Having issues with your BMW X3's all-wheel-drive system? A worn or stretched transfer case chain could be the culprit, causing binding, vibration, or failure to engage 4WD. This MOCA replacement chain (part number HV-086) is designed to fit 2004-2010 BMW X3 models with both the 2.5L and 3.0L engines.
