I have 2 DCT diffs for sale. 3.15 gear ratio. One was bought as a refurbished unit, the other had 70k miles. They are not in great working condition, but they should be good with new flanges. Previous owner used wrong flange bolts that was just 2mm too long when changing the rear suspension geometry, so the flanges were slightly pushed in and making a slight contact with the diff housing. Both diffs still turn freely. It could be an easy fix if it’s just the cover on the flanges, or it can be a good unit for core replacement.. cost me 3 diffs to finally find the problem. I don’t have time to refurbish them so letting go for cheap. $500 each OBO, bundle deal if you take both. Located in Los Angeles.
