Why does the steering wheel start shaking when the car reaches 80 km/h?
2 Answers
1. There are several reasons why the steering wheel shakes when the car reaches 80 km/h: 1. Loose ball joints in the chassis: When the vehicle is driving at high speed, there may be play, causing shaking. Check the ball joints and replace any damaged ones. 2. Loose steering column: Inspect the steering system and replace any damaged components if necessary. 3. Unbalanced wheels: Perform wheel balancing for the tires. 2. Below is an introduction to car maintenance: 1. Introduction to car maintenance: Car maintenance refers to the regular inspection, cleaning, replenishment, lubrication, adjustment, or replacement of certain parts as preventive work, also known as car servicing. 2. Scope of car maintenance: Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 3. Purpose of car maintenance: The purpose of car maintenance is to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life.
When driving on the highway at 80 km/h, the steering wheel shakes, and I've encountered this several times, which is quite concerning. Initially, I thought it might be due to uneven road surfaces or strong winds, but persistent shaking indicates a problem. The most common cause is tire imbalance, where the balancing weights on the wheels have fallen off or uneven tire wear leads to imbalance during high-speed rotation. It could also be slight wheel hub deformation, such as after hitting a curb, or a fault in the suspension system, like a loose control arm ball joint. If the shaking eases at speeds higher or lower than 80 km/h, it's likely a balancing issue. It's recommended to visit a repair shop as soon as possible to check the tire balance—usually, adjusting it will resolve the issue. Regular maintenance should include tire rotation and periodic balance tests. Don't overlook these minor issues; safe driving is paramount, as losing control could lead to serious trouble.
