Was at the chevy dealer yesterday, looking for a 4WD truck with a rear locker. They had some but one of them had a limited slip ( 2013 low miles, 1/2 T fleet model). 3 salesmen did not have the slightest idea even what a differential did period. Had to wait (hours?) for the --->one guy<--- who knew more about drivetrains than anybody in the dealership.
So I asked him "what kind of 'limited slip' is in this pickup?". He said its a viscous coupling. That was the first I'd heard of that in a differecntial. I've seen those in a primary drivetrain but never after the ring and pinion after the speed goes down and the torque goes up (by a factor of 3 or 4). Well anyway he went on to explain that if there is more than 100RPM difference between the rotational speeds of the left and right wheel, it locks up. Incidentally, that means the driveshaft is spinning or 4 times faster.
hhhhhhh o-o-o-o kayyyyy?. That sounds like "already stuck" to me. 10 RPM difference sounds stuck to me. I did not get the impression this guy knew enough to be consulted about drivetrains so I'm asking here.
Does anybody know about this Chevy "limited slip"? What does Ford use for their "limited slip"? (not referring to "electronic lock" option, but "limited slip")
