Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, engage the parking brake, and place wheel chocks behind the rear wheels.

2. Tire Inspection and Adjustment

Tools Required: Tire pressure gauge, air compressor, lug wrench
Check tire pressure using a tire pressure gauge and inflate to the recommended PSI if needed.
Inspect tires for any bulges, punctures, or uneven wear. Replace any damaged tires.

3. Wheel Balancing

Tools Required: Wheel balancer
Remove the front wheels using a lug wrench.
Mount the wheels on a wheel balancer and spin to check for imbalances.
Add wheel weights as necessary to achieve balance, following the manufacturer's specifications.

4. Wheel Alignment

Tools Required: Alignment machine
Reinstall balanced wheels on the vehicle.
Use an alignment machine to check and adjust the wheel alignment according to OEM specifications.
Adjust camber, caster, and toe settings as required.

5. Suspension Inspection and Replacement

Tools Required: Socket set, torque wrench, pry bar
Inspect suspension components visually for wear or damage.
If any parts are worn, replace them using a socket set and torque to manufacturer specifications.
- Example: Control arm bolts typically require 85 Nm (62 lb-ft) of torque.

6. Brake Inspection

Tools Required: Brake caliper tool, socket set
Remove the front wheels again and inspect brake rotors for warping using a run-out gauge.
Replace warped rotors and worn brake pads as necessary.
