i never had a detroit, so i'm no expert. Looking at the pics would lead me to believe that is always engaged and it will skip or click or step over when there is a difference in travel between left and right wheel. So i went and typed in "detroit locker operation" in google
came across an explanation on a site:
"The Detroit Locker is an automatic locking differential designed to lock both wheels of the axle together automatically with power input, when forward or reverse torque is applied, so that both wheels are providing 100% power to the ground. This action creates essentially a "spool" that solidly connects the axle shafts together. When torque is not being applied, the Detroit Locker is allowed to unlock, permitting a differentiation variance in wheel speed while negotiating turns. The later Soft-Locker design has a stronger case as well as a dampening mechanism to reduce banging and clunking characteristic to the earlier Detroit Locker."
so that is pretty much the opposite of what i gathered looking at the pics
now if someone can explain how it actually operates in plain english would be of great benefit as since i don't see clutch disks or spider gears i can't get my head around it - is one wheel disengaged at all times or once you hit the gas will engage and make it a spool until you lift a bit and it will skip - if that's the case then all of you are correct and actually explaining the different stages of the detroit operation. Again, if someone can explain how it works that would be greatly appreciated.
