    Well, okay, but don't wait until the threaded holes get wallowed out and then will never hold tight.

    Mine got wallowed out. I used a combination of studs and bolts where i opened up the wallowed holes to the OD of the studs and used high strength thread locker. Mine get used all the time I drive my jeep as they are on the full float rear d44.

    Maybe why mine keep loosening? Might have started to wallow?
    I'll keep an eye on, until I can stud them!
    Thanks all.

    Well I take back my recommendation. Went to go repack bearings and all but 2-3 had sheered off inside hub on both sides. I have a full float rear, which I understand is more abusive on these....but it was disappointing.

    Looks like I am going the stud route as well..after I try to get the broken ends out.

    Well, here I am again missing several "warn" brand studs on my rear lockouts despite torqueing them to spec and checking after some miles. One side is fine. The other (the one that has always made a clicking/growling noise in low speed / high stress situations) is the one with the issue.

    I haven't checked to see if they are broken off inside the hub or not yet...I am going to have to figure out what to sacrifice to the jeeps gods before I check.

    Clean good condition threaded holes and using thread locker is key. I’ve had a full floater with external hubs for around 25 years and once I figured out to do this never had another problem. I also use nylon locking nuts to hold the locking hubs in place.

    Not sure how this is spelled , but the ' Nord ' style washers from McMaster - Carr is also the way to go. Along with Thread Locker ...... They've held very tight for me ?

    Yup, we have had this discussion before. If you look closely at your hubs, you will note that there aren't any threads in the first 1/4" of those bores. It is really important that whatever fastener you use has a solid shank going into that recess, be it bolts or studs. I've gone to ARP's 8740 bolts that torque to 45 ft-lbs and just use thread locker on them. Like Nick noted, the hub threads need to be CLEAN. Run a plug tap in them.

    These are what I'm using on the full float drive flanges.

    I used the same bolts on my new full floater but left the washers off (those bolts have tappered seats) since the axle flanges were counter sunk.

    I made the studs for the front hubs out of grade 8 bolts. The bottom of the blue tape is the lockout hub/wheel hub interface.

    I did the exact ARP bolts from Duffer's recommendation last year. I cleaned the threads with a tap, flushed them with brake cleaner, used red loctite, and torqued to 45 ft-lb. I have had no issues since:

    I appreciate all the options and can’t remember if I used thread locker or not last time. The nuts weren’t nylocs but were the aviation locks that have the little divots. The threads should have been pretty darn clean after having all the broken bolts removed from the prior time. I’ll report what I find and which way I go.
