I just purchased a 2001 Ford Expedition Eddie Bauer. I had a 99 just like it but it was totaled in an accident. The only difference is that the 01 has the air ride suspension on it. I am not sure I am liking it too much. It makes the truck sit low like a 2WD. Sometimes when it is pumped up, the rear sits a bit lower than the front??? Is any one familiar with these or have any suggestions? Should I switch it to regular suspension and how much would this cost?
