4MATIC and driveline isolation
Driveline vibration or binding can originate in tires, wheel bearings, axle joints, prop shafts, differentials or transfer-case components. Confirm tire sizes and rolling circumference, then distinguish steering-angle-related binding from speed-related vibration and load-dependent noise. Inspect mounts and joints, review relevant chassis fault data, and avoid assuming a transfer case is defective based on a shudder alone.
Repair decisions and verification
Road-test after repair at the same speed, steering angle and load that reproduced the original symptom.
Tire scrub, vibration or binding at low speed may relate to tire differences, suspension geometry, driveline components or control-system behavior.
How the problem should be evaluated
Check tire specification and wear, confirm whether the symptom occurs only at full lock, and inspect drivetrain and chassis fault data.
Why the model and engine matter: Avoid assuming that a transfer case has failed without confirming the source.
