I have a set of the superwinch freewheeling hubs. that i bought new last summer. They look great. and work even better.

my dualmatics have lasted for 40 years or so without failure. I think that's relatively durable. I have a set of Warns, too, and haven't had any problems with those either.
Strength is relative. If you compare the internal mechanism to some of the other hubs you can tell they are not as strong. Ive seen several broken examples of most common types of locking hub. Just a few more dualmatics (and faireys) than the others. Doesnt mean they wont or dont work.

I still sense you haven't gotten an answer to your question: The 'when' & 'what' part.
The AWD Outback and Fulltime 4WD Discovery are the same, Just different terms. Selectable 4WD drive systems don't have center differentials. When you select 4 WD, you are shifting transmission (via transfer case) power to the front driveshaft. Equal power is now going to each driveshaft. Without front locking hubs (or more correctly, 'unlocking hubs) even in 2wd, your front wheels will be turning you front axles, differential, and driveshaft. This is unnecessary wear to a slight degree, but also an unnecessary waste of energy. Unlock the hubs, and you aren't wasting engine output to make the truck move dead parts (in thick oil up here in New England)
Dualmatics came out with the CJ2A jeep, and were sufficient for that truck, and the 2.25 Land Rover. They won't handle much more than those two engines. They all do essentially the same thing: disconnect the wheel from the axle, but the engagement/dissengagement mechanism differs in all of them.
The original links that leafspring provided more than answered my original questions. Originally, I wasn't sure what I had and how they functioned, but now I think I have a pretty good idea how they function.
Thanks!

dam! that's sassy. i had unlocking hubs on my very strong V-8ed Scout, and it was recommended to use them. in first gear that Scout would pull a President off Mt Rushmore, so is the NADA 6cyl too much for the hubs Highmile has? aren't there Fairley ODs on a lot of Rovers, incl Sixs?Originally Posted by leafsprung
