What Causes the Abnormal Noise in Passat?

[LeVivian]

Passat abnormal noise causes are as follows: Test Drive Inspection: Through test drive inspection, it can be determined that the clutch inside the transfer case is damaged, resulting in obvious shaking when the steering is turned to the limit. Component Damage: The malfunction is mainly caused by damage to the internal differential or clutch, leading to the issue. The primary symptom is mostly shaking, which often occurs severely during initial acceleration or when the steering is turned to the limit. Installation Adjustment: During installation, proper clearance adjustment is necessary to ensure the repaired transfer case functions correctly and completely resolves the shaking issue.
