Welcome to the garage.
Did you already check the fluid levels in the differentials and the T-case? I would also take a small sample of the fluids after driving a bit to see if there is any sign of metal flakes or glinsters. Check the front and rear propeller shaft joints (CV or U) for damage and play and the front drive shaft CV boots for cracks
