Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is cool and wear safety gloves and goggles.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle as needed.
Secure the vehicle on jack stands to ensure stability while working.

3. Inspect and Replace Suspension Components

Inspect Shocks/Struts:
- Remove the wheel to access the strut/shock assembly.
- Check for oil leaks or physical damage to the shock/strut.
- If damaged, replace with new components, ensuring they match OEM specifications.
Check Control Arms and Bushings:
- Inspect control arms for cracks or play in the bushings.
- Replace any worn bushings or control arms, using a socket set to remove and install new parts.
Tighten or Replace Mounting Hardware:
- Inspect all bolts and nuts associated with suspension components.
- Tighten to the manufacturer’s torque specifications or replace any stripped or damaged hardware.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and lower the vehicle from the jack stands using the hydraulic jack.
Ensure everything is secure and properly torqued.
