Less than 300 miles, they were on my jeep that i traded in. I have no intention of using them on my new jeep. They were greased when built and i greased them again at 100 miles for the break in. Comes with the 2 tcase flanges and the rear pinion flange. These were over 800 bucks with shipping. I'm selling for 575 shipped. Save some cash, pm me for details.
