why does my Honda Civic shake when I drive over 60 mph

Solution

1. Preparation

• Gather tools: jack, jack stands, tire pressure gauge, impact wrench, torque wrench, wheel balancing machine.
• Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Adjust Tire Pressure

• Sub-steps:
  1. Remove valve caps from all tires.
  2. Use the tire pressure gauge to measure the pressure in each tire.
  3. Inflate or deflate tires to the manufacturer's recommended pressure (found in the owner’s manual or on the driver's side door jamb).
  4. Reinstall valve caps.

3. Check and Balance Wheels

• Sub-steps:
  1. Remove the wheels using an impact wrench.
  2. Take the wheels to a wheel balancing machine.
  3. Adjust weights on the rim as required to achieve balance.
  4. Reinstall wheels, tightening lug nuts to the specified torque (usually 80-100 ft-lbs).

4. Inspect Suspension and Steering Components

• Sub-steps:
  1. Lift the vehicle with a jack and secure it on jack stands.
  2. Visually inspect all suspension components (control arms, bushings, ball joints) for signs of wear or damage.
  3. Replace any worn or damaged components as needed.

5. Perform Wheel Alignment

• Sub-steps:
  1. Take the vehicle to a professional alignment shop or use an alignment tool if available.
  2. Adjust camber, caster, and toe settings to factory specifications.
  3. Test drive the vehicle to confirm alignment is correct.
