Idler Arm Inspection
^
Tools Required
-
J 35999 Spring Scale
-
J 42640 Steering Column Anti-Rotation Pin
-
J 45101 Hub and Wheel Runout Gage
1. Raise the vehicle on a hoist. Support the vehicle with jackstands. Refer to Lifting and Jacking the Vehicle.
2. Position the wheels in a straight-ahead position and install the J 42640.
Notice: The wheels of the vehicle must be straight ahead and the steering column in the LOCK position before disconnecting the steering column
or intermediate shaft from the steering gear. Failure to do so will cause the SIR coil assembly to become uncentered, which may cause damage to
the coil assembly.
3. Install the dial indicator J 45101 between the idler arm and vehicle frame. Ensure the gage is at zero before taking a measurement.
4. Place a J 35999 near the relay rod end of the idler arm.
