Well, Friday, I stopped by the Warn booth at the Arena in Moab, and started talking with a guy about my always-loosening Warn Premium Hubs.
Turns out the guy was actually the Manager of Development, not some Marketing type. He put me on the phone with a guy at the factory, and we discussed it.
So the Warn solution (and they're sending this to me for FREE) is to remove the cap screws, and put studs in the (hmm, what's the name of that part?) axle flange, with "disturbed threads", and to put nuts on the outside, also with "disturbed threads".
I ALSO, have the Spidertrax Super Hub Bolt Kit
http://www.spidertrax.com/drivetrain_shb.htm - this kit has the drills and tap to put in LARGER cap screws. I haven't installed it yet.
So, I'm thinking of installing the Warn Studs on one side, and the Spidertrax Super Hub Bolt Kit on the other side, and give them a true side-by-side comparison.
If the Warn fix WORKS, I'll get the info so anybody can order it.
