The steering wheel of your Porsche is a critical part in the overall functionality and safety of your car. It follows then that it must always be working properly with no lag when turning. A hard-to-turn steering wheel not only makes your ride uncomfortable but presents significant safety risks. Here are some of the reasons why your steering wheel might be hard to turn.
If you find that you can’t turn your steering wheel easily, the first culprit is usually tire pressure. Because this is the easiest to verify and fix, you should start here when you notice a stiffened steering wheel. Tires should be inflated to the recommended psi as per your Porsche owner’s manual. Check as well for uneven tire wear. If some of the tires (especially the front ones) are unevenly worn, that might be the reason why the steering wheel is stiff. Uneven wear suggests wheel alignment issues so make sure you take your car for wheel alignment.
Faulty Steering Rack
The steering rack of your Porsche is a system of joints and pinions that connects your steering wheel to your wheels. These joints and pinions are moving parts and over time, they become worn out and don’t move as easy as they used to. This then creates the stiffened steering wheel that you will notice as you drive. The easiest way to diagnose a bad steering rack is when the wheel is hard to turn when you start the car but eases after some time after the lubrication warms up.
Bad Serpentine Belt
The serpentine belt is a belt that is used to drive several engine functions such as the alternator, power steering pump and so on. Serpentine belts get worn-out over time and when this happens, one of the first things you will notice is that that steering wheel will become stiff and hard to turn because the power steering pump is not working properly. If not replaced, a worn-out serpentine belt will eventually break and bring the car to a complete halt.
If your power steering fluid is leaking, you will have a problem with the steering wheel. This is because the leak lowers the pressure in the hydraulic system causing less power to be transferred through the steering system. The result is an unresponsive steering wheel that gets worse as the fluid drains out of the system.
Power Steering Pump Malfunction
The power steering pump is driven by the serpentine belt and a fault here could also affect your ability to steer your car. If all other things mentioned above are fine, the culprit is usually the power steering pump. Replacing it usually solves the problem.
These are some of the top reasons why you might have difficulty with the steering wheel of your Porsche. Some of these can be easily fixed by a trip to a tire center while others might require a Porsche expert to fix the problem.
