  Q: How to service and repair the control arm bushing on Buick Park Avenue?

  A: Starting the Control Arm Bushing servicing and repair process requires first removing the Control Arm from the vehicle. The long bolt with thrust bearing (J21474-27) should be installed through bushing receiver (J41014-2) so it seals the Control Arm Bushing with a washer on top. Apply high pressure lubricant (J23444-A) to the bolt thread. Install the bushing remover (J41014-1) with its small end facing the bushing along with both the thrust bearing and long nut (J21474-4) onto the long bolt with thrust bearing (J21474-27). After driving the bushing out of the Control Arm with the correct tightening of the nut you can remove the bushing tools. To install the bushing start by inserting it into the Control Arm and position its flat section vertically and facing toward the rear. To install the long bolt with thrust bearing (J21474-27) place it through bushing remover (J41014-1) alongside the washer to compress the bushing while inside the Control Arm. Then add high pressure lubricant (J23444-A) to the bolt threads before fitting the bushing installer (J21474-13) with large end directed toward the bushing and attaching the thrust bearing and long nut (J21474-4). Finally, tighten the bolt to set the bushing in position. First tighten the bolt completely to push the bushing fully inside the Control Arm before removing the tools for bushing installation. The Control Arm can then be mounted to its frame position.
