Question About Factory Air Ride/Level System
'06 Yukon XL Denali pkg.
Something seems to be failing with the air leveling system. It works fine for day to day use, road trips and loaded up with kids and costco supplies. When I put a trailer on, empty flat deck car hauler, it levels out just fine. When I put a car on the trailer the pump comes on but does not go clear up to ride height and after driving a short distance it actually looses height to the point where the safety chains are dragging.
Where should I start?
