Control Arm Bushing


Removing Control Arm Bushings

  • Raise the vehicle and support the frame on safety jack stands.
  • Remove the wheel assembly.
  • Install a spring compressor on the coil spring.
  • Disconnect the ball joint studs from the steering knuckle.
  • Remove the bolts attaching the control arm assembly to the frame and remove the control arm.
    • Old bushings are pressed or driven out of the control arm. It is important that the control arm holes not be damaged by the process.
  • A c-clamp tool can be used to press out the bushing.
  • The C-clamp is installed over the bushing.
  • An adapter is selected to fit on the bushing and push the bushing through the control arm.
  • Turning the handle on the C-clamp pushes the bushing out of the control arm.
  • An air chisel can be used to drive out the bushing.

If an air chisel is used, be sure that the chisel bit is wide and dull. If it is sharp, it will cut the bushing rather than push it out.

Installing Control Arm Bushings

New bushings can be installed by driving or pressing. When installing new bushings, make sure they are driven in straight. A poor installation could enlarge the hole in the control arm.

  • Adapters are available for the C-clamp tool to install the new bushings.
  • After the correct adapters are selected, position the bushing and tool on the control arm as shown below.

  • Turning the C-clamp handle pushes the bushing into the control arm.
  • Once the new bushings are started into the control arm, measure and mark the center between mounting holes and center the control arm.
  • Now, alternately press in the bushings on each side, keeping the reference marks aligned. This ensures the shaft is not off center, causing binding.
  • End cap nuts or bolts should not be torqued until the vehicle is at curb height and the suspension has been bounced and allowed to settle out.
  • Rebolt the control arm and tighten the bolts to specifications, then install the coil spring into position.
  • Install the ball joint studs into the control arms.
  • Remove the coil spring compressor. Install the wheel assembly and lower the car.
  • Road test the car, retighten all bolts, and set wheel alignment.
Some older vehicles use a bushing that is all metal instead of a metal-rubber combination. These are removed and replaced in the same way as the rubber and metal type just described.
