Absolutely! As another poster mentioned, it's not really a limited slip
differential at all. I tend to avoid electronic traction control on
4x4's. My off-road use often involves airing down tires, which usually
confuses the heck out of them. These devices usually use the brakes to
grab the spinning wheel, mechanically forcing the torque to the wheel
with more traction, which the differential now thinks is the wheel with
LESS traction. Another poster mentioned "hydraulic pressure", that's
brakes. In a vehicle with ABS, the wheel speed sensor is already there,
so adding computerized traction control is cheap and easy. Even the
cheesy Chevy Cavalier had a version of this.


Here's some background on how a differential works, which will make the
computerized brake application make sense:

Limited slip and locking differentials are frequently confused, and
Toyota does offer an electric locker, hence my request for clarification.

A real LSD works ALL the time and won't be damaged by high-traction
surfaces. A locker mechanically locks both axle halves together,
defeating the operation of the differential altogether. This can have
an effect so extreme as to push you straight ahead with the wheels
turned on low traction surfaces.

The other "opinion" that questioned my referring you to the manual even
confused the LSD button with the 4WD selector and air suspension. <G>

FWIW, running the truck in 4WD for a few miles on a regular basis is
usually a good idea. Do this on rainy days, and not in areas where
tight turns are required, like parking lots. This actuates all the
parts, spins the shafts, and distributes lubricants.

Good luck with your brush guard...
