How to DIY and Replace W164 Front Suspension Lower Control Arm

Replacing W164 front suspension lower control arm can be a DIY-friendly task. Follow this simple step-by-step guide to get it done. Before starting, ensure to have the right tools and safety precautions in place. Here’s how to replace W164 front suspension lower control control arms:

• Preparation:

  Park the vehicle on a level surface, engage the parking brake, and wear safety gear. Gather the necessary tools, including jacks, jack stands, lug wrench, sockets, ratchet, torque wrench, and alignment tools. Disconnect the vehicle's battery to prevent any electrical issues. Take note of the vehicle's audio codes, if applicable.

• Lift the Vehicle:

  Use the lug wrench to loosen the wheel nuts slightly while the vehicle is on the ground. Then, utilize the jack to lift the vehicle and place it on the jack stands. Remove the wheels to access the lower control arms easily.

• Remove the Stabilizer Bar Links:

  Locate the stabilizer bar links connected to the lower control arm. Use appropriate socket and wrench sizes to remove the bolts securing the links. Move the stabilizer bar links aside without damaging the attached components.

• Disconnect the Ball Joints:

  Identify the ball joints connecting the lower control arm to the steering knuckle. Depending on the vehicle's design, use a ball joint separator tool or a hammer to disconnect the ball joints from the steering knuckle. Be cautious not to damage the boot or surrounding components.

• Detach the Lower Control Arm Bushings:

  Locate the lower control arm bushings connecting the arm to the vehicle's frame. Use appropriate socket and ratchet to remove the bolts securing the bushings. Depending on the design, a bushing removal tool or a press may be required to detach the bushings from the control arm.

• Remove and Replace the Lower Control Arm:

  Use a socket and ratchet to remove the bolts securing the lower control arm to the vehicle's chassis. Carefully lower the jack or support holding the control arm and remove it from the vehicle. Install the new control arm by reversing the removal steps. Ensure all bushings and joints are adequately lubricated, if necessary, before installation.

• Reconnect the Ball Joints and Stabilizer Bar Links:

  Reconnect the ball joints to the steering knuckle and secure them using the manufacturer's specified torque. Reattach the stabilizer bar links to the control arm and tighten the bolts securely.

• Reassemble and Lower the Vehicle:

  Reattach the wheels and lower the vehicle off the jack stands. Tighten the wheel nuts securely and follow the manufacturer's recommended torque specifications. Once the vehicle is on the ground, tighten the wheel nuts using a torque wrench to ensure even tightening.

• Reconnect the Battery:

  Reinstall the battery and connect the terminals in the correct order (negative to positive). Start the vehicle and ensure all systems function properly. If the control arm bushings were replaced, allow a short break for the bushings to settle before performing an alignment.

• Check Wheel Alignment:

  After replacing the control arm, it's essential to get a professional wheel alignment. This ensures proper handling, tire wear, and vehicle stability. Follow the alignment technician's recommendations for post-alignment procedures.
