What is the reason for the rattling sound when holding the brake in D gear?
1 Answers
Holding the brake in D gear and hearing a rattling sound can be caused by severe wear of the ball joint under the gear shift, which may require replacing the gear oil or the ball joint. The ball joint, also known as a universal joint, is a component in a car that refers to a mechanical structure using spherical connections to transmit power between different axes. The reasons for ball joint wear include: 1. Poor performance of the shift fork shaft, excessively small clutch travel, and severe wear requiring inspection of the corresponding ball joint movement position; 2. Excessive viscosity of transmission oil, excessive synchronizer wear, where wheel shaking, jumping, and swinging can be felt at low speeds, unresponsive steering, ball joint damage, oil leakage, rust, which is usually visible as damage to the ball joint rubber boot with oil leaking out, and stiff steering; 3. Degraded performance of the clutch pressure plate, excessive synchronizer wear, and reduced performance of clutch oil due to temperature effects.
