  Q: How to remove and replace the rear Control Arm on BMW Z3?

  A: The independent rear suspension on E30 models consists of left and right trailing arms with pressed-in wheel bearings and bushings. To remove the trailing arm, the drive axle can be removed without special tools. However, if replacing the trailing arm, special tools are needed for the drive flange and wheel bearing. The process involves removing the wheel center caps, loosening the axle spindle nut, and removing the axle from the rear wheel hub. The parking brake cable and hydraulic brake line should be disconnected, and the lower shock bolt should be removed to lower the trailing arm. The through bolts and lock washers can then be removed to lower the trailing arm from the vehicle. When installing, the rear suspension fasteners should be torqued to the specified values. For E36 models, the independent rear suspension includes trailing arms, upper and lower control arms, and allows for easy adjustment of rear toe and camber. The process for removing and replacing the trailing arm is similar to that of E30 models, with the addition of removing the rear spring, disconnecting the upper sway bar bracket, and removing the ABS cable. The upper control arm and lower control arm can also be removed and replaced, with the process involving disconnecting the driveshaft from the differential and supporting the differential assembly. The specified torque values should be followed when installing the control arms.
