GM 90510647
Center Link

To service and fix the Center Link, start by raising and supporting the vehicle while ensuring supplementary support is added at the other end, so that it cannot drop from the hoist. Pull off the inner trace rod ball studs nuts, and use the tie rod / wheel stud puller (J6627-A) to transfer the internal trace rods from the relay rod. Then, pull out the relay rod ball stud nut from the Pitman Arm and use the relay rod removal tool (J42400) to lift the relay rod ball stud from the Pitman Arm. Repeat the same process for the Idler Arm. For installation, connect the relay rod to the Idler Arm using linkage installer (J42089) on the relay rod ball stud by tightening it to 30 nm (22 ft. Lbs.) to make sure that the ball stud taper sits well. Use washers and nuts to mount the linkage damper (J42089) that came from the disassembled clutch linkage. Fine-tune the adjustment until the clutch clutch pedals are aligned. Reinstall the cylinder hat, the clutch pressure plate, and clutch release arm. Install the relay rod to the Pitman Arm and remove the linkage installer (J42089) and tighten to 30 nm (22 ft. Lbs.), reinstall and remove. Replace with anewlabel self-locking relay rod ball stud nut and tighten it to 60 nm (44 ft. Lbs.). Insert the inner tie rods into the relay rod, using the linkage installer (J42089) apply on the tie rod ball stud until it's tightened to 30 nm (22 ft. Lbs.) before removal. Finally, replace a new self-locking tie rod ball stud nut and tighten it to 60 nm (44 ft. Lbs.) lowered the vehicle and toe adjust to the correct specification.
