REMOVAL & INSTALLATION Control Arm Shaft
See Figures 1 and 2
- Remove the front coil spring as previously described.
- Count the shims at each end of the cross-shaft, then unbolt it from the frame and remove the control arm.
- Remove the bolts, washers, and collars from both ends of the shaft, then screw in a 7 / 16 in. X 20 capscrew into one end of the shaft.
- Support the control arm in a press and press on the capscrew until the bushing is forced from the arm.
- Unscrew the capscrew and repeat the procedure on the other end on the cross-shaft.
- Position the replacement cross-shaft and/or bushings in the control arm and start the bushings into the arm.
- Place the assembly in a press, put a spacer over the bushing, and press into place.
- Repeat the procedure for the other end, then install the collar and lockwasher but loosely thread in the bolts.
- Reverse the removal procedure to install the spring and lower control arm. After the arm is installed, lower the vehicle to the floor and tighten the cross-shaft bushing bolts to 45-55 ft. lbs.
- The procedure for replacing the upper control arm shaft is the same as for the lower control arm shaft, except a 3 / 8 in. X 24 capscrew is used to remove the bushings. Torque the bushing bolts to 35-40 ft. lbs.
The upper and lower control arms are removed by combining the operations for replacing the upper and lower cross-shafts and the operations for replacing the steering knuckle.
