  Q: How to service and repair the idler arm on Mercury Grand Marquis?

  A:

  Starting the idler arm service and repair process requires securely raising the vehicle. Start the procedure by removing both the nut and the cotter pin then the nut and washer. Professional service starts with disconnecting the steering sector shaft arm drag link followed by eliminating the steering idler arm with its bracket through bolting, washer, and nut removal. When performing installation work make sure to position the idler arm straight ahead toward the vehicle centerline before installing all components including the bracket and steering idler arm with their respective bolts, washers and nuts. Position the steering sector shaft arm drag link onto the steering idler arm and bracket while you add the washer and new cotter pin and the nut. Finally, lower the vehicle.
