Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery if working on electronic components.

2. Raise and Support Vehicle

Use a jack to lift the vehicle and place jack stands under the frame for safety.
Remove the wheels for better access to suspension components.

3. Inspect and Replace Components

Shock Absorbers/Struts:
- Remove the upper mounting bolts and lower bolts from the shock/strut assembly.
- Replace with new, OEM-spec components.
Sway Bar Links:
- Unbolt the sway bar link from the sway bar and control arm.
- Install new sway bar links and torque to specifications (usually around 30 Nm).
Bushings:
- Remove any components necessary to access the bushings (like control arms).
- Press out old bushings and press in new ones, ensuring they are seated properly.

4. Reassemble and Torque

Reinstall all suspension components in reverse order.
Use a torque wrench to tighten all bolts to manufacturer specifications (refer to service manual for specific torque values).
Reattach the wheels and lower the vehicle back to the ground.
