Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles before starting.

2. Inspect and Replace Suspension Components

Inspect the Struts/Shocks:
- Remove the wheel using a socket set.
- Check for leaks or damage on struts/shocks.
- If damaged, proceed to remove them.
Remove Struts/Shocks:
- Disconnect the top mounting bolts using a ratchet and appropriate socket.
- Remove the lower mounting bolts while supporting the strut with a jack.
- Take out the strut/shock assembly from the vehicle.
Install New Struts/Shocks:
- Position the new strut/shock into the mounting location.
- Torque the lower bolts to the manufacturer’s specifications (usually around 40-50 ft-lbs).
- Reinstall the top mounting bolts, ensuring they are torqued properly.

3. Check and Adjust Wheel Alignment

After replacing struts/shocks, take the vehicle to a professional alignment shop.
Ensure alignment specifications meet manufacturer’s recommendations.
