Idler Arm: Testing and Inspection
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 and support it with jackstands. Refer to Vehicle Lifting.
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.
2. Position the wheels straight-ahead and install anti-rotation pin J 42640.
3. Install runout gauge J 45101 between the idler arm and the vehicle frame.
Ensure the runout gage is at zero before taking the measurement.
4. Place scale J 35999 near the relay rod end of the idler arm.
