Solution

1. Preparation

Gather necessary tools and parts for repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Components

Shocks/Struts Replacement
1. Lift the vehicle and secure it on jack stands.
2. Remove the wheel for better access to the suspension components.
3. Unbolt the top and bottom of the shock/strut assembly using the appropriate socket size (typically 13mm-18mm).
4. Remove the assembly and inspect for leaks or damage.
5. Install new shocks/struts, ensuring that all bolts are torqued to manufacturer specifications (check service manual for specific torque values).
Bushing Replacement
1. Inspect control arm and sway bar bushings for wear.
2. Remove the control arm or sway bar if necessary.
3. Use a bushing removal tool to extract the old bushings.
4. Press in new bushings, ensuring they are seated correctly.

3. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery.
Conduct a test drive to check for noise reduction and overall handling improvement.
