Toyota Sequoia vibration issue at 70-80 mph with intermittent steering wheel shake on Toyota Sequoia

Some Toyota Sequoia owners report experiencing vibration issues, particularly at speeds between 70 and 80 mph, accompanied by intermittent steering wheel shake. These vibrations are often attributed to unbalanced wheels, which are a common cause at high speeds. Additionally, some owners have noted that a bent rim, resulting from hitting obstacles like curbs or potholes, can lead to similar steering wheel shake. Problems with the stabilizer bar, such as broken bolts due to rust, may also contribute to vibration and noise in the steering wheel. Furthermore, damaged suspension components can cause shaking within the 60 to 80 mph range. If the vibration is speed-related and felt through the seat or feet, it could indicate issues with transmission mounts, u-joints, rear axles, or wheels. To mitigate these issues, it is advisable for owners to have their wheels professionally balanced and aligned, check for bent rims, inspect the stabilizer bar, maintain tires regularly, and assess the suspension system for any damage or wear.
