My 05 Denali is riding rough and very bouncy. Anybody exoerience this and what was the fix? I kno its an air ride suspension issue. Jus tryn to narrow down the troubke shooting
Look for a control box around the rear axle. It should be on the body and has a arm attached to the axle. When the truck is loaded and the rear sags, it pumps the air ride up. It's supposed to release air when it's too tall.
