I. Is it necessary to replace the steering gear if it makes abnormal noise?
Steering gear noise doesn’t necessarily require replacement; it depends on the specific situation. Generally, if the steering gear makes a persistent, unabated noise or affects driving safety, then replacement may be necessary. However, if it’s just an occasional, slight noise, immediate replacement may not be necessary. You can first check the steering gear’s lubrication or other components for problems. It’s best to have a professional automotive mechanic inspect and diagnose the issue.
II. What are the causes of abnormal steering gear noise?
Steering gear noise may be caused by the following reasons:
- Wear and tear on internal steering gear parts, such as gears and bearings.
Insufficient or poor lubrication of the steering gear, leading to dry friction of internal parts and abnormal noise.
Loose steering gear housing or loose steering gear mounting bolts, causing abnormal noise during operation.
Dust or debris entering the steering gear, causing abnormal operation and abnormal noise.
Loose connections between the steering gear and the vehicle, such as a loose connection between the steering gear and the steering wheel, can also cause abnormal noise from the steering gear.
III. How to Solve Steering Gear Noise
When abnormal noise occurs in the steering gear while driving, it may be due to various reasons. Here are some methods to solve the problem:
1. Check the hydraulic fluid level
Both low and high hydraulic fluid levels can cause abnormal noise from the steering gear. Therefore, before ruling out other problems, first check if the hydraulic fluid level is correct. If the fluid level is too low, add the appropriate amount of hydraulic fluid; if the fluid level is too high, drain the excess fluid.
2. Check if the lines are installed correctly
Abnormal noise from the steering gear can also be caused by incorrect line connections. Therefore, check if the hydraulic lines are installed correctly, ensuring that the line connections are tight and reliable, without any looseness or leaks.
3. Check if any connecting parts are loose
Loose connecting parts can also cause abnormal noise from the steering gear. Therefore, it is necessary to check all connecting parts, including bolts, nuts, pins, etc., to ensure they are all securely tightened and not loose.
4. Check if all safety valves are functioning properly.
A malfunctioning safety valve can also cause abnormal noises from the steering gear. Therefore, it is necessary to check if all safety valves are functioning properly, ensuring they can open and close correctly and are not blocked or leaking.
5. Check if the oil filter, control valves, unloading valves, directional valves, and various valves in the hydraulic system are loose or blocked.
Loose or blocked components in these parts can cause abnormal noises from the steering gear, so it is necessary to check if they are securely tightened and not blocked.
6. Check the steering gear lubricating oil.
Insufficient or poor-quality steering gear lubricating oil can also cause abnormal noises from the steering gear, so it is necessary to check if the steering gear lubricating oil is sufficient and if it needs to be replaced.
7. Check if the flanges and bolts at the steering gear connections are loose.
Loose flanges and bolts at the steering gear connections can also cause abnormal noises from the steering gear, so it is necessary to check if they are securely tightened and not loose.
8. Check if the mechanical driveshaft is installed correctly.
Incorrect installation of the mechanical driveshaft can also cause abnormal noise from the steering gear. Therefore, it is necessary to check if the mechanical driveshaft is installed correctly and ensure that its connection with the steering gear is secure.
IV. Can I drive if there is abnormal noise from the steering gear?
You can drive if there is abnormal noise from the steering gear, but it is not recommended, as it may be dangerous. The steering gear is the most important component for steering in a car and is also an important guarantee for driving safety. If there is abnormal noise from the steering gear, it will affect driving safety. The cause should be found out as soon as possible, and repairs or replacements should be made if necessary. When driving in the future, pay attention to the following points:
Avoid turning the steering wheel while stationary; try to turn the steering wheel only after the vehicle has started moving.
When the vehicle has come to a complete stop, the steering wheel should be returned to the center position to avoid load on the suspension system and tires.
When turning, try to avoid turning the steering wheel to the lock position.
