I have a Dana 60 with a power-lock. I was told a couple of times that during a burnout only one wheel was spinning. When we took the trans apart the bolt in sprag was damaged and the case was damaged.

Could the power-lock slipping act the same as a drive line failure (shock) and cause damaged to the sprag?
