Disconnect the battery to prevent electrical issues during repairs.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Remove the front wheels to access suspension components.
3. Visually inspect control arms, bushings, and struts for cracks or excessive play.
4. If damaged, remove the affected components using a socket set and replace them with new ones.
5. Torque new components to manufacturer's specifications.

3. Check and Tighten Drivetrain Components

Sub-steps:
1. Inspect the driveshaft and differential for any signs of wear or loose bolts.
