Found a small leak at the transfer case under my wife's X5. The actuator mounting surface is weeping. So I ordered two kits from ECSTuning, a rebuild kit for the actuator which includes the mating gasket and a new gear. Plus a fluid replacement kit with fluid, new plugs and sealing washers. Planning on doing the work as soon as the parts get here. Looking forward to seeing if ECS's shipping department has improved like I've heard. This work also requires resetting the adaptations in the control module so I will have to borrow the correct tool from my BMW tool source.
Sure glad I live in the desert, no salt, no moisture, like in the other posts. All we have is a lot of sun which is hard on the paint and exterior plastics like headlights, especially since I have to keep my cars outside.
