What Causes the Steering Wheel to Suddenly Become Stiff?

[MacLiam]

There are many reasons why the steering wheel suddenly becomes stiff. Here are the details: The reasons for the steering wheel suddenly becoming stiffer include: Insufficient tire pressure, contaminated power steering fluid, internal failure of the power steering system, poor bearing lubrication. How the steering wheel works: Steering wheels are categorized into single-spoke, dual-spoke, three-spoke, and four-spoke designs. Their working principle involves transmitting torque to the rack-and-pinion mechanism, thereby pushing the wheels to turn left or right. Solutions for a suddenly stiff steering wheel: Refill the hydraulic power steering fluid, replace the circuit fuse, replace the flat bearing, replenish the kingpin grease, and add lubricating oil to the tie rod ball joints.
