Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Inspect and Replace Worn Suspension Components

Remove Wheel:
- Use a jack to lift the vehicle and secure it on jack stands.
- Remove the wheel lug nuts with a socket set and take off the wheel.
Inspect Suspension:
- Examine the control arms, bushings, shocks/struts, and sway bar links for any visible damage or wear.
- Use a pry bar to check for movement in the bushings or ball joints.
Replace Worn Parts:
- If any components are damaged or excessively worn, replace them with new parts.
- For the control arms, remove the bolts using a socket set and replace them with new control arms.
- Replace bushings by pressing out the old ones and inserting new ones.
- For shocks/struts, unbolt them from the top and bottom mounts, and replace with new units.

3. Reassemble and Lower Vehicle

Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower Vehicle:
- Remove the jack stands and lower the vehicle back onto the ground.
- Torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).
Reconnect Battery:
- Reconnect the battery terminal.
