Q: How to service and repair the pitman arm on Cadillac Catera?
A: The procedure for servicing or fixing the Pitman Arm starts with properly supporting and raising the vehicle. Use the relay rod removal tool (J42400) to release the relay from the Pitman Arm while you have already taken off the relay rod to Pitman Arm ball stud nut. Safer methods than driving wedges should be used to disconnect steering linkage joints because this practice provides risk of both seal damage and early equipment failure. After matching the Pitman Arm layout with the steering gear splines, remove the Pitman Arm nut and washer with attention to the rubber steering gear shaft protector. The tool j6627-a serves to remove the Pitman Arm through the tie rod / wheel stud remover function. Start by positioning the front wheels at straight ahead while also placing the rubber steering gear shaft protector. Position the Pitman Arm shaft against the marked scribe of the steering gear while installing it for assembly. Both the Pitman Arm and steering gear include blind splines as their design. Use a new Pitman Arm washer followed by tightening the nut to 160 nm (118 ft. Lbs.). The relay rod needs to be put back onto the Pitman Arm while using the linkage installer (J42089) for the ball stud of the relay rod. Secure the new self-locking Pitman Arm ball stud nut by applying 30 nm (22 ft. Lbs) torque. Apply the linkage installer (J42089) to the relay rod ball stud once you remove it before fastening the relay rod to the Pitman Arm ball stud nut at 60 nm (44 ft. Lbs.). Adjust the toe until the steering wheel reaches its proper specification after lowering the vehicle.
