Solution

1. Preparation

Park the vehicle on a flat surface and engage the parking brake.
Gather all necessary tools and parts.
Wear safety gloves and goggles for protection.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Suspension Components

Inspect Components: Check control arms, struts, and shocks for damage.
Replace Shocks/Struts: If shocks or struts are worn:
- Remove the wheel to access the suspension.
- Unbolt the top and bottom mounts of the strut/shock using a socket set.
- Remove the strut/shock from the vehicle.
- Install the new strut/shock in reverse order, ensuring all bolts are torqued to manufacturer specifications (typically around 50-80 ft-lbs).

4. Replace Bushings and Mounts

Inspect Bushings: If bushings are cracked or worn:
- Remove the affected control arm or mount.
- Use a bushing removal tool to press out the old bushing.
- Press in the new bushing using the same tool.
- Reinstall the control arm or mount, ensuring proper torque settings.

5. Reassemble

Reinstall the wheel and lower the vehicle.
Torque the wheel lug nuts to manufacturer specifications (typically around 80-100 ft-lbs).
