What Causes Steering Wheel Stiffness?

[McHarper]

The reason for steering wheel stiffness is that the power steering fluid is too dirty or there is air in the pipeline. Steering wheels are categorized into: single-spoke steering wheel, dual-spoke steering wheel, three-spoke steering wheel, and four-spoke steering wheel. Their working principle involves transmitting torque to the rack and pinion mechanism, thereby pushing the wheels to turn left or right. The method for turning the steering wheel is: 1. The grip on the steering wheel should have both hands positioned at the 9 and 3 o'clock positions; 2. Return the steering wheel to center after turning; 3. Hand movements should be balanced to avoid unnecessary shaking; 4. Eyes should look straight ahead, with the left hand lightly gripping the upper left of the steering wheel; 5. The right hand on the upper part of the steering wheel should grip lightly, and both hands should be relaxed, naturally hanging down; 6. The thumbs of both hands should naturally point to the upper part of the steering wheel, while the other four fingers should lightly grip from the outside in.
