2008 Yukon hybrid, I hear several strange clicking noise when I am accelerating, and one or two click same sound when I am braking. I took it to dealership, they claim the entire drive shaft need to be replaced. The sound of the clicking sounds like electric arcing, but definitely not an electrical issue. There is steel mesh housing over the coupler on the drive shaft, not sure if the sound is coming from it.
Anyone had similar issue with clicking sound when accelerating or braking?
