What Causes the Steering Wheel to Become Heavy?

[LeKate]

Steering wheel becoming heavy is mainly caused by insufficient power steering fluid and low tire pressure. The detailed reasons and solutions are as follows: Insufficient power steering fluid: Generally, the feeling of steering weight is relatively constant. If it suddenly becomes very heavy one day, or gradually becomes heavier, it could be due to dirty power steering fluid, similar to engine oil, which needs to be replaced. Alternatively, if there is a leak and the fluid level decreases, the power assistance will also decrease, making the steering wheel feel heavy. In this case, timely maintenance or adding/replacing the power steering fluid is necessary. Low tire pressure: Low tire pressure increases the contact area between the tire and the road surface, leading to increased friction and greater difficulty in steering, resulting in a heavy steering wheel, which is not conducive to driving safety. In this situation, the tire pressure should be replenished promptly.
