some footage of the driving a few weeks ago....
Exactly at 10minutes in the clip below, you can see my PS front hitting the rock causing a broken birf. (More on that in my thread...)
Went to a total stop out there, but did not notice the lack of traction (and noice) until later, so i mudded on. :steer:
Wonder if this would have been avoided without a autolocker front...

Of course, this could have been avoided going slower, or going around it.
I have done this exact spot before, never noticed the rock before, just hit it dead on this time.

 
I don't think you can totally blame the locker for that. Unless the tires kicked all the way over while you mashed the pedal down. But it doesn't look like you did that.

If you are running stock birfs, 35's are really hard on them and how many miles are on the birfs? I just got back from Rubicon and I did blow up a birf but it was caused by an unlocked hub on the opposite side and coming down off a rock under power. (I have air lockers by the way). Fortunately I did hear and feel the grinding coming from my front axle.

My two cents.

Of course it could have been avoided; keep your truck parked in the garage or at a minimum, keep it out of four wheel drive and on paved roads.


:wrench:

yeahyeah, Poser, i get it! But i intend not to... ;)

Theese are "better than stock" TG birfs. Less than a year old.


Would i have broken it if i were open diffed front? Was revving in 2nd...
 
I don't want to open the bashing but you get what you paid for when you buy "made in china"
 
unlucky i say,
been in mud like that with rocks like that and who knows what in it,

hmmmm,

wheen spin then sudden stop of wheel spin from a gain in traction broke it.
 
Says who?

Trail Gear...:rolleyes: they are way cheap, and i am not heartbroken of the birf going south, i'm just glad i have another one, just as cheap, just as "better than stock" or whatever.
Longs would be great, but i keep changing them until i can afford putting the manual locker up front with longs or similar (long spline inner needed) , and move the autolocker rear again.

I know. :) They've held up against some rough stuff, i dont know if they actually are any better than stock, i dont even care really as long as i pay 1/5 the price on this crap over the stock one.

Nice clip, the only trouble is that freakin music, what are we in a disco while we 4wd????

Hahah, not me making the video, i'm just in it. Its not a music video either, i just push MUTE. Sure would be better to hear the 2H.

Correcta mundo.
 
Simple physics...you placed to much rotational torque that exceeded the design limits of the birf. We had torg sensors on our engine drive shafts that is the torque was reaching design limits, it would blink a master caution light in the cockpit and the pilots would reduce engine input.
 
I know, Rusty.
I think the reason I asked this question years ago, was to debate wether the shockloads of an autolocker is less kind on any birf type, witch my personal experience over and over again seemed to prove.
The more constant load of an acuated locked will keep the rotational force at a more constan level, even with different traction.
To take that clip above as an example, the locker engaged when both tires went from spinning, to when the right tire found solid traction.
If I had a locked front at the moment, I think the outcome would be different, as the one side who suddenly got traction, wouldn't reduce speed, just keep spinning at the same pace.
If then the axle had enough rotational strength, it could have survived.

Anyway, just a theory from my side.
