Air Suspension Hissing - Please direct to correct thread

[Hellz]

so what are you askinn for here?

you selling the truck or looking to solve the problem?

for the problem..

the hardest part is going to be to try to locate the leak.
start it up and let the bags fill
(make sure it is in park with parking brake on)
go to the back and get underneath and listen for the leak.
you could also do the soapy spray bottle method and spray down all the lines.
if it is bubbling, then there is a leak.

If your compressor is contstantly running, it is only a matter of time before it burns itself out and that will add another $900 to the repair list.

so would be better to find the leak asap
