What Causes the Steering Wheel to Become Heavier?

The reasons for a heavier steering wheel include issues with the power steering fluid, overly tight bearing alignment, and problems with the power assist unit. There are three key points for proper steering wheel usage: 1. Place both hands firmly on the left and right edges of the steering wheel: Grip naturally with fingers curled inward and thumbs extended straight along the wheel's edge, avoiding bending them inside. This grip positions the right hand closer to other controls for easier operation. Additionally, when the right hand operates other controls, the left hand can still effectively steer. 2. When turning the wheel, coordinate both hands with appropriate force: Use one hand as the primary mover and the other as support, pushing or pulling as needed. For a left turn, the right hand pushes left as the primary mover while the left hand pulls in support. When correcting the wheel after entering a new path, the right hand can again lead the return. 3. For continuous steering, alternate hands: For a sharp right turn, the left hand pushes right to the 1-2 o'clock position while the right hand pulls or slides a distance before quickly releasing and crossing over the left elbow to grip the 9-10 o'clock position, taking over as the primary mover. Simultaneously, the left hand rotates clockwise to the 5 o'clock position and pushes left. This alternating motion speeds up the turn. To straighten the wheel, reverse these actions accordingly.
I've encountered the issue of a heavy steering wheel many times over the years of driving, mainly due to problems with the power steering system. For example, in hydraulic power steering systems, insufficient power steering fluid or leaks, or a faulty oil pump can cause the power assistance to fail, making the steering naturally heavier. In electric power steering vehicles, it's more common for the motor or sensor to malfunction, reducing the assistance. Low tire pressure can also increase friction, leading to heavier steering, so it's important to check tire pressure regularly. Worn suspension components like ball joints or loose steering rods can also affect steering smoothness. Incorrect front wheel alignment can add to the steering burden. Ignoring these issues can cause greater damage to the steering system over time and affect driving safety. I recommend getting a professional inspection immediately; replacing the fluid or repairing the components can make steering much easier.
With over a decade of car repair experience, I can tell you that heavy steering is often caused by minor issues. The most common culprit is power steering fluid problems – either an empty reservoir or degraded fluid quality leading to poor pump performance. Checking the fluid level and topping up with fresh fluid usually solves it. Low tire pressure is another major factor; insufficient pressure increases tread friction, making steering laborious – a quick check with a pressure gauge does the trick. Worn or loose tie rods or suspension arms can also increase steering resistance, requiring tightening or replacement. Sometimes, it's just misaligned front wheels needing a wheel alignment to restore smooth handling. Regular maintenance of the power steering system and tires prevents small issues from becoming major repairs, saving both money and hassle.
When I was a young driver, I also experienced the steering wheel becoming heavier. It turned out to be due to low tire pressure, and the situation improved immediately after inflating the tires. Another possible cause could be a failure in the power steering system, such as hydraulic fluid leakage or a malfunction in the electric power steering motor. First, check the tire pressure; if that doesn't solve the problem, take it to a repair shop to have a mechanic inspect the steering system. Don't ignore the issue for too long, as it could make steering more difficult and affect safety. In short, maintaining good vehicle condition can help avoid such troubles.
