I ordered an 07 Yukon 4wd a few weeks ago, and this post scared me - I didn't remember checking off the locking differential option. I looked, and it appears that the GMC 4wd's come packaged with the locking differential.

Here's the deal with the Tahoe. The locking differential is an option on all trim levels with the exception of the Z71. It is included with the Z71. If you get the 4WD option, it's a major blunder to omit the locking differential, also called limited slip differential. It's also one of those options that are way more expensive to add later on versus ordering it on the vehicle. Even if you never plan to go offroad, a locking differential is a lifesaver in the snow. The two manufacturers I've dealt with, Chrysler and Chevrolet have always sold it as an option on their standard trim lines.

No premium suggestion (or any other sticker) on my XL gas door/cap. Manual states 87 unleaded for any engine other than base 5.3, which can use blended fuel.

There are no damages here. The dealership offered to return your money for the mistake. You're out nothing.
Two choices.....take the vehicle at the higher price, or take the refund and look elsewhere.
Pretty simple. Until you sign the finance contract and take possession (drive it off the dealer's lot), there is nothing that you're out.

My 2007 Tahoe came with Locking Rear Differential as part of the LTZ equipment group package. And by the way, I just went over 23,000 miles and I'm still very happy with the car. ZERO problems or complaints.. Got to try the Auto & 4WD modes in the snow last week. Car was great..

Curiously enough it seems to me that when you compare spec for spec a well optioned Yukon with the locking differential is significantly ($2000) less than the same level of options in a Tahoe. The only difference seems to be that the Yukon even when loaded up doesn't have as many power seat adjustments (6?) as a loaded Tahoe (12). (They must be saving this for the Denali.) I do see that the Yukon offers a an external oil cooler as an option. I would think this would be a must-have option for Yukon buyers and a must-have dealer installed option on Tahoe's (just buy it at the GM dealer).
Speaking of oil coolers, I'd really like to see Tahoe have more factory towing/engine/transmission options. These upgrades are cheaper in the long run. We've gotten 20 years of hard use out of an F150 because we specc'd it with a 351 engine, not the 302, and not so incidentally, this larger engine came with the far superior C6 tranny, a tranny cooler, etc.
Additonally, and this is from memory, it seems that the $4500 bump from the highest level of the LT option package to the LTZ is a very costly step indeed. Unless you really need a third row seat, Autoride suspension, locking differential, power lift gate or heated windshield washers. These options are all available separately and it might make a lot of sense to just pick and choose. (Living in the Northeast I would take the heated windshield washer fluid and the locking differential and pocket the $4000 savings.)
Finally, I couldn't find any space on the GM "build this vehicle" Tahoe section for the Z71 option. Did I miss it?

Good info and points. I hesitated to chime in about the locking differential and the LTZ package, because I wasn't sure if it was included as part of the LTZ package on the Tahoe or not. It was part of the LTZ package on my Avalanche, along with most of the same things you've listed for the Tahoe's package (minus power lift gate, third row seat, heated second row seats??, etc.).
hardin_thicke- one minor correction. You've said that the locking differential is "also called limited slip differential". This is definitely not true. In our GM vehicles, which are equipped with the G80, this is a true "locker", that locks both wheels together if more than 100 rpm difference exists between the two rear wheels. There've been a lot of posts comparing the "limited slip" differentials available in other bands to the lockers in GM vehicles. With the locker torque is split evenly to both rear wheels when it locks, as they are physically locked together (like a solid axle). Limited slip differentials only transfer some of the torque to the wheel that's not slipping (and usually a very limited amount). There've been a few demonstrations on some truck television programs of why the locker we have is better than the limited slip for most normal "truck" use.
Limited slips do have advantages for racing-style and performance vehicle use though..

You're right Jerry on the locking vs limited slip differential. Thanks for the correction. My present ride, a 2500 Turbodiesel Ram has a limited slip diff, and although it's very effective, it took time, and a lot of patience to get it to work just right, adding the "slip fluid" and trying it, then add a little more, and trying it. And when you change out the gear oil, you have to do this all over again.

FYI the oil cooler is only available as a factory option if you order the 4:10 gears, if you do not select the 410's when building the truck, it is not offered as an option. I just purchased the factory cooler from Chevy for $80, as I ordered my LTZ with 3:73's - Hope that helps, george
