What causes steering wheel vibration when a car reaches 110 km/h?
2 Answers
There are several reasons why the steering wheel vibrates when a car reaches 110 km/h: Vibration caused by collision: Collisions can deform the steering tie rod and steering cross rod, wear out various ball joints, or cause irregular tire wear, leading to an increase or decrease in toe-in. Damaged steering damper: A damaged steering damper, oil leakage, or deformation of the front suspension springs can also affect stability. Bearing wear: Loose wheel hub bearings or severe wear of the left and right steering knuckle ball joints can result in inaccurate front wheel alignment. Loose transverse thrust rod ball joint: A loose transverse thrust rod ball joint or a loose bracket can cause unstable driving. Unbalanced wheels: Unbalanced wheels, or the loss of balancing weights on the original wheels, can cause the front end to wobble during high-speed driving, leading to steering wheel vibration.
When the steering wheel shakes at a speed of 110 km/h, this is a common issue I've encountered in my years of driving experience. Most of the time, it's due to improper tire balancing, causing the wheels to become unbalanced and shake under high-speed centrifugal force. It could also be due to damaged or deformed rims or tires, such as from hitting a pothole or uneven tire wear leading to irregular tread. Aging suspension components like shock absorbers or loose control arms can also transmit vibrations to the steering wheel. Don’t underestimate this problem—it reduces handling and increases the risk of accidents, which could be serious if control is lost. I recommend visiting a professional shop for a comprehensive inspection, focusing on wheel alignment and balancing tests. Also, check if the brake discs are even, as warped front discs can easily cause shaking at high speeds. Safety first—avoid high-speed driving and address the issue as soon as possible.
