Solution

1. Preparation

Tools Required: Jack, jack stands, wrench set, socket set, torque wrench, pry bar.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery before starting work on electrical components.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding to work underneath.

Sway Bar Links and Bushings:
1. Locate the sway bar links and bushings.
2. Use a wrench to remove the nuts securing the links.
3. Inspect for wear or damage; replace if necessary.
4. Install new sway bar links and torque to manufacturer specifications (usually around 30 Nm).
Strut Mounts:
1. Remove the wheel to access the strut assembly.
2. Use a socket set to remove nuts securing the strut mount.
3. Inspect the strut mount for cracks or separation.
4. Replace if damaged and torque the new mount to manufacturer's specifications.
Control Arms and Bushings:
1. Inspect control arms for any visible damage or excessive play.
2. Remove any loose components and use a pry bar to check bushings for wear.
3. Replace control arms or bushings as necessary and torque to specifications.

4. Reassemble and Lower the Vehicle

Reinstall the wheels and ensure all bolts are tightened to the specified torque.
Lower the vehicle carefully back to the ground.

5. Final Inspection

Double-check all suspension components for proper installation.
Ensure no tools or debris are left in the engine bay or under the vehicle.
