Why does the vehicle feel unstable and shaky while driving?
2 Answers
There are several specific reasons why a vehicle may feel unstable and shaky while driving: 1. Loose or damaged engine mounts: Engine mounts are the connecting components between the engine and the vehicle, ensuring a secure connection while reducing vibrations produced by the engine. When these connections wear out, vibrations in the car can be felt. 2. Uneven tire pressure: If the car feels particularly shaky at high speeds, especially noticeable in the floor and seats, it may be due to uneven tire pressure or unstable tires. 3. Warped brake rotors: If the car shakes noticeably during braking, such as unstable steering wheel or vibrating brake pedal, it is likely because the brake rotors have become warped. Warped rotors increase friction with the brake pads, or insufficient brake lubrication can make braking feel laborious and cause the car to shake.
Sometimes when I'm driving, I feel the car swaying back and forth, which is really annoying. The main reasons could be related to the tires or suspension. For example, incorrect tire pressure—too high makes the ride bumpy, too low makes it sluggish, and uneven tire wear can also cause swaying, especially with old tires that have uneven tread. Suspension system issues are a big problem; worn-out shock absorbers or loose ball joints can make the car bounce and feel unstable over speed bumps. Also, damaged wheel hub bearings can cause strange noises and make the car shake. I remember once on the highway, the car was shaking so badly it almost caused an accident—later, I found out the front suspension ball joint had come loose. Regular checks on these parts are crucial. Check tire pressure weekly and get a wheel balance test at the shop every six months to prevent accidents. This makes driving much more stable, and my family feels more comfortable riding in the car too.
