1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools and parts.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Balance

Sub-steps:
1. Remove all four wheels from the vehicle using a socket set.
2. Inspect the tread depth and sidewalls for damage.
3. Balance the tires using a tire balancing machine.
4. Reinstall wheels and torque to the manufacturer’s specifications (typically 100 lb-ft for most Mustangs).

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Adjust the toe, camber, and caster settings per the manufacturer's specifications.
3. Test drive to ensure proper alignment and handling.

4. Driveshaft Inspection

Sub-steps:
1. Raise the vehicle on jack stands for access to the driveshaft.
2. Inspect for signs of wear, cracks, or imbalances.
3. If damaged, replace the driveshaft with a new unit.
4. Ensure all connections are torqued to specifications.

5. Suspension Component Inspection

Sub-steps:
1. Visually inspect shocks, struts, and bushings for signs of wear.
2. Replace any worn components with OEM or high-quality aftermarket parts.
3. Reassemble and ensure all nuts and bolts are tightened to specifications.

6. Wheel Bearing Check

Sub-steps:
1. Lift the vehicle and remove the wheel.
2. Spin the hub and listen for any grinding noise.
3. If there is play, replace the wheel bearing assembly.
4. Grease the new bearing and install it according to the manufacturer’s torque specifications.
