only traction control. Correct.

The Stabilitrac conversation does not apply to those owners with a Manual trans.

So HummBebe I should turn of the traction control (the vehicle with squigly lines) on rough rocky trails and let the front wheels spin?? You cannot turn off traction control. And no....

Read my response again....only in soft soil and sand

To disengage Stabilitrac (not traction control)you put the truck in neutral, press the button that says 4lo with the picture of the little lock next to it. Put the truck in 1st gear, the Stabilitrak system off message will show on the DIC in front of your steering wheel.

I thought the idea was the brakes slowed the wheel that was spinning and transferred the power to the one not spining?

Uh no, you missed it again....traction control works only when the wheels are spinning, if you apply the brakes it prevents traction control from engaging. Hence, BTM prevents traction control from engaging.

Typically, you would be in 4 hi or 4 hi lock when you are in soft soils and sand, which allows traction control to engage.

Do you think the traction control casued the shock loads that breaks the ring gear or the shock from spinning wheels sudennly grabbing solid ground?? NO, I was not spinning the front wheels when my diff broke. It was the torque that caused the diffhousing to flex, forcing the pinion gear into the ring gear and grinding off 8 teeth.

Still think the diff housing flexes?? I'm sure that it does, it has been confirmed by the GM engineers that this in fact is the case.

I'll be carefull with my lead foot for awhile. Ask people who wheel with me, I'm usually the most cautious of the group.

Why didn't GM give us a real front locker with an on and off switch with the Adventure Package? AMSTAR is working on it as we type, so am I

I hope this helps.
