Common Issues with Corolla Steering Gear?
2 Answers
The common issue with the Corolla is abnormal noise from the steering wheel. The main reasons are as follows: 1. The steering column lacks lubrication, resulting in high friction, insufficient lubrication at the universal joint, or rust on the steering shaft. 2. Check if the power steering fluid is low or if there is abnormal noise from the steering gear's rack and pinion. 3. Inspect the steering knuckle for any issues and check if soundproofing cotton or debris is entangled under the steering gear. 4. The rubber bushings of the suspension stabilizer bar links may have aged and hardened. 5. The steering wheel's fixing screws may not be tightened properly, causing noise; if the steering wheel has been replaced, friction between plastic parts may produce noise.
As an automotive enthusiast, I've studied the Corolla's steering system and found that the common issues with the steering gear mainly include oil leaks and abnormal noises. In older hydraulic power steering models, the steering gear's seals are prone to aging and leaking, leading to reduced power assistance and heavy steering, making driving particularly strenuous. Abnormal noises often manifest as creaking sounds during turns, indicating internal bearing or gear wear. Although oil leaks are rare in newer electric power steering models, occasional control module failures can cause unresponsive or interrupted power assistance. Regular checks of steering fluid and unusual chassis noises are effective detection methods. Early detection and replacement of seals or bearings can save on major repair costs. Corollas with over ten years of mileage are more prone to these issues, and neglecting them can lead to greater hazards affecting handling safety.
