Solution

1. Preparation

Gather necessary tools.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and the keys are removed from the ignition.

2. Tire Inspection and Inflation

Tools Required: Tire pressure gauge, air compressor
Check tire pressure with the gauge and inflate tires to the recommended PSI.
Look for any visible signs of tire damage such as cuts or bubbles.

3. Wheel Balancing

Tools Required: Wheel balancer
Remove the wheels from the vehicle using a socket set.
Mount each wheel on the wheel balancer and spin to identify any imbalance.
Add wheel weights as necessary to achieve balance, then reattach wheels.

4. Wheel Alignment

Tools Required: Alignment machine
Follow the manufacturer’s specifications for alignment adjustments.
Adjust camber, caster, and toe angles as needed to ensure proper alignment.

5. Suspension Inspection

Tools Required: Jack and jack stands, socket set
Raise the vehicle and support it securely with jack stands.
Inspect struts, shocks, and bushings for signs of wear or damage.
Replace or repair any worn components as necessary.

6. Driveshaft and CV Joint Check

Tools Required: Inspection tools (flashlight, pry bar)
Inspect the driveshaft for any signs of damage or imbalance.
Check CV joints for wear or torn boots and replace if necessary.
