Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Lift the front of the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Worn Components

Sway Bar Links and Bushings
- Remove the sway bar link bolts using a socket set.
- Replace any worn sway bar links and bushings with new ones.
- Torque the bolts to the manufacturer's specifications (typically around 15-20 ft-lbs).
Struts and Shocks
- Remove the strut assembly by taking off the top strut mount nuts inside the engine bay and the bolts at the bottom of the strut.
- Inspect struts for leaks; if damaged, replace with new struts.
- Reassemble by following the installation steps in reverse, ensuring all bolts are torqued to specification.

3. Reassemble and Lower Vehicle

Reinstall any components that were removed for inspection or replacement.
Ensure all bolts and nuts are tightened to the specified torque values.
Lower the vehicle back to the ground and remove jack stands.
