Why Is My Car Steering Wheel So Heavy? 5 Common Causes and Fixes
A car's steering wheel must be relatively light and responsive when necessary. If your steering feels unusually heavy, don't try to ignore it. Although a heavy steering wheel may seem like a minor issue, it can often result from something as simple as bad wheel alignment or something more serious in the steering or power-steering system.
As an Indian driver, you are well aware that roads can be bumpy, dusty, hot, congested and full of potholes, which means you have to spend plenty of time on the road, even in bad conditions. Therefore, it often becomes essential to understand what may be wrong with your car in a specific situation and how you can get the problem fixed without spending too much.
The good news is, you probably don't have to replace critical systems right away. A few basic checks should fix most of the problems associated with abnormally heavy steering.
1. Bad Wheel Alignment
The first thing to check when your car's steering feels heavier than usual is the wheel alignment.
Your car's front-wheel alignment affects how easily you can turn the steering wheel and helps keep the vehicle stable on the road. It is crucial to get the alignment done when it is off because roads in India are not perfect, and the car pulling to one side can cause uneven tyre wear and put extra stress on the car's components.
It is entirely possible that you recently hit a big pothole or kerb and noticed that your automobile had a change in the way it behaved. Getting the alignment done should resolve most of these issues, and it may prevent you from spending more money on other steering-related problems unnecessarily.
2. Low Power Steering Fluid or a Leak in the System
If you have a car with power steering, the problem may be caused by simply having low power-steering fluid. If there is a leak in the system, just adding more fluid without determining the cause of the leak is not enough.
You can check the power-steering fluid level according to your vehicle's owner's manual and bring it to the recommended level. However, if you notice that the level keeps dropping, you must get your car checked by a professional mechanic. It is necessary to use the appropriate power-steering fluid for your vehicle.
3. Old or Contaminated Power-Steering Fluid
Another factor you must consider while diagnosing power-steering problems is the age of your power-steering fluid. If you drive an older car, you should consider this to be one of the possible causes of power-steering issues, especially if you haven't been maintaining your car regularly.
Old fluid can cause problems in a hydraulic power-steering system. Ask your mechanic to check the fluid if your car has been in service for a long time and the fluid has not been changed according to the recommended maintenance schedule. However, keep in mind that just replacing the fluid may not be enough to stop your steering wheel from becoming heavier. After resolving this issue, you should ask a mechanic to inspect other possible steering faults.
4. Steering Rack Issues
If none of the previously mentioned causes are responsible for why your car's steering feels so heavy, it may be necessary to get your car's steering rack repaired or replaced.
The rack-and-pinion system transfers steering input to the front wheels, and if there are issues with the steering rack, it can affect the car's turning ability. The steering rack may be damaged or worn and may need to be repaired or replaced, depending on the situation.
It is essential to leave this task to a professional because it is not cheap to replace the part, and you must not be in a hurry to spend a significant amount of money on repairs if the issue is something minor. The mechanic will be able to inspect your car's steering system and let you know what the problem is before suggesting a suitable course of action.
5. Power Steering Pump/Drive Belt Issues
For cars that require power steering, the power-steering pump is one of the most critical elements of the system. The pump can malfunction, making the steering stiff and difficult to turn.
Your car's power-steering pump may also be damaged, especially if the drive belt that runs it is loose or worn out. A professional mechanic can inspect the power-steering pump and check whether it is functioning properly. This is especially important if you experience strange noises coming from the pump and notice that your steering wheel suddenly becomes harder to turn.
What To Check First?
If your car's power steering feels heavier than it should, there is no need to jump to any conclusions. Instead, go through these simple diagnostic checks in the exact order mentioned below.
- Get your wheel alignment checked.
- Ensure that the power-steering fluid is not low (if applicable).
- Check for any signs of leakage in the power-steering system (if applicable).
- Check the condition of your power-steering fluid (if applicable).
- Have a mechanic inspect your steering rack.
- Have a mechanic check your power-steering pump.
- Get your drive belt inspected (if applicable).
Following this procedure will allow you to identify most minor issues and avoid spending too much money on steering repairs.
