feels over bouncy on rear susp, has air ride,even when syst, off , height is ok?

What is your question?

normal driving feels like rear shocks are gone, but has the air ride system, bounces at least 4-7 times just rolling over speed bumps ?turning corners at speed make the rear end jump . the truck looks level no leaks, compressor can not hear running? feels like my 67 g,t,o, back in 70`s jacked upand hard bounces,but navigator bounces soft and smooth, several times. system is currently turned off and nothing changed, any idea`s dealer ship has no clue its ok for them, but if i want a bouncy ride i`ll go to busch gardens....or mickyland......
