Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely lift it using a hydraulic jack and jack stands.
Disconnect the negative terminal of the battery to avoid any electrical issues.

2. Inspect and Replace Suspension Components

Inspect Upper and Lower Control Arms
- Remove the wheel using a socket set.
- Check control arms for cracks, bends, or worn bushings.
- If damaged, unbolt the control arm and replace it with a new one. Torque to manufacturer specifications.
Check Struts/Shocks
- Visually inspect for leaks and physical damage.
- If replacement is needed, unbolt the strut assembly from the top mount and lower control arm.
- Install new struts and torque bolts to specification.
Replace Worn Bushings
- Remove any components obstructing access to bushings (e.g., sway bar).
- Use a bushing press to remove old bushings and install new ones.
- Ensure proper alignment during installation.

3. Reassemble and Reinstall

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications.
Reconnect the negative battery terminal.
