Solution

1. Preparation

Gather tools including a jack, jack stands, tire pressure gauge, torque wrench, and wheel balancer.
Park the vehicle on a level surface and ensure the engine is off.

2. Tire Balancing

Sub-step 1: Remove the wheel from the vehicle using a jack and jack stands.
Sub-step 2: Mount the tire on a wheel balancer and spin to identify unbalanced areas.
Sub-step 3: Add balancing weights as needed and recheck for balance.
Sub-step 4: Reinstall the wheel to the vehicle, ensuring lug nuts are torqued to the manufacturer’s specifications (typically around 80-100 ft-lbs).

3. Tire Pressure Adjustment

Sub-step 1: Use a tire pressure gauge to check each tire's pressure.
Sub-step 2: Inflate or deflate tires to match the manufacturer's recommended PSI, usually found on the driver’s door jamb.

4. Suspension Inspection

Sub-step 1: Visually inspect all suspension components, looking for cracks, wear, or loose parts.
Sub-step 2: If damaged components are found, replace with OEM or high-quality aftermarket parts.

5. Wheel Alignment

Sub-step 1: Take the vehicle to a professional alignment shop.
Sub-step 2: Have a technician perform a four-wheel alignment to adjust angles to manufacturer specifications.

6. Driveshaft and Axle Inspection

Sub-step 1: Inspect the driveshaft for any signs of bending or damage.
Sub-step 2: Check axles for proper attachment and any visible wear; replace if necessary.
