I have a 2006 CC 4x4 BT with PRG leveling kit.My truck has 25,000 miles on it and I have had the leveling kit since 1000 miles with no problems.In the last week,I've developed a noise.Every time I accelerate quickly from a stop or hit the brakes quickly,I hear a creaking/popping noise. The noise seems to coincide with the trucks front end dipping and raising with acceleration/braking.Definately sounds like it is suspension related on the driver's side.Feels like I can feel it in my feet when driving.Any suggestions on how to troubleshoot?
