AWD Vibration from Old Transfer Case Fluid
The most common X3 complaint we see in Malaysia is a vibration or binding sensation when turning sharply at low speed — in car parks and tight corners. This is almost always caused by degraded transfer case and front differential fluid. Fresh fluid typically eliminates this within one drive cycle. If vibration persists after fresh fluid, the transfer case clutch pack may be worn — ISTA inspection recommended.
