BTMing pretty much overides it , i think

we need f5 to the rescue

In soft dirt, sand etc, it is best to allow the traction controll to do its thing, by allowing the wheels to spin until traction is transferred to the wheels that have it.

In situations where "sudden" traction can cause damage to moving parts, (front axels:-), using BTM and NOT allowing the wheels to spin, thereby not giving the traction control an opportunity to engage is best.

Like that:D

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:rolleyes:

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. :rolleyes: 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:D

I really don't know about the Manual, this conversation does not apply to Manual.

So turning it off dissables the ABS controll traction control on all wheels correct?

I believe there are three systems at least...

Electronic Traction Control
ABS (Automatic Braking System)
Stabilitrak


I haven't tried it in low range locked up yet.

If you have a stabilitrak button, it may be a dummy??? Put the truck in 4lo lock 1st gear, and see if you get the warning on the DIC.

I guess the weak link is the Al diff housing with all the torque from the 4:1 t-case.

According to my sources at GM, the problem is twofold. It is the aluminum housing and a ring gear that may not have been hardened properly. They are looking for a fix to the housing issue, and they are increasing the (?fancy word for) tensil strength of the ring gear.
