Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, lubricant
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery (if required) for safety.

2. Inspect and Replace Suspension Components

Raise the Vehicle:
- Use the jack to lift the vehicle and secure it on jack stands.
Check and Replace Bushings:
- Identify worn bushings in the control arms and sway bar.
- Remove the bolts using the socket set.
- Use a pry bar to remove the old bushings and install new ones, ensuring proper alignment.
- Torque the bolts to manufacturer specifications (check the service manual for exact values).
Examine Sway Bar Links:
- Inspect the sway bar links for wear.
- Remove any damaged links with the socket set and replace them with new ones.
Inspect Shocks/Struts:
- If struts/shocks are leaking or not functioning properly, remove them by unbolting from the top and bottom mounts.
- Install new shocks/struts according to manufacturer instructions, ensuring they are torqued correctly.

3. Lubricate Components

Apply a suitable lubricant to any moving parts, including bushings and joints, to reduce friction and noise.

4. Reassemble and Lower Vehicle

Reinstall any components removed during inspection and ensure all hardware is tightened to specifications.
Carefully lower the vehicle from the jack stands.
