Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Lift the vehicle using a jack and secure it with jack stands.

2. Inspect Suspension Components

Sub-steps:
- Remove the wheel on the affected side using a socket set.
- Visually inspect the strut, coil spring, and control arms for cracks or breaks.
- Check the sway bar links and bushings for deterioration.
Tools Required: Socket set, jack stands, wheel chocks.

3. Replace Worn Components

Sub-steps:
- If any components are found worn or damaged (e.g., sway bar links, bushings, or struts), replace them.
- For sway bar links, use a wrench to disconnect the old links and install new ones, ensuring they are properly torqued according to specifications (typically around 40 Nm).
- For struts, remove the top mount and lower bolts, replace the strut, and secure all hardware.
Tools Required: Torque wrench, socket set, strut spring compressor (if replacing struts).

4. Reassemble and Test

Sub-steps:
- Reinstall the wheel and tighten the lug nuts to the manufacturer's specifications (typically 120 Nm).
- Lower the vehicle and perform a bounce test to verify repairs.
- Check alignment if necessary, as replacement of suspension components can affect it.
Tools Required: Torque wrench, alignment tools (if needed).
