I have a 2020 Peterbilt 389 car hauler. It’s obvious to me the sleeper has dropped down. I’ve had a couple of mechanics test the leveling valve/ air bags and shocks who’ve all said they’re okay.
I can tell by the rough/different way it rides, that something’s not right.
The bags appear to be holding air but could they be dry rotted and/ or maybe I just need new shocks and bags?
Anyone had any similar issues?
