I will repeat here, what I have said elsewhere. I am really disappointed in GM
for putting this ...
about the whole approach to fuel effeciency.
   
GM had (perhaps still has) an opportunity to provide far and away class leading
fuel effeciency and instead they decide to provide more power through a larger
V8. AS IF the 5.3 of today WASN'T large enough! At last report the new and
improved Tahoe/Yukon is slated to receive a 6.0 liter motor! So GM has decided
to take the effeciency gains from their new Displacement On Demand technology
and drop in more power - because we just didn't have enough before! Yes, this
was the wisdom that came out of GM headquarters in this - the time of $3.50 (and
climbing) a gallon regular unleaded. Let me put this another way. Instead of
going for the gold - in fuel effeciency - GM settles for a pitiful 2.1 mpg
improvement in fuel economy. This assumes the optomistic prediction that Edmunds
quotes of a full 15% effeciency gain and 14 mpg city driving.
   
No wonder GM and the other domestic auto makers are in such trouble.
   
Anybody else still wonder why Toyota is posting such huge sales increases?

  
I'm afraid you need to do your homework. GM leads the class in standard hp yes, but they
also lead the class in fuel efficiency. That's right, the gmt900 SUV's achieve
better mpg than Ford, Dodge, Nissan, or your beloved Toyota. You sit here and
criticize the fact that GM isn't doing enough to increase the fuel efficiency of
their large trucks and Suv's, and you say that Toyota is better, and no wonder
they are doing better?! First of all, GM far outsells Toyota in large SUV and
truck sales,secndly, Toyota offers a much smaller engine that gets worse mpg,
and third, lets not forget that Toyota is now going t o offer a 5.7 L engine in
their redesigned Tundra and presumably the Sequoia when it's redesigned, and
they have made no attempt to offer such fuel saving technology as DOD. Add to
that the fact that GM will have hybrid versions of these vehicles in a matter of
months, and these engines can be run on ethanol( a clean burning, cheaper,
American made fuel), and it's very clear that GM's large SUV's and trucks are
superior in fuel efficiency and power to Toyota's large SUV's and trucks.

I saw the GM mat at my local dealer's parts department.

Dear Tourguide,
As I read of your diaappointment, I was compelled to reply.Even though your statemnts were made in Sept. 05, long before the actual release of the various GMT900 SUVs, I felt a few more comments to your statements were in order. As the previous owner of 2 V8 Tundra 4 x 4s and now the own of a 2007 GMC Yukon, I am totally impressed with the GM fuel economy vs the Tundra fuel economy. Over 6 years of Tundra ownership, I averaged +/- 14.5mpg in all conditions.Currently, I am averaging 16.1 MPG with the 5.3 Yukon after 3000 miles. I am averaging 23.4 with my GM 5.7L Corvette. I never averaged that high with my V6 Camry! Yes, reliability and resale may be other topics for debate, but time will tell. GM has improved, Toyota is flat.

Then again, a Camry probably doesn't weigh less than--and probably also isn't as aerodynamic as--the Corvette.

Not to jump onto this one late.... but isn't the Tahoe/Yukon ultimately slated to have a 4.8 V8 by year's end to replace the 5.3? Only the Z71 and Denali get the bigger engine... unless I missed the latest memo, which is entirely possible.

No, the 5.3 will not be replaced by the 4.8.
 
The 4.8 is the "econo" engine, available in 2wd LS versions.
 
The Denali will remain with the 6.2, and the Suburban 2500 will have the 6.0.

I do not think the RKE module and the Nav DVD are related items. When the DVD running, you should hear spinning sound of the disc in the DVD player. Whereas the RKE cycling should have some sort of solenoid clicking on/off.
 
Next time, you exit the vehicle, have your windows down and lock up your truck. Then listen to the noise from the outside after 5-10 minutes. GM vehicles used to have option that let you listen to radio even with ignition key is out as long as you still in the vehicle. Now if you are out of the vehicle, everything should shut down gradually after some minutes to save battery. If the DVD keeps on spinning all the time, the longevity of the battery will be affected.

Ok Compare the Camry to the Impala SS. 5.3 engine with 28mpg. 303hp and 323ft-lbs of torque.
 
Back to the Tahoe 15/21mpg 320hp 340ft-lbs
 
Other 4x4 with standard engines
 
Toyota Sequoia 15/17mpg 273hp 314 ft-lbs
Nissan Armada 13/18mpg 305hp 385 ft-lbs
Ford Expedition 14/18mpg 300hp 365 ft-lbs
  
 
The Sequoia's tow rating is 2000lbs lighter than all the others. I'd give up the 30ish ft-lbs of torque for the extra 3 or 4 mpg.
If you need your exra HP and torque well the Denali should do it then...13/19mpg and 380hp 417 ft-lbs. Highway mpg still better than the competition.

GMC Yukon XL Front Differential Problem by blackdmd
Jun 14, 2006 (9:39 am)
Reply
Has anyone experienced a situation where their 2003 (or other similar year/mileage) Yukon had the front differential need to be replaced, along with the front wheel bearings at 85,000 mi? This just recently took us by surprise after buying it used with no known defects and a clean maintenance record (corporate fleet). The dealer tells us that we need to replace the diff. and at least one wheel bearing....$2100!.....This isn't an AWD Yukon, just 4 WD on demand. Any thoughts? Any cheaper solutions? Any warranty? Would love to hear some ideas and comments.
