These parts where packaged well. Tolerances were pretty decent, pinion depth clearly marked for easy set up. I would buy these again if needed.

Fast delivery, well packed, easy to set up, and a very quiet gear set. There is no reason to spend more money than these cost - good value for a little over a hundred bucks!

very smooth, used old shims, bolted right up, oh used old bolts too, lock washers not a good idea, they need to change that, would not torque without mashing out washer, head to small on the bolts, bearings where wrong size, pinion bolt and washer wrong, other than that I was ok with the purchase because eaton made it up on their end.......... less than 700$ for pos rebuild eaton true trac best buy out there.....

Been driving with this for over a year and half, city, highway, and even some off-road, and about 15,000 miles. Absolutely no issues.
