What are the causes of heavy vehicle steering?

[Phil]

Reasons for heavy vehicle steering: 1. Insufficient power steering fluid; 2. Damaged bearings in the steering gear or steering column; 3. Lack of lubrication or damage to the tie rod ball joint; 4. Insufficient front tire pressure; 5. Too small engagement clearance between the steering pinion and rack. A series of devices used to change or maintain the direction of a vehicle's movement or reverse are called the automotive steering system. The function of the automotive steering system is to control the vehicle's direction according to the driver's will. The automotive steering system is crucial for driving safety, hence its components are referred to as safety-critical parts. Automotive steering systems are divided into two main categories: mechanical steering systems and power steering systems.
