What Causes Vehicle Shaking Between 80-100 km/h?

[Gayle]

The reasons for vehicle shaking between 80-100 km/h are: 1. Poor wheel balance, abnormal tire wear, or damaged components; 2. Loose suspension or incorrect wheel alignment, requiring inspection of engine rubber mounts, shock absorber components, and suspension bushings for damage; 3. If shaking occurs during braking, it may be caused by uneven brake disc surfaces, which can be resolved by resurfacing the brake discs. Solutions for vehicle shaking: 1. Clean the fuel system and check if the idle control valve has carbon buildup that needs cleaning; 2. Inspect the condition of spark plugs, high-voltage wires, and ignition coils, checking for excessive carbon buildup on spark plugs and replacing them if necessary.

I've been driving for many years and often encounter shaking at speeds between 80 to 100 kilometers per hour. This is usually caused by tire imbalance, wheel rim deformation, or uneven tire wear, which can lead to vehicle resonance at this speed range. Additionally, issues with the suspension system, such as aging shock absorbers or loose ball joints, can also make the car unstable. I recommend first going to a repair shop for a tire dynamic balance test. If that checks out fine, then inspect the suspension components. Safe driving is crucial; don't push through severe shaking as it can affect braking efficiency or accelerate tire wear. Regular checks on tire pressure and wheel rim condition can effectively prevent similar issues. From my experience, addressing problems early saves money and ensures safety.

My car is a family sedan. Last month, when I was driving on the highway at around 90 km/h, the body started shaking violently, so I immediately took it in for repairs. After inspection, they said there was an issue with the suspension system, such as a leaking seal on the front shock absorber, which amplified the vibrations at certain speeds. The technician also mentioned that uneven brake discs could cause shaking in this speed range. Now, during every maintenance check, I have them inspect the suspension components and brake discs to ensure safe driving. If you encounter a similar situation, don’t panic—start by checking simple things like tire balance, but for a more thorough diagnosis, it’s best to visit a professional shop to inspect the suspension and prevent minor issues from turning into major problems.

Body vibration between 80 to 100 kilometers per hour is mostly caused by tire imbalance, or wheel hub/tire deformation which triggers resonance. Another possible reason is uneven brake disc surfaces, especially noticeable when braking at this speed range. It's recommended to perform tire dynamic balancing adjustment promptly, while having technicians inspect the brake system for evenness. Maintain uniform tire pressure routinely to prevent unexpected vibrations at high speeds.
