Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Inspection and Replacement

Sub-steps:
- Check tire pressure using a tire gauge; inflate to manufacturer specifications if low.
- Inspect for visible damage or bulges; replace any damaged tires.
- Rotate tires if uneven wear is detected.
Tools Required: Tire gauge, jack, jack stands, tire iron.

3. Suspension Component Inspection and Replacement

Sub-steps:
- Visually inspect shocks and struts for leaks or signs of wear.
- If worn, remove the old shocks/struts using a socket set and install new ones, ensuring proper torque specifications are followed (typically around 30-50 Nm for upper mounts).
- Check and replace any damaged bushings or control arms.
Tools Required: Socket set, torque wrench, pry bar.

4. Wheel Alignment Adjustment

Sub-steps:
- After replacing suspension components, take the vehicle to a professional alignment shop.
- Ensure that all angles (camber, caster, toe) are adjusted to manufacturer specifications.
Tools Required: Alignment machine (professional service).

5. Sway Bar Inspection and Replacement

Sub-steps:
- Inspect the sway bar links and bushings for wear or damage.
- If necessary, replace with new parts, ensuring to torque to manufacturer specifications (typically around 20-30 Nm).
