FWIW: After waiting about 3 months for them to arrive, I bought 2 reman units from Toyota for my '06 Land Cruiser, and I had to return BOTH of them in less than 100 miles. One's splines were so worn from prior use that they "clicked" in my new drive flanges, and the other one had a bad vibration. Like everyone else, I was excited to find Toyota axles at a greatly reduced price; however, in a very un-Toyota-like fashion, they weren't remanufactured to the level I expected from Toyota. Surprisingly, when I went to warranty them, I was told they were no longer available. The only thing I can assume is that they had many returned for shotty quality like mine and figured it'd be best just to sell new ones.
At the end of the day, I bit the bullet and bought new ones from Toyota.
