Lock-Rights?
Anyone using Lock-Rights in your BII? How about the front Dana 28 axle as well?
I do alot of snow plowing with my dedicated "Snow Plow Truck" a 1989 Bronco II 4x4. I recently became stuck numerous times in deep drifted snow and the stock open-differential set up just isn't cutting it. I'm debating weather to use one in the front differential. Will I have drivability concerns? As you may know, snow plowing requires many sharp turns constantly, sometimes working at the end of my driveway within the already plowed street which may not be snow covered. Will I break anything in the front axle under this severity? As you know with 4 wheel drive, turning is already effected slightly even in an open differential. I love the short wheelbase of the Bronco II, and wonder if adding a Lock-Right would effect the turning diameter as well.

No, you will snap the right outer shaft or twist it. I have managed that off road with just P235s and an open diff.
What will happen with the locker is you will leave ice and hit pavement and the sudden traction will snap or bend the ears on the outer shaft because there is no give.
A locker will effect your turning radius (front or rear) and you really do not want one snow plowing or to drive a BII on street ice with one (unless maybe you have a manual transmission).
I do agree a locker would be handy, but, I would only go selectable. The stock axles, imo, are just not up to lockers AND plowing.
The best route would be a selectable locker in a 8.8 or 9" out back and a L/S in the front Dana 28. Even just a limited slip in front would make a difference snow plowing. Of course, if you bury the right tire in a snow bank, a limited slip will be useless.

Tires and driving style do make a big difference. I ran a Lock Right in the front of my 90 BII for a while with 30" tall tires. It worked well. I like my stuff and don't abuse it much. I did break a drivers side axle at a place known for doing that. It dose reduce turning. With plowing I would upgrade to the front 35 if you haven't yet and see if a Tru Trac or Torsen gear biasing diff was available. Not sure a locker would be the way to go with extra load of the plow.

I believe the only locker or posi / limited slip differential available for the D28 or 35 TTB front are lock-rights. Not sure if you can put rear D35 parts in a TTB front axle, you may want to ask around and see if the parts are swappable. If so, you can do a D35 TTB swap and get either a posi / limited slip or go as far as getting an ARB air locker. As previously stated, yes, a locker will affect turning radius and behavior. You may also want to consider a limited slip or locker in the rear as well, if you don't already have a trac-lok or other limited slip in there. I would think you'd want as much "push" as you would "pull" in 4 low while plowing.
