I'm running UD60's with 40x13.50 Nitto Trail Grapplers mounted on KMC Machetes which are 17x9 and 3.5" back space. I'll post a straight on shot in the morning along with the outside to outside measurement.

I have been looking at these and there is one piece of info that I can not find. Maybe someone here knows.
On the front UD60, is there additional caster and pinion angle built in. I found that the Dynatrac 60 has 10 degrees of angle between the pinion and the C's so you can keep a decent caster angle and still point the pinion up based on your lift.

From the factory, these use a clicking style jam nut that makes clicking sounds as you torque it. I believe this style of nut was found on some early Dana 70s and has a larger diameter than a traditional locking nut. I was on the phone with Randys/Yukon for quite some time trying to figure out why my jam nut was repeatedly loosening itself and why the spring from the lock out hub was getting jammed between the inside of the hub and the spring retainer. They determined that the Yukon hubs are not compatible with this style of nut and that I need to switch over to a conventional locking nut which they sent. I havent had an issue since then but I will be checking intermittently to make sure it is still tight.

The issue people were having was due to the hubs not being fully seated when torqued. New hubs have tight seals. Dana has a machine that presses the hubs on before torquing. What happened is that the machine was not stroking far enough and therefore was not fully seating the hubs (that issue has been resolved, but assume it can effect anyone with UD60s up until very recently). There are different torque procedures depending on how the new hub is installed. With it not fully seated, there was a good chance the torque process would not fully seat the hub. Those are people who had axles show up with loose hubs, or it occurred during the first couple thousand miles(usually).
