03 Navigator air suspension

I have an 03 Navigator, and whenever i shut off my car, the front suspension drops like right away. It used to drop really slow, and now its dropping faster than before. Also, when it pumps air into the suspension when the car is running, it pumps more air like 10 minutes later. I know there is a leak, but do not know where to start. I used a versus scan tool to see if there are any codes (B and C codes) and there is none.

It could be an internal leak but to check for an external leak, you could try spraying soapy water on all of the lines, fittings and airbags.

Hey msrdude,

One great possibility is the o-rings on the air struts. As Bert says, I would consider getting a sponge and some soapy water and applying liberally to the front air struts and letting it air up while watching for bubbles. Otherwise, I think there is also a "T" in the air lines from the compressor that can also leak or possibly a problem with the strut mounts allowing air to leak from that region.

Re: 03 Navigator air suspension

ok, for the front dropping after the car is shut off is normal. according to the owners manual, it drops to let the people exit the vehicle easier. Must have heard the owner say that wrong.

Re: 03 Navigator air suspension

If there was an air suspension problem, would there be a trouble code?? Like a b or c code?
