Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, inspection mirror.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with jack stands before working underneath.

2. Replace Worn Components

Identify Worn Parts: From the visual inspection, determine which parts (shocks, struts, bushings) need replacement.
Remove Wheel:
- Loosen lug nuts with a socket set.
- Jack the vehicle and secure it with jack stands.
- Remove the wheel to access suspension components.
Remove Old Component:
- For shocks/struts: Remove the retaining bolts and disconnect any attached components (e.g., sway bar links).
- For bushings: Use a pry bar to remove worn bushings from control arms or subframes.
Install New Component:
- Position the new shock or strut and secure it with the retaining bolts, tightening to manufacturer specifications.
- For bushings, press in the new bushings and ensure they are seated properly.
Reassemble:
- Reattach any removed components (e.g., sway bar links).
- Reinstall the wheel and tighten the lug nuts to the specified torque.
Lower Vehicle: Carefully remove jack stands and lower the vehicle to the ground.
