Buick Rainier Air Suspension Fix
Do a Google search....I saw a Utube video 6 months back where a guy showed the system and how to fix. I seem to remember that the bag GM used sometimes leaks at the top and can be taken out, cleaned and reinstalled. The other option is to change air bags to aftermarket type used by the truck and lowrider people. Look at a newstand magazine like "Truckin" and look at the ads for prices.
