That will not necessarly prove it is in there...
Find level ground...side of the road...drive 10 mph with the right tires in the dirt...left tires on the pavement...punch it.
If you only spin the rear tire in the dirt...your empty.
The GT requires both tires to be spinning to fully "lock" so to speak.
If you have a little momentum before the loads are unequal to each rear tire, the GT will do a GREAT job of 50/50 split of torque.
Anyways...
XLR8R,
I didn't have my camera ready, and the dealer already made the wrong right...
but I could get a signed affidavitt notorized for you? Or is it for DC?
Lost here? There was ZERO arguement from the dealer on what to do.

Glad your problem was resolved; I was hoping those of you that reported this factory omission would help anyone else that faces the same problem... usually when you tell a tech, parts mgr, salesman - or even Joe Six-pack - something like this (even with a straight face!), they just look at you like
Perhaps someone else is able/willing to help...

No need for an attitude.

Funny thread this was…..
Some good information and some not so good information.
IMO there are four categories that diff fall into.
Open
Limited Slips
Lockers
Hybrids
They all have there good and bad.
Open – Not sure that there is much to rave about here. Reduced tire wear, but you can achieve that with a hybrids also. In equal traction conditions, each wheel supplies 50% of the available torque to the ground (100% totaled). The wheel that looses traction will receive all available torque from the opposite wheel with traction, until that wheel is receiving 100% of the available torque. The only way to change this path of least resistance is to attempt to slow the spinning wheel through the use of brakes, thereby forcing torque back to the wheel with traction. Does this work? In some situations this can work to a limited degree and will never come close to equaling other traction differentials.
Limited slips – These come with many names but the premises is still the same in that they attempt to limit the loss of torque supplied to the wheel WITH traction through various friction devices. These friction devices can be clutch packs, cones and gears. Most quality LSD’s attempt to keep at least 30% to 40% of the available torque going to the wheel with traction. These also have some limitations as to there ability to operate properly in that the complete loss of traction by one wheel combined with high wheel speeds can impede the clutch packs ability to transfer torque. This is not a problem that I see with the gear type LSD’s. LSD’s can also benefit from the application of brakes in certain conditions.
Lockers – Using an automatic mechanical means to supply 100% of the available torque to the wheel with traction. Only downside are broken axles and increased tire wear. The use of brakes with these types is mute.
Hybrids – A combination of different types of mechanical lockers that are activated by the user. Ideally, the best of drivability and off road performance.
I hope this wasn’t argumentative, but rather it be informative to those that are interested.

Just a small point. With open diffs the wheels always get equal torque but the speed is different. Unlike a locked diff where the torque is different but the speed is the same.
