I have a set of 529 third members. I believe they both have Yukon gears
Front is welded carrier and has a couple of chips on some of the ring teeth. Works fine I have been running it for a while now without any issues. $200
Rear is in really good shape and has welded carrier as well. $200
I'm selling these so I can gear my elockers. Possible trade for gears and setup kits or $400
They are still installed in my axles. I will pull them if interested.
