No, don't worry about it. It's an open diferental.

Yah...What they said :-) Open diffs suck but it's the best we can get right now until GM gets off their rumps and fixes the problem with the H3. I don't know why they will put lockers in the H3T and not the H3 but time will tell on that option. At least we know we can swap the H3T chunk out and have lockers for our rigs for those with unlimited incomes.

I know I've asked this before in another thread, but I was always under the impression that when you switch to 4WD Locked mode, that all 4 wheels are locked into the same RPMs. So basically, it's just locking the front and rear differentials for 50/50 power distribution but the front differential is still considered open because of the amount of slippage it has?
And if you had a H3T and engaged the front and rear lockers and 4WD Locked, that means all 4 wheels will be turning exactly the same rpms all the time correct? that's why it's good, because lockers force both wheels to turn at the same time and give you equal left and ride side vehicle power?
Do I have this right (finally)?

And I apologize for the beating of the dead horse. I just want to make sure I know 100% what I'm talking about if anybody else asks.

You may have it?
The H3 has three differentials. One in the transfer case and one in each axle.
When the differential in he transfer case is locked, each drive shaft receives 50% of the power and will tun at the same speed irregardless of traction conditions.
If you have a locking rear differential, both rear tires will receive 50% of the power from the rear drive shaft and will tun at the same speed irregardless of traction.
When both differentials (central and rear) are locked you will have 25% of the engine power at each rear wheel and the other 50% at the front wheel with the least amount of traction (until the electronic traction control kicks in).
With all three differentials locked each wheel would get 25% of the power.
Clear as mud?
