My compressor for my Air Suspension has a loud almost grinding/knocking sound to it and it runs almost continiously. I have figured that the system has a leak in it. Is there a way to locate the leak if its in a line or in the airbags themselves, is this hard to fix, and where can I find instructions on how to fix this problem?
Get a spray bottle with water and a few drops of dish washing soap in it. Spray down the air bags real good and look for sudsing to indicate a leak. You have likely ruined the compressor by now so when you find your leaks, you will likely need to change the compressor also.
