Steering Wheel Shakes When Accelerating?
2 Answers
Acceleration-induced steering wheel shaking is typically a wheel-related issue. Here are the specific explanations: 1. First check the tire pressure of all four wheels: whether the two front wheels and two rear wheels have consistent pressure. If tire pressure is normal, then it's a dynamic balance issue requiring four-wheel alignment. 2. Possible poor tire dynamic balance. 3. Possible steel rim deformation. 4. Possible half-shaft dynamic balance issue: especially in repaired accident vehicles with unreplaced half-shafts. 5. Possible damage to the half-shaft intermediate bearing. 6. Possible wheel hub deformation: usually the wheel bearing would fail before hub deformation occurs, but this possibility shouldn't be ruled out.
I've experienced this before - the steering wheel shakes violently when speed increases, most likely due to improper tire balancing. When weight distribution is uneven during wheel rotation, the vibration gets transmitted to the steering wheel at high speeds. Check if the rims are deformed (like from hitting curbs during normal driving) or if there's uneven tire wear, as these could be causes. Also inspect for loose suspension or steering system issues. I recommend getting a tire dynamic balance check at a repair shop first - it's inexpensive and straightforward. Don't wait for a highway emergency, addressing it proactively is safest. Tire imbalance not only affects driving comfort but also increases fuel consumption. Regular maintenance can prevent this issue.
