Replacing worn control arm bushings on a Subaru Outback is an essential maintenance task that helps restore proper suspension function and improves vehicle handling. Over time, these bushings can deteriorate due to age, exposure to the elements, or heavy driving conditions. This guide provides step-by-step instructions to help you safely replace them and extend the life of your vehicle.
Tools and Materials Needed
- Jack and jack stands
- Socket set and ratchet
- Breaker bar
- Ball joint separator
- Hammer
- Control arm bushing removal and installation tools (press or bushing removal tool)
- Replacement control arm bushings
- Lubricant or penetrating oil
- Safety gloves and goggles
Preparing the Vehicle
Start by parking your Subaru Outback on a flat surface. Engage the parking brake and wear safety gear. Use a jack to lift the vehicle and secure it with jack stands. Remove the wheel corresponding to the control arm you are replacing bushings on. This provides clear access to the suspension components.
Removing the Control Arm
Locate the control arm connected to the wheel hub and chassis. Using the appropriate socket, remove the bolts securing the control arm. Carefully detach the control arm from the vehicle, noting the orientation for reinstallation. If necessary, use a ball joint separator to disconnect the ball joint from the steering knuckle.
Removing the Worn Bushings
Secure the control arm in a vise or suitable work surface. Use a bushing removal tool or press to extract the worn bushings. Apply penetrating oil to ease removal if the bushings are stubborn. Clean the control arm thoroughly before installing new bushings.
Installing New Bushings
Align the new bushings with the control arm. Use a press or bushing installation tool to insert them properly. Ensure they are seated fully and correctly to prevent premature wear. Lubricate the bushings if recommended by the manufacturer.
Reinstalling the Control Arm
Reattach the control arm to the vehicle, tightening all bolts to the manufacturer’s specified torque. Reconnect the ball joint if disconnected. Double-check all fasteners and ensure everything is secure before lowering the vehicle.
Final Checks and Test Drive
Lower the vehicle and remove the jack stands. Reinstall the wheel and tighten the lug nuts. Start the vehicle and perform a test drive to check for proper handling and noise. If everything feels normal, your control arm bushings are successfully replaced, improving your Outback’s suspension performance.
