Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues during repairs.

2. Lift the Vehicle

Use a floor jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands to ensure stability.

3. Inspect and Replace Components

A. Suspension Components

Inspect the shock absorbers and struts:
- If leaking or damaged, remove the old shock or strut.
- Install new shock absorbers or struts, tightening bolts to manufacturer's specifications (usually around 40-50 Nm).
Check sway bar links:
- If any link is worn or damaged, remove it using a socket set.
- Install new sway bar links, ensuring they are torqued properly.

B. Tighten Loose Bolts

Inspect all suspension mounting points and bolts.
Tighten any loose bolts to the specified torque values.

4. Reassemble and Lower the Vehicle

Reattach any components that were removed for inspection.
Remove jack stands and lower the vehicle back to the ground.
