GX550 Premium, only front left wheel and back right wheel spins (1 Viewer)

[sunnyday]

Hi, noob question here.

Today I got stuck in sand with gx550 premium.

I enabled L4, then pressed the button with wheel lock.
But only two wheels spun: front left wheel and back right wheel.

I wanted all 4 wheel to spin.

What did I do wrong?

Likely nothing, that’s how open differentials work - torque “chooses” the path of the least resistance so it goes to wheels with less traction. Non-overtrail models only come with a central locking diff - when engaged power is split 50-50 between front and rear axles, not between left and right wheels on either axle.

That said, even non-overtrail GXs come with Toyota A-TRAC system which applies breaks to wheels with less traction, when it senses slip, in order to send power to the wheels with more traction. That system supposedly engages when the track is put in 4Lo, and, from what I heard (never actually tried myself), is pretty efficient - locking diffs should not be needed unless in very hard, rock crawling conditions.

Thanks! This clears up my confusion.

If I wanted my wheels to actually spin on the wheel that touches the sand, do I turn on the wheel lock? What about L4?
