Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety gear such as gloves and safety glasses.

2. Tire Balance and Alignment

Tools Required: Wheel balancer, alignment machine, torque wrench.
Remove the wheels from the vehicle.
Mount the wheels on a wheel balancer and spin them to check for balance. Add weights as needed to achieve balance.
Reinstall the wheels and perform a four-wheel alignment using an alignment machine according to manufacturer specifications.

3. Tire Inspection and Replacement

Inspect tires for any visible damage or uneven wear patterns.
If tires are worn or damaged:
- Tools Required: Tire changer, tire pressure gauge.
- Remove the old tires from the rims and install new tires.
- Inflate new tires to the manufacturer-recommended pressure.

4. Suspension Component Inspection

Tools Required: Jack, jack stands, socket set.
Lift the vehicle using a jack and secure it on jack stands.
Inspect the suspension components for signs of wear or damage (bushings, control arms, struts).
Replace any worn or damaged suspension components with OEM parts.

5. Verify Lug Nut Torque

After reinstalling wheels, use a torque wrench to ensure all lug nuts are torqued to factory specifications (typically around 80-100 ft-lbs depending on the model).

6. Driveshaft and Axle Check (if applicable)

Inspect the driveshaft for any visible damage or signs of misalignment.
Check axle joints for play or wear.
Replace any damaged driveshaft or axle components as necessary.
