1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Adjust Tires

Sub-steps:
1. Check tire pressures and inflate to manufacturer specifications if needed.
2. Inspect tire tread for uneven wear or damage and replace if necessary.
3. Perform a wheel alignment if any misalignment is detected.
Tools Required: Tire pressure gauge, floor jack, jack stands, tire iron.

3. Examine Suspension Components

Sub-steps:
1. Visually inspect control arms, bushings, and struts for wear or damage.
2. Use a pry bar to check for play in the bushings and joints.
3. Replace any worn or damaged components with OEM parts.
Tools Required: Pry bar, socket set, torque wrench.

4. Driveshaft and Axle Inspection
