Wouldn't load levelers go back down?

[Bushman]

I was talking to a friend of mine yesterday who has a 2010 Hummer. She hooked up the trailer this fall and pulled it across the state and back. All well and good until she drove the Hummer into the garage and took out the top cross member of the garage door. Turns out that the suspension system automatically adjusts for trailer towing by blowing up the shocks or air bags two inches to compensate for the additional tongue weight. She was told that once they blow up like that, they don't go back down. Does this sound logical? My Buick has load leveling suspension too, but that seems to compensate all the time. Why would a new GM be any different?

Well it sounds like it stayed level, just a little to much on the high side. Seriously one would think there would be a sensor to tell it when the trailed was unhooked & then it should lower to normal hiegth. Might tell her to read the manual or talk to the dealer.

The leveling suspension on our '95 Ford Crown Victoria went back to normal after the trunk was unloaded or the trailer was disconnected.

I suspect since the Goverment now owns GM that this was a conspiracy to put people back to work.

This one small accident just gave a days worth of labor to a general building repeair man,garage door salesman,delivery man, auto body repair man, auto mechanic
and lets not forget all the people that made all the products each of these individuals used in the process of the repairs.

An interesting angle on that conspiracy theory. I stopped off at the dealership yesterday and talked with the service adviser. Yes, they should self adjust when the load is removed and he admitted that it sounded like a factory defect. I'll get more details on what happened this weekend, but it sounds like a BS explanation to a woman was easier than a warranty repair of a sensor and later a roof. Kind of a testament to what went wrong with GM in the first place.

Bushman I had to air-up my air bags in the motorhome and once air up then didn't go back down unless a leak was present. I once had a set of those shocks you could add air to via a small compresser but those were a real headache, always having line trouble underneath (plastic lines) so I replaced them with a good set of coil springs over the shocks.

Back in my misspent youth, I had a pumped up Mustang fastback that I added a whole bunch of parts to that didn't come standard from Ford Motor Company. The tires didn't fit in the wheel wells so I put on shackles to boost the back end up in the air. It looked cool to me, but the State Patrol pulled me over and gave me a warning to take them off. Probably a good thing too as it was spooky squirrelly at high speed. Anyway, air shocks were the only other alternative as I saw it so I put on a set of those. Worst shocks that I ever had because it was like riding on a board with no springs. I've decided that smarter guys than me designed cars and trucks at the factory, so I don't mess with them anymore.
