How to Solve the Buzzing Noise from the Teana Differential?

[SanClaire]

The solutions for the buzzing noise from the Teana differential are as follows: 1. Insufficient lubricant or poor gear meshing causing noise—simply add lubricant. 2. Loose active gear bearing or differential bearing causing abnormal noise—replace the components. 3. Worn differential planetary gears or worn half-shaft gears and washers causing abnormal noise—replace the washers or components. Specific causes of differential noise: 1. Prolonged use of differential oil. Differential oil has a service life and needs to be replaced after a certain mileage; otherwise, the lubricating effect will drastically decline, leading to differential noise. 2. Severe wear of differential gears. When the gear wear is significant, it becomes difficult to match other internal components, resulting in a buzzing noise during differential operation—replace the gear. Additionally, improper gear spacing adjustment can also cause differential noise and requires readjustment. 3. Foreign objects on the differential. There may be foreign objects on the differential, which should be carefully inspected and removed if found.
