Today was a great day to be home & work on the truck, no rain & normal summer hot weather; bug count was low too. The drivers side air bag had been removed last year, so removing it was a breeze. Replacing the bag into the assembly wasn't too bad & went well; reinstalled back into the truck & ready for the right side air bag removal. Several bolts were rusted STUCK on this assembly, so it was a bear to get them loose. To add insult to injury, the air line nut(it has a T on this side) had a split in it when found. Even the old air bag nuts were severely rusted to the studs, to the point that a 6point wrench or socket just spun on them. It took a while to tear this mess down & put it all back together, but it was accomplished. Putting the air lines back on, the brass nut split in two, so I put a couple of plastic ties on it to hold it to move the truck back to its parking location. It actually held & didn't leak(yes, I will replace it) for the 15 minutes I ran it. When initially running the startup, the cab airbags inflated & moved the cab upward a few inches, which I have never experienced before. Upon shutdown, there was no longer that loud hissing of the airtanks dumping thru the leaking air bags. Now, the system actually works as designed & the gauges show higher air pressure retained in the tanks during operation & after shutdown. I would call this a successful repair session on the airbag system.
