Question about 2002 Oldsmobile Bravada
I'll assume you still have the air compressor which activates to automatically level your vehicle. When the air bags get old, they leak and need to be replaced. If you do not do it early, you will overwork the compressor and it will fail. Mine went out shortly after the air bags started leaking as it was coming on way too often. I got new air bags and a rebuilt compressor but the compressor failed within a few months. A new one was too expensive. I went to a website called Trailvoy.com and read about many that have had the same problems. One post explained how to cure this. So I chose not to mess with the compressor anymore and followed their instructions and made a bypass so I can fill the air bags myself from the air valve in the rear of the vehicle. I keep a portable compressor in the back just in case and it plugs into the 12v power port in the back. Pressure is best at 55 lbs. The air bags are rubber and eventually, due to weather conditions, they start to crack. If one is leaking, the second is soon to follow. When they can no longer hold air, the rear of the vehicle will sag way down and bounce when you drive it. It's not only annoying, it is unsafe.
