Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Torque wrench
- Tire pressure gauge
- Wheel balancer
- Basic hand tools (socket set, wrenches)
Safety Warnings:
- Ensure the vehicle is on a level surface and securely supported by jack stands.
- Wear safety glasses and gloves.

2. Tire Inspection and Adjustment

Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure in each tire.
- Inflate tires to the recommended specifications found on the door jamb sticker.
Inspect Tires:
- Look for any bulges, cuts, or foreign objects embedded in the tires.
- Note any uneven wear patterns that could indicate alignment or suspension issues.

3. Wheel Balancing

Remove Wheels:
- Loosen the lug nuts slightly, raise the vehicle with a jack, and remove the wheels.
Balance the Wheels:
- Mount each wheel on a wheel balancer.
- Follow the balancer's instructions to add weights as needed to achieve balance.

4. Suspension Inspection

Visual Inspection:
- Check suspension components such as control arms, bushings, and struts for cracks or excessive wear.
Test for Play:
- With the vehicle lifted, manually check for play in the suspension joints and wheel bearings.

5. Reassemble and Torque

Reinstall Wheels:
- Place the wheels back on the hubs.
- Hand-tighten the lug nuts.
Torque Lug Nuts:
- Use a torque wrench to tighten lug nuts to the manufacturer's specified torque (usually between 80-100 ft-lbs for most vehicles).
