the vehicle on an alignment rack (drive-on lift). 2. Verify the road tires are correctly sized and the tire tread is not excessively worn. Replace any worn tire before proceeding. Any new or old replacement tire should be equal to the original tires that came with the vehicle when it was new. Tire wear is not covered by the vehicle warranty. 3. Set the tire pressure for the FRONT TIRES to the following specification, regardless of the load being carried by the vehicle . Tire Size FRONT Tire Pressure LT235/80R17EorLT245/70R17E 448 Kpa (65 psi) LT265/70R17EorLT285/70R17E 414 Kpa (60 psi) 4. Set the tire pressure for the REAR TIRES as recommended for the vehicle configuration and load that is being carried at the time. Tire Size REAR Tire Pressure LT235/80R17EorLT245/70R17E Refer to the Tire Inflation Chart brochure in the Owners Manual or to the placards located either on the face of the driver’sdoor or on the driver’sside”B”pillar.

Verify that the steering damper is operating correctly. a. Unbolt the end of the damper at the axle end. b. Cycle the damper rod by hand. c.

Attempt to rotate the dustcover by hand. b. If the dustcover on an outer tie rod end can be rotated, or is free and loose, then replace the tie rod (regardless of joint wear). 7. Inspect each outer tie rod end for internal wear. a. Maximum allowed wear (joint travel) fora tie rod end is 1.15 mm (0.045 in.). b. Install a dial indicator to the tie rod end (in-line with the vertical stud of the tie rod end). c. With a pry bar placed between the steering linkage and the axle tube, pry upwards while measuring the amount of joint travel (wear). d. Measure the amount of wear in the other outer tie rod end joint. e. If wear (joint travel) in either outer tie rod end is greater than 1.15 mm (0.045 in.), then replace the worn tie rod end. 8. Verify the torque on each outer tie rod end stud nut. The nut should be tightened to 122 Nm (90 ft. lbs.). 9. Make sure any worn outer tie rod ends have been replaced before proceeding further. 10. Verify all other steering linkage connections are tightened to their torque specifications.
