my Toyota Corolla E170 (2013-2019) vibrates at high speeds, how to fix it

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is off.
• Safety warning: Disconnect the battery before working on any electrical components.

2. Tire Inspection and Replacement

• Sub-steps:
  1. Remove the wheel covers or hubcaps (if equipped).
  2. Loosen the lug nuts slightly using a socket wrench.
  3. Lift the vehicle with a hydraulic jack and secure it with jack stands.
  4. Fully remove the lug nuts and take off the wheels.
  5. Inspect each tire for uneven wear and damage—replace any tires showing excessive wear.

Tools Required:

• Socket set
• Hydraulic jack
• Jack stands

3. Wheel Balancing

• Sub-steps:
  1. Mount the tire on a wheel balancer.
  2. Spin the tire to find any imbalance.
  3. Add wheel weights as necessary to balance the tire.
  4. Reinstall the balanced tires onto the vehicle and tighten lug nuts to the manufacturer’s torque specifications (typically around 76 ft-lbs for Corolla).

Tools Required:

• Wheel balancer
• Torque wrench

4. Suspension and Alignment Check

• Sub-steps:
  1. With the vehicle still lifted, visually inspect the suspension components like shocks, struts, and control arms for any damage or excessive wear.
  2. If any components are damaged, replace them as needed.
  3. Lower the vehicle and perform a wheel alignment using an alignment machine to ensure all wheels are properly aligned.

Tools Required:

• Alignment machine
• Basic hand tools for replacing suspension components
