Solution

1. Preparation

Gather necessary tools and parts.
Raise the vehicle on a jack and secure it with jack stands.
Remove the wheel to access the suspension components.

2. Inspect and Replace Worn Components

Shock Absorbers
- Remove the upper and lower mounting bolts using a socket set.
- Pull the shock absorber out of its mounting location.
- Install the new shock absorber by reversing the removal process. Torque the bolts to manufacturer specifications (typically around 40 Nm).
Control Arm Bushings
- Remove the control arm by loosening the bolts connecting it to the chassis and the lower ball joint.
- Use a press to remove the old bushings and install new ones.
- Reinstall the control arm, ensuring bolts are torqued to specification (usually around 60 Nm).
Sway Bar Links
- Disconnect the sway bar links from the sway bar and control arm by removing the nuts.
- Install new sway bar links and torque the nuts to the specified value (generally around 30 Nm).

3. Reassemble

Reattach the wheel and lower the vehicle.
Ensure all components are tightened to specified torque values.
