Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

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

3. Inspect and Replace Worn Components

Shocks/Struts:
- Remove the top mounting bolts using a socket set.
- Disconnect the bottom bolt from the knuckle.
- Remove the old shock/strut assembly.
- Install the new shock/strut assembly in reverse order, tightening to manufacturer specifications (typically around 25-30 ft-lbs for top bolts and 90-110 ft-lbs for bottom bolts).
Sway Bar Links:
- Remove the sway bar link bolts using a wrench.
- Inspect the bushings for wear.
- Replace with new sway bar links, ensuring proper torque (around 30-40 ft-lbs).

4. Reassemble and Lower Vehicle

Reinstall any components that were removed for access.
Lower the vehicle from the jack stands carefully.
Tighten all lug nuts to manufacturer specifications (typically around 76 ft-lbs).
