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