Mine failed at 112k miles. It was definitely shot. I wish I had taken a picture but forgot to. I think what happened, at least in my case, is that the needle bearings and carriers wear and that allows too much fore-aft movement. On my eccentric, the toothed gear part that the servomotor engages had been riding up against the bearing journals. The thing was quite scored and grooved.
