Yes, you should switch the air suspension off when the truck is getting ready to be lifted this stops the system from lowering itself. The reason your mechanic told you to go to the dealer is because he does not have the tools to find the problem. You need to find someone with a bi-directional scan tool that will scan ford body systems. Then a self diagnostic routine can be run on the air suspension to find out what went wrong with your system. If your air suspension light is on there may already be a code stored. My advice is to take it to a ford dealer, better to lose an arm and a leg for a good repair then for parts you do not need and maybe no repair at all.

The mechanic mentioned that this was due to the air suspension and he said I should turn it off and back on that the car will rise back to normal within few days, however ther the car ride was so bumpy and shaking that I took the truck back to shop the next day. The mechanic told me that there is nothing he can do to the truck and suggested that I should take it to the dealer but I know the dealer will cost me a leg and arm even before taking a look at the problem. I am just curious if any of the expert of this forum has witness anything like this before and kjnow exactly what I need to look for, do or what might be the problem.
Please any help, suggestions, advise will be greatly appreciated.
Thanks and God bless you all... Just for future reference, so it is advisable to switch the air suspension off when the truck is getting ready to be lifted right?
