What Causes Steering Wheel Vibration When Exceeding 120 km/h?
1 Answers
Speed exceeding 120 km/h steering wheel vibration reasons are as follows: 1. Caused by force feedback generated from tire-ground contact; 2. Various vehicle issues including wheel camber/toe misalignment, tire surface debris, lost wheel weights, deformed rims, excessive steering linkage play, or insufficient tire pressure. Specific tire-related problems include: 1. Uneven tire pressure among four wheels (especially front pair); 2. Uneven tread wear patterns (one-sided wear); 3. Out-of-round wheel rims (steel/aluminum rims deformed into oval shape); 4. Lack of alignment correction after tire replacement; 5. Tire puncture creating a bulge - unnoticeable at low speeds (absorbed by suspension) but generating pronounced frequency vibrations at high speeds.
