Solution

1. Preparation

Gather tools and parts needed for the repair.
Safely lift the vehicle using a jack and support it with jack stands.
Ensure the working area is clean and organized.

2. Inspect and Replace Worn Components

Inspect Struts and Shocks:
- Remove the wheel to gain access to the strut assembly.
- Check for any signs of oil leakage; if present, replace the strut.
Replace Sway Bar Links:
- Remove any fasteners securing the sway bar link.
- Disconnect the sway bar link from the sway bar and control arm.
- Install the new sway bar link and tighten to manufacturer specifications (typically around 40 Nm).
Examine Control Arms and Bushings:
- Inspect control arm bushings for cracking or wear.
- If worn, remove the control arm by unbolting it from the subframe and the steering knuckle.
- Replace the bushings as necessary and reinstall the control arm, ensuring proper torque (usually 60-80 Nm).

3. Reassemble and Lower Vehicle

Reattach the wheel and tighten the lug nuts in a star pattern to the specified torque (typically around 120 Nm).
Lower the vehicle from the jack stands and recheck all fasteners for tightness.
