This video goes over replacing the rear air bags in a 2017 MercedesBenz GLS 450.
Over time the air bags will deteriorate and need to be replaced, they are a wear/maintenance item just like any other suspension component. Good thing these are easy to replace!
Don't pay a shop thousands of dollars and get ripped off for them to replace these. DO IT YOURSELF!
Follow this video just like so many others on the internet to show you how to do it. It's really so easy.
