      Notice the shiny spot on the thrust bearing on the upper right side? Even though this turbo hadn't failed yet I believe it's efficiency was reduced by this as well as it was on it's way to failure because of that spot. That spot represents a high spot on the face of the thrust bearing caused by this bearing being dropped before it was installed (future pics show the dent in the outer edge). The high spot would have reduced the seal of the thrust bearing to the face of the turbo housing causing it to leak oil internally and also preventing the thrust bearing from laying perfectly flat against bearing housing thereby "cocking" the bearing in the grove of the thrust collar. This misalignment and less than ideal lubrication in the collar caused uneven wear on the collar stripping the chrome lining off and visibly uneven wear on the thrust bearing wear pads as shown in the upcoming pics.

      And as far as I can tell this turbo was never previously rebuilt so this damage is straight from Garrett.
