Kinda.

As I posted above, because it has to allow for a differential in speed between wheels, it splits TORQUE. When one wheel spins up, it no longer transmits that torque to the ground, therefore the other wheel is limited in the same regard.

A locker takes away the ability of a diff to allow a difference in speed. For example, say you have an e-locker engaged, with one wheel on ice, the other wheel on asphalt. The wheel on asphalt will be pushing much, much harder than the wheel on ice, because it's gripping. Meaning that side of the axle will be receiving WAY more torque than the side that is on ice, as the wheel will simply slide and not transmit the power to the ground.

Simply put, a locker allows more torque to go to one wheel, whereas an open diff does not, limiting the whole axle to the wheel with the least grip.

Related questions here. The words "AUTO" and "LOCK" are worn off my hubs. I can only see the dots to line them up. Are the hubs the same on both sides? Auto to the left and Lock to the right or vice versa? Or is it Auto the front and Lock to the rear or vice versa?

I don't remember which way is which but both sides work the same way not to the front or rear.

They can be switched from side to side (identical). Clockwise is lock on all hubs. Think of thightening a bolt. Righty tighty, lefty loosey.

Thanx for clarifying... an open diff or LSD is 'essentially' primarily driving one wheel ( the wrong one) in regards to what is needed in a less than optimal traction situation.

Right, LSD (limited slip differential) will drive both because they lock together through clutches, but an open one just pushes both until one gives away. This is due to the spider gears in the diff. They revolve until they have enough resistance to rotate and then they revolve and rotate at the same time. An ingenious invention that has been the same for about 80 years. Probably 90% of all diffs are open.
