[Spridgets] Diffs again, if I may

[David Riker]

I won't talk about what I don't know, but about what I do know.  Chevrolet 
Trucks use a differential made by Eaton called a G80 Locker.  They have a 
demonstration trailer with rollers on one side to simulate loss of traction 
on that side.  They then drive Toyotas, Fords, Dodges, and Nissans up the 
trailer.  As soon as the trucks hit the rollers, they stop moving and the 
wheel on the side of the rollers spins uncontrollably.  All of those trucks 
claim to have a "limited slip differential".  Only the Chevrolet with the 
Eaton locker continue to climb the trailer.  So from what I've seen, unless 
it is actually a "locking differential"  all the torque sensing BS is just 
that..... BS.  As soon as there is 0 traction, ie a broken axle, a wheel off 
the ground, etc, nothing is going to happen.  The Eaton system uses 
centrifugal force of the spinning wheel to lock the two axles together when 
slip is encountered.  All the rest are smoke and mirrors.
