Why Does the Car Steering Wheel Suddenly Become Heavy?

[SanKarter]

Here are the main reasons why a car steering wheel suddenly becomes heavy: 1. For hydraulic power steering, check if there is a lack of power steering fluid or any oil leakage. If fluid is low, it needs to be replenished to the normal range. If the fluid level is adequate, check if the power steering pump belt is too loose. If it is loose, tighten the belt. Also, check if the fluid is too dirty, which can reduce its flowability. Generally, the fluid should be replaced every 2 years or 60,000 kilometers. 2. For electronic power steering, check if the fuse is blown and if there are any open circuits or short circuits to ground in the wiring. 3. Check the tire pressure, as a leak can also cause the steering to become heavier. If there is a leak, it needs to be inflated.
