    air bags deflate overnight from time to time. Pump up right away and stay inflated. Annoying problem on a great truck!

    Noticed when i'm in a bumpy area the the truck hits it hard. There seem to be no bounce, the rear end dart quickly to one side which makes me feel like I'm gonna have an accident. The springs are very squeaky. My cousin took a look underneath the truck and he said the "airbags" were not inflated. I have not come to a solution for the problem because I'm getting my other vehicle repaired therefore I need one to drive.

    I had the same problem with my TBSS several years ago at around 60,000 miles. First problem was nightly deflating. Simple solution was to tighten all the air line fittings between the compressor and the bags. Second was the compressor gave out. I drove for a long time without the compressor (solving the air line leaks helped)then every once in a while, especially if the outside temperature dropped, I would "air up" the bags with an air hose.
    I finally bit the bullet and replaced the compressor and it's been fine for 36000 or so.
    One tip I'll suggest is not to use the compressor for long duration, like to fill a flat tire. I believe this is what killed mine.
    Good luck
