I just regeared, and while I was at it put in a LockRight in my front diff ('89 Toy IFS).
Note - thsi is my 1st experience w/ a front-locked vehicle and/or auto-lockers.
After the first drive, I'm a bit surprised at the way it behaves.
W/ hubs (manual) locked but in 2wd, street manners are fine - cornered pretty normal, although I do have a consistent Click-Click-Click about 6 times per tire revolution during sharp (90 deg) corners... but it's not very loud.

W/ 4wd engaged, though - Holy Hell, steering is out of the question. It drives like the front is just welded - serious scrubbing doing corners, pushes me straight. What really surprised me was the amount of torque steer - applying or letting off the gas would push it to the side, like a stuck brake caliper might.
This is all on pavement, about a 1 mile jaunt around local road.
I guess what seemed odd was that w/ 4wd engaged, so power is ocming from the DS, the unit never seemed to disengage so the wheels could turn. Isn't it supposed to? I thought the point was the stay engaged when straight, then w/ turned drop out/open up, then re-lock again. In the first condition above, both shafts are still turning due to the locked hubs - it's fine w/ that.

How much of this is normal? Never driven a front-locked truck or auto-locker.
 
Every bit of what you described is normal. When ever you are under accel the front drive shaft is applying pressure to the king pin which in turns applies pressure to the lockright and wont let it unload.
 
Oh yea i forgot to tell you about it unloading when it sounds like the front end has come out of it dont worry it is normal.

Hm. Great.
I'm beginning to wonder how much fun it will be when i tsnows here :wheel: but I have a car for DD anyway.

The Click-Click-Click around corners - is that normal too? I can't remember how many teeth were in the unit.

Actually - so - not applying gas should let it unload? I have an auto tranny so popping into neutral isn't so easy to just do on the fly.

Of ocurse this is 90% irrelevant since on te hroad I'll have the hubs unlocked anyway
 
Are you driving it on the street like that? If so that is your problem. The Lock Right is a simple and straight forward design. If you stack it together like it is inside the carrier you will note the slightly oblong hole where the center pin goes through. When you apply torque, the center pin pushes against this forcing it to try to spread apart making it lock. In 2wd with the hubs locked there is no torque on the drive-line so that is where you get the clicking from. In other words The behavior is perfectly normal for it.

It wont be bad in the snow because the tires will be able to slide unlike on pavement.
 
For God's sake, leave the hubs unlocked and leave it out of 4wd on dry pavement.

Everythign else is normal for the way ti is acting, but you shouldn't be driving it that way.

As for the snow, you can lock one hub and you will be fine...
 
Yes the clicking is normal. Uglyjeepoffroad is right unlock your hubs or you will break a axle!

Was wondering where he got the idea that it was acceptable to low lock on the asphalt :shaking:

Ok, I get it.
I know it's not normal to do that, intended, or even a good idea.
But it's always handled perfectly fine on paement w/ the hubs locked, just a little jerky in tight turns.
I have no intention of doing that on a regular basis.
My misconception was simply that it would still unload w/ the accelerator applied IF it was turning, saving the axles. Now I know otherwise.
