Solution

1. Preparation

Gather Tools: OBD-II scanner, socket set, torque wrench, jack stands, wheel chocks.
Safety Precautions: Ensure the vehicle is on a flat surface and use wheel chocks. Disconnect the battery if working on electrical components.

2. Replace Worn Bushings

Remove Wheel: Loosen lug nuts, lift the vehicle with a jack, secure with jack stands, and remove the wheel.
Access Control Arm: Remove the bolts securing the control arm using a socket set.
Replace Bushings: Remove the old bushings with a bushing tool and install new ones, ensuring they are seated correctly.
Reinstall Control Arm: Torque the bolts to the manufacturer specifications.

3. Replace Shock Absorbers

Remove Old Shocks: Loosen and remove the bolts securing the shock absorber at both ends.
Install New Shocks: Position the new shock absorber and torque bolts to manufacturer specifications.
Reinstall Wheel: Place the wheel back on, hand-tighten the lug nuts, and lower the vehicle to the ground.

4. Wheel Alignment

Perform Alignment: After replacing suspension components, take the vehicle to a professional for a wheel alignment to ensure proper handling.
