What Causes Vehicle Body Shaking When Driving on Smooth Roads?
2 Answers
Reasons for vehicle body shaking when driving on smooth roads are as follows: Tire-related issues: If slight shaking or deviation of the vehicle body is noticed during driving, it is generally caused by tire problems. The first possible cause is poor tire balance, requiring the owner to promptly perform a four-wheel alignment and dynamic balance. If the vehicle does not pull to one side, a tire dynamic balance may suffice. Deformation of tire rims: This is caused by deformed rims, necessitating inspection at a professional repair shop. This condition typically occurs in vehicles that have been in use for a long time. Generally, when replacing new tires or rims, a tire balance should be performed; otherwise, uneven weight distribution can easily lead to steering wheel shaking. Body shaking affects both driving comfort and control judgment. Deformed drive shaft: This is caused by an unbalanced and deformed drive shaft, a condition more common in vehicles that have experienced chassis collisions.
I was driving my car on a flat road when the body suddenly started shaking like it was on a massage chair, which was really annoying. The most common cause is tire issues, such as uneven tire pressure or imbalance, leading to unstable wheel rotation. I've experienced this before—after checking, I found the rear tire pressure was too high, and releasing some air solved the problem. Additionally, aging or deformed tires can also cause shaking. It's advisable to regularly check tire pressure, ideally using a home tire pressure gauge monthly, ensuring each wheel is within the recommended range. If the shaking feels like steering wheel vibration, it might be a wheel balance issue requiring a dynamic balance treatment at a shop. Ignoring this problem for too long can accelerate wear on other components and increase fuel consumption, costing both money and peace of mind. In short, starting with a simple tire pressure check can save a lot of trouble.
