2005 Lexus GX 470 • 80,000 miles

Hi, please I have a problem with my 2005 lexus gx470. It seems the height control is not functioning any longer and it bounces as the car moves through uneven roads. Please what can I do? Also when the car is started you hear some kind of noise from the rear right underbody as if there is being an air release somewhere.

Check fuses and checkfor broken or leaking air lines. Then have a pro look at it so he can scan it
