Pretty quick damage after a few min on the trail. Found it entertaining. A good video on what not to do lol?

saw that video, lookd like he did the dreaded "accelerated bounce with front wheels turned" maneuver.
to their credit, they admitted not knowing enough to anticipate.

I found this comment interesting:
"Inadvertently, you created a video showing the 100 series weakness. The ATRAC system is slow in this LC, unlike new 4Runners. When the LC began going backwards with the left wheel in the air, Tommy added power and spun that wheel. When the full weight of the LC hit the rock while spinning, broken differential was the result. ATRAC hadn’t kicked in yet. Lesson: if you’re going to rock crawl a 100 series, be aware of the risk, or put lockers front and rear. There are multiple videos online of similar incidents."
So my LC100 is Euro spec 2001 without ATRAC and with rear locker. Would I have had the same problem in this same situation too?

He woulda been fine if he stayed on the throttle and didn’t roll back.
But without the rear locker engaged it would have?
I'm just mostly curious, trying to stay educated and avoid similar situations. There's no rock crawling where I live, all we have is mud, snow and some sand.
@RockDriver Difficult to say but unlocked (F&R) and no ATRAC, if you two foot it (one foot on gas and one foot on brake) and ease into it, it would also not roll back like that. But you would also not make it up that without changing your line.
Very entertaining indeed. Lessons were learned from this video.
FWIW they also immediately grenaded the front diff on their new Tacoma

They seem to love taking their 100% bone stock 4x4's with passenger car tires off-roading. A set of a/t's wouldn't make for as good entertainment I guess.
It looked like throttle was being applied when it rolled back (front driver's tire appeared to be spinning). Almost like it was an ATRAC hiccup from it being in a diagonal spin condition. I've personally never had ATRAC do that on similar obstacles - usually it just stops making forward progress and makes a racket as the ABS pump clamps down on things until it eventually moves forward - but don't recall it ever rolling backwards.
There was some movement in the wheels, but totally possible it was a light "tap" as opposed to actually stopping momentum (which is what I normally do).
Regardless I'm glad I sprung for lockers and got rid of the even weaker 8" diff on my rig. Prior to diff upgrades, there were several obstacles I did not attempt due to a fear of blowing up my R&P.
You are right, brakes were on, although the PS rear tires was still spinning forward. So he had one foot on the accelerator, foot on the brake (but not hard enough to stop the rig from actually moving), then a "pop" when it finally catches. Definitely interesting driving technique

Left foot braking is great for technical terrain but doesn't jive with ATRAC. If he was in a 98-99 without ATRAC, he should've had the brake on the entire time but modulated speed by releasing the brake and holding throttle.
So, the moral is: no 2 foot driving with an ATRAC 100? Just dont wanna do this to my truck.
