Front axle locker drivability with only one hub...

I see that jeep people do that for better turning radius with no issues, but how will be on our trucks? I don't use my truck for DD and it never snows here. So two wheel drive is all I need for driving around. I do like to go to sand or trails and locker would be nice, but in case if I need to turn sharp or if I'm in not too crazy situation, will it be driving ok with 3 wheel drive? <br />
Selectable lockers are not in my budget, so only choice is lock-rite or equal, but if it totally suck driving on trails with front fully locked or with just one hub, then trac-lok posi or equal would be my only options.

Front axle locker drivability with only one hub engaged?

I spent a long time wondering the same question. I decided that it was not worth it. I ended up getting a Dana Power-lok. I arranged the clutches to be very aggressive, they grab like crazy. I really like the set up, the truck goes most anywhere I care to point it.

Update: I finally got it all wrapped up little while ago. Detroit locker in front with Ford dana 60 knuckles, free spin hubs and brakes. Left vacuum CAD original for now. Finally went out to do some wheeling on the trails.
I love it! Detroit in front actually letting me steer pretty good. On the trail I had no problems going around the corners that wasn't too sharp, if it was too sharp, then I would back up and go back and forth a few times to get me where I want to go. But on the trail and mud pits this thing was unstoppable!
I tried driving with one hub unlocked, not bad at all. It does want to steer one way or the other, depending on if I was accelerating or engine braking, but easily controllable.
Granted all my drivability testing was on gravel road up to 30 MPH and I probably wouldn't want to drive with one hub engaged much faster than that.
I definitely wouldn't put Detroit in my DD, but this is my toy and I tow my toyhauler with it and we like to camp on the sand, so it will be perfect for that! Dragging 10000lb trailer through the sand gets pretty challenging some times.
I'm really pleased. I only spent $200 for used locker. Selectable locker would be much better, but for me its worth jumping in and out of the truck to lock/unlock hubs to save a $900. It will keep me in shape lol.

I wouldn't risk it driving on public streets with one hub on. It is safer having them both engaged. It does steer ok at slower speeds, but the faster you go through the curves, the more you feel the drag. Also its really hard on steering components.
If you only use 4x4 on construction sites/farm- go for it
Street driving grocery getter - I would get selectable locker.
Also I was reading about CAD cable, and people having a hard time engaging/disengaging locked axles. I will try to fab up vacuum solenoid with the switch instead.

before I got the posilock cable I used a brass fuel tank selector from a old farm truck to control vac to the cad. the only trouble I had was in winter moisture would cause the cad to freeze using vac, that's the reason I went to the cable.

Good suggestion! We hardly see below freezing here, so that should work good. Thanks

one day we might be 30 the next day -5 that causes trouble in anything vac controlled.

I know it aint cheap (trust me) but an air locker in the front is the way to go. Flip a switch and it's locked. Ditch the cad all together and toss in a set of manual hubs and you have one reliable and versatile setup.
