Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Safety warning: Always wear safety goggles and gloves when working on the vehicle.

2. Tire Inspection and Replacement (if necessary)

Sub-steps:
1. Remove wheel covers or hubcaps (if applicable).
2. Use a tire pressure gauge to check and adjust tire pressures to manufacturer specifications.
3. Inspect tire tread depth and replace if worn beyond safe limits.
Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.

3. Shock Absorber/Strut Replacement

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Unbolt the shock absorber/strut from the top mount (inside the engine bay) and lower control arm.
4. Install the new shock absorber/strut, ensuring it is properly aligned and bolted down to manufacturer torque specifications.
5. Reinstall the wheel and lower the vehicle back to the ground.
Tools Required: Socket set, torque wrench, spring compressor (if dealing with struts).

4. Replace Sway Bar Links/Bushings (if necessary)

Sub-steps:
1. Inspect sway bar links and bushings for wear.
2. Unbolt and remove the damaged sway bar links.
3. Replace with new sway bar links/bushings, ensuring they are tight.
Tools Required: Wrench set, socket set.

5. Wheel Alignment

Sub-steps:
