That's what I'd wondered about. For one example... Sharp turn at the crest of a hill... can't let up TOO much, because your rear is still climbing, but don't want it pushing too much since it's locked. My brother (elocker) generally unlocks when it isn't NEEDED... including while finishing a climb like that.
What about a sharp turn on really sloppy/slick stuff... either mud or lots of wet leaves on soft dirt. You aren't in danger of getting stuck or not moving, but obviously need a LITTLE gas to get moving... is that enough to lock it, have it push, and have a wider turning radius?
Our trucks don't go between 2wd and 4wd all that quickly, so constantly switching isn't really a GREAT option.
Lots of trails are really geared towards Jeep turning radius... ours is close, but 2 point turn gets annoying, and losing momentum isn't an option at times.
<I still think benefits out way cons, and will probably get one (added benefit of not blowing spider gears)... but these are my doubts. Maybe there will be a slight learning curve, then it's all good from there?>
I run 4 low all the time since I am six speed. The trails can pretty tight here in East Pennsylvania (check out the tree carnage in my build). With the Lokka the steering is only a tiny bit harder than normal. It doesn't feel like a switchable locker.
There is one particularly tight turn on a trail that I frequent. If you don't hit right, you will bash your front bumper into the tree or have back up. There has been no difference with or without the locker.
Locker newb here... How harsh are lokkas on average when engaging? Of course if your mashing the throttle any locking device could slam, but when being easy or moderate can they still be harsh or firm?
I used to have a 2005 tahoe with the auto 4wd mode. Worst thing ever. During winter driving it would try to engage at any speed if it sensed rear tire slippage and would slam the crap out of the front drive line and transfer case almost every time because it would engage so quickly you had no time to let off. I never used it because of this. And because of this I've always feared front auto lockers. For anyone not familiar with the GM auto mode it was basically a hydraulic clutch pack inside the transfer case that would lock the forward output shaft when needed.
In 4wd and under power, it is always on. There is no engaging. The only thing that happens is it disengages the faster turning wheel when in a sharp turn. This action is smooth as butter.
Trails out here are tight with lots of trees. You need to be able to turn sharp and not be locked in the front bulldozing foward smashing into trees. Thus selectable is the way to go.
More so, I'd never run a Lokka in a a DD that's driven on icy/snowy roads. When going around a curve on icy/snowy roads I'm not going to risk this this locking and unlocking and changing the traction and ability to steer forcing the tires to slide because the turning radius is being forced to be the same for both front wheels.
If I can't afford a SAFE to use, selectable front locker, then I can't afford a front locker. I'm not risking injury to my family on the highway and or rolling/smashing up my rig just to save a few hundred off an ARB.
Here's an example of what can happen when you are locked in the front when you shouldn't be. Pay attention the the front tires. With an open diff, the X wouldn't have been forced sharply left in the front.
This is the obvious voice of reason.
Where I live they use so much salt that the only time I use 4wd is when I want to go out and play or when I come to a stop light to get rolling again.
On the trails, it feels great to me. You do have to know what the front locker is capable of and plan your risk accordingly. That video looks like a few things went wrong including too much skinny pedal.
This might be a repeat but my personal reason for going lokka was that after I shredded my spider gears, it cost me $300 to get back on the trails and fix the part the broke. Going arb would have locked me (no pun intended) into 3.69 gears and r180. I am still not sure I am staying lokka...
