1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection and Replacement

Steps:
- Remove the wheel covers or hubcaps if applicable.
- Use a jack to lift the vehicle and secure it with jack stands.
- Inspect tires for uneven wear or damage.
- Check tire pressure and adjust to the manufacturer’s specifications.
- If tires are damaged or significantly worn, replace them with new tires of the same specifications.
Tools Required: Jack, jack stands, tire pressure gauge, tire iron.

3. Suspension Component Inspection and Replacement

Steps:
- Visually inspect control arms, bushings, and strut assemblies for wear or damage.
- Replace any worn or damaged suspension components. Use a torque wrench to tighten bolts to manufacturer specifications.
Tools Required: Socket set, torque wrench, pry bar.

4. Driveshaft and Axle Inspection
