Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Safety warning: Use jack stands when lifting the vehicle.

2. Tire Inspection and Adjustment

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Inspect each tire for bulges, cracks, or uneven tread wear.
3. Inflate tires to the manufacturer’s recommended pressure.
4. Replace any damaged tires as needed.

3. Wheel Balancing

Sub-steps:
1. Remove the wheel and tire assembly from the vehicle.
2. Mount the wheel on a wheel balancer.
3. Add or adjust wheel weights according to the balancer's reading.
4. Reinstall the wheel on the vehicle, ensuring proper torque (typically 80-100 ft-lbs for G70).

4. Alignment Adjustment

Sub-steps:
1. Drive the vehicle to a professional alignment shop or use a DIY alignment tool.
2. Adjust camber, caster, and toe settings to meet manufacturer specifications.
3. Test drive to confirm alignment adjustments have resolved any pulling.

5. Suspension Component Repair or Replacement

Sub-steps:
1. Inspect each suspension component visually for wear.
2. Replace any worn bushings, shocks, or struts with OEM or high-quality aftermarket parts.
3. Reassemble the suspension and ensure all bolts are torqued to manufacturer specifications.
