Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.

Control Arm Bushings:
- Remove the control arm bolts using a socket set.
- Replace any worn bushings with new ones, ensuring they are properly seated.
Strut Assembly:
- Remove the strut assembly by unbolting it from the knuckle and strut tower.
- Inspect for leaks and replace if necessary.
Sway Bar Links:
- Unbolt the sway bar links using a wrench.
- Install new sway bar links, ensuring they are tightened to manufacturer specifications (typically 30-40 Nm).

4. Reassemble and Lower the Vehicle

Reattach the wheel and lug nuts, ensuring they are tightened to manufacturer specifications (typically 100-120 Nm).
Lower the vehicle back to the ground.
