There is no universal safe answer. A fault affecting only mode selection differs from a transfer case with low lubricant, damaged internal parts, or severe binding. Continuing to drive may worsen damage or lead to loss of drive.
Switching to two-wheel drive does not necessarily isolate a damaged transfer case because components may still rotate. Do not assume a mode change makes the vehicle safe.
Contact Certified Transmission at 527 SW State Route 7 Highway in Blue Springs for guidance. If you notice grinding, substantial leakage, binding, or unreliable movement, stop driving and arrange assistance.
