    Anyone wanna play internet diagnosis (08 Yukon XL suspension noise)

    I tried putting it in Neutral while on the freeway a couple times-the noise stayed the same and didn’t change with the engine revs. I think part of it is the wind noise covers it up so I just can’t hear it. I think I feel the vibration as much as hear it, if that makes sense.
