my Toyota Corolla E140 (2006-2013) steering wheel shakes at high speeds what's causing it

Solution

1. Tire Inspection and Replacement

• Sub-steps:
  1. Remove the wheel covers if equipped.
  2. Inspect each tire for damage; replace any tires that are worn or damaged.
  3. Check tread depth and ensure it meets legal limits; replace if necessary.

2. Wheel Balancing

• Sub-steps:
  1. Remove the wheels from the vehicle using a socket set.
  2. Mount each wheel on a wheel balancer.
  3. Add weights as required to balance the wheels, following the balancer's recommendations.
  4. Reinstall the wheels and torque the lug nuts to factory specifications (typically 76-83 ft-lbs for Corolla).

3. Alignment Adjustment

• Sub-steps:
  1. Set the vehicle on an alignment rack.
  2. Measure the alignment angles (caster, camber, toe).
  3. Adjust the tie rods to bring the toe settings within manufacturer specifications.
  4. Recheck all angles after adjustments and ensure they fall within the specified limits.
