What is the solution for vehicle shaking between 130 to 140 km/h?

It is likely a tire dynamic balancing issue. Here is more information about dynamic balancing: 1. Function of dynamic balancing: Vehicle dynamic balancing refers to the balance between wheels during driving. To prevent unbalanced states caused by uneven mass distribution of components during vehicle operation, dynamic balancing is required. 2. Benefits: Regular balance testing can not only extend the service life of vehicle tires but also improve driving stability, avoiding traffic accidents caused by tire wobbling or bouncing at high speeds that lead to loss of control.
Experiencing whole car vibrations at speeds between 130 to 140 km/h is quite troubling. First, check the tire balance as unbalanced wheels are a common cause. I recommend visiting a professional repair shop for a dynamic balance test—simply adding or adjusting the lead weights should suffice. Also, inspect the four-wheel alignment since incorrect alignment can cause the car to shake at high speeds. The suspension system needs attention too; worn-out springs or shock absorbers can increase vibration risks. For rear-wheel-drive vehicles, the driveshaft might be worn or bent, requiring replacement. Don’t overlook brake disc issues—uneven surfaces can also cause vibrations. Safety-wise, high-speed vibrations can lead to loss of control, so I advise slowing down immediately and getting it fixed as soon as possible. Regular wheel maintenance can prevent such problems. Lastly, loose engine mounts might be the culprit—check and tighten the bolts. A comprehensive approach is essential for a hassle-free solution; spending a bit now saves trouble later.
My car shakes violently when reaching 130-140 km/h on the highway, making it hard to hold the steering wheel steady. To fix this, I prioritize getting the tires balanced—a quick one-hour job at a repair shop. If that doesn’t work, I check the wheel alignment next, as misalignment can cause shaking, and correcting it often brings immediate improvement. It’s also important to inspect suspension components, such as ball joints or bushings, as wear in these parts can amplify vibrations at high speeds. From my experience, if the wheels have been modified and not properly balanced, this can also happen, requiring recalibration. Another possible cause is an unbalanced driveshaft, especially in older cars, necessitating part replacement. For prevention, I get my tires balanced every six months to ensure even wear. If shaking occurs at high speeds, I safely pull over and contact a professional mechanic immediately—delaying repairs risks further damage to the vehicle.
When the car shakes at speeds of 130-140 km/h, unbalanced tires are usually the main culprit. I recommend starting with a wheel balancing test, which can be quickly resolved at a repair shop. If the shaking persists, check for wheel alignment deviations—adjusting the angles should stabilize the ride. Also, inspect the suspension system, as damaged shock absorbers or control arms can increase vibrations. Regular maintenance can prevent such issues, and a simple check of tire pressure consistency helps. For safety, high-speed shaking is hazardous, so slow down immediately and address the problem.
