Leaking rear air bags

Hello, I'm Danny.

Before I can help diagnose is your truck a 2wd or 4wd? Also it would help to know if your engine displacement is 4.6L or 5.7L. Look forward to hearing back from you and thanks for using 2CarPros.

Yes, the air bags go out all the time on these. you can do it yourself, just get the new airbags and disconnect the battery or turn the suspension switch off. here are the instructions and diagrams below to help you get the job done. Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.
