Chery Tiggo 8 Pro 4WD transfer case noise under load
A grinding or humming noise from the transfer case when the 4WD system engages under hard acceleration or when cornering. The issue is most common on AWD models and is caused by transfer case fluid degradation. Changing the transfer case fluid with the correct Chery-specified fluid resolves the noise in most cases. Inspect the rear differential oil level simultaneously.
