Answer 1

Explanation:

Heavy steering:

Heavy steering refers to when the steering wheel of your vehicle becomes stiff, making it difficult to turn.

Causes:

Tyre pressure: If your tyres are not pumped up to the recommended air pressure, this can cause heavy steering. This is especially common in underinflated tyres, as it can mean the grip between the tyre and the road surface is compromised due to incorrect tyre pressure, and steering becomes more difficult.
Wheel alignment: If your wheels are not aligned properly, this can also affect steering. If the front-end alignment is out of place, this can lead to uneven tyre wear on the front tyres – making the vehicle pull to the side, which can create heavy steering.
Lack of fluid oil: Lack of fluid oil in your vehicle, or fluid leakage, can lead to heavy steering. If there is a lack of fluid oil or a leak, this can reduce the pressure in the system, meaning the steering wheel does not receive enough supply of fluid to perform freely.
Thick fluid oil: On the other hand, thick fluid oil can lead to problems, too. Powering steering fluid can collect debris and dirt over time, which can mean it becomes too thick to flow freely and lubricate all parts of the system. This is a common cause of heavy steering at low speeds.
