Quadrasteer Suburban?!!

[Jabba]

Has anyone else seen the GMC commercial showing the GMC Yukon XL with the Quadrasteer 4 wheel steering option? Looks like a winner.

[Silvertwinkie]

I have and it looks real neat. I am unsure if it is offered in anything larger than 1/2 ton.

It is available in the 1500 HD which is effectively a 3/4 ton truck.

This would be my first choice in a new truck.

Not sure I agree. I admit they are somewhat similar, however 1500 is 1/2 ton, 2500 is 3/4 ton and 3500 is 1 ton. From my understanding, the rear ends can be different, the frame supports and some frame features are also different depending on 1500, 2500/3500. On the 1 ton, the axle hubs are even tougher. Toaster I am sure could chime in here though since I think he's the real Chevy truck expert......

I took a look at the 1500 and 2500 about 6 months ago. The 2500 (3/4 ton) appeared to be a tougher machine than the 1500 (1/2 ton) as such could be why they don't offer quadrasteer in the 3/4 ton cause the quadrasteer components might not be up to the task on the larger trucks that can get the larger engines and four wheel drive.

Silvertwinkie,
Key word here is HD. They are making a 1500 HD
Chevy /GMC is fooling with us on this one.
The 1500 HD is in fact a 3/4 ton model.
I believe it is the old 7000 GVW 3.73 gears light duty 3/4.
It does run 8 hole wheels.
Doesn't have the free floating rear axle nor the heavy 3/4 brake (rear discs)and suspension package.
I have only seen it in the 4 door model. Though it may come with the extended cab too.

I run the 2500 HD. It is 9200 GVW. Has 4 wheel discs. 4.10 rears
etc. etc.

Dad has got a '00 2500 (non HD). Great tow vehicle. Has 4 wheel disc and all the associated 2500 goodies.

I didn't know they made a 1500HD Yukon or Suburban...learn something new everyday. I thought they were only offered as pickups. Also didn't know the 1/2 tons had the 8 hole wheels.

Me personally, I love the 2500HD. I think it's the perfect balance between the 1 ton and the 1/2 ton. I also love that Allison transmission with the 8.1L and of course the 4.10 gears in the back.

But back to the post, we are talking 1/2 ton Suburbans/Yukons/Tahoes and you can't get any larger than a 5.3L engine and the GMC Yukon can get the 6.0L. Plus the 3/4 ton Yukon that has the quadrasteer does not seem to have four wheel drive as an option, and it's 1/2 ton counterpart doesn't seem to have four wheel drive if quadrasteer is installed either. Chevy now does offer a 3/4 ton quadrasteer, but I am uncertain if it also can get four wheel drive if it has the quadrasteer option.

At any rate once you go to the 3/4 ton, you start getting the meaty options like the Allision trans, big block or diesel which I haven't seen on any of the 1/2 tons SUVs or the 1/2 ton pickups either. The 1500HD can get the 6.0L engine though.

So to me the answer is sure you can get the 1500HD pickup or the 1500 SUVs, but the are not effectively a 3/4 ton truck exactly. As you pointed out, there are some features that the 3/4 ton has that the 1/2 ton HD models don't and/or can't have (unless you mod it yourself..which I have been know to do from time to time).

If you're talking about a Suburban the Quadrasteer option is only available on the 2500 (3/4 ton) with the 6.0 V8. It is teamed with several mandatory options making is a pricy (over $5000) option. To keep my wife happy I bought a Z71 Tahoe instead.

As for the pickups...all bets are off, I have no idea how it (Quadrasteer) is offered.

[Silvertwinkie]

My neighbor just did the same thing and got a Z71 Tahoe. Very nice.

I think the one thing we can all agree on is that all the GM truck lines are very good.

Just to dove tail off another thread, any of you that have the GM engines have any piston slap. Also on a thread around here I also read someone that said the 8.1L engine drinks 1-2 quarts of oil every 3500 miles. Anyone here have the 8.1L that can verify that claim?

Eric

[Pahaska]

I have never encountered piston slap. I did buy the truck with about 5000 miles on it, though, so I don't know what may have happened before.

[Silvertwinkie]

I just noticed that Chevy has 0% financing again or $1000 off the diesel/Allison transmisson combo.

Tempting on both fronts.

A question on the 2500HD. I have a 2002 and with the rear tires at the door sticker pressure, it has an unpleasently hard ride. This is with little load in the bed, no trailer. I remember in the past there being tables of tire pressure vs load. Are they still published?
Skip J

[Silvertwinkie]

I've never seen it. What we did was lower the pressure a bit on all 4 tires when not towing since we don't need the max tire load capacity. The trick is to find your sweet spot and not lower the pressure too much otherwise it's under inflated and that is a bad thing.

Even doing this makes it only slightly less harsh. The truck is built as a workhorse not a passenger car. It is far better than the previous gen pickups, but again, still far from a car like ride.

What engine do you have and have you exp any piston slap or oil consumption?

Eric

[Sav'h Steve]

I don't have a 3/4 ton but did read a while back that some had removed one leaf from the rear springs to make a less harsh ride.

If this works, that may be one answer as underinflated tires don't wear correctly.

Steve

[skipj]

I have the duramax diesel, no noticeable oil comsumption. Thanks everone for the feedback.

I usually run my tires at 55 lbs.
If I know I'm going to be carrying some real heavy stuff for a long distance I will inflate to max pressure.
But it is rare that I need that much carrying capacity.
I do have about 1500# of tools onboard at all times though.
For pulling an A/S you should never need to inflate to max as pressure is more a function of what you are carring not pulling.
I had to have my 02 2500 HD towed in to the dealer yesterday.
Came out to go to work and it wouldn't start. Lights, AC fan, dash lights all worked. But the starter wouldn't even click.
Wouldn't you know it, the warranty just ran out about 1700 miles ago.
GRRRRR

4th of July weekend we were camped near a family that towed their SOB in with a 1500HD Crew Cab. The guy wasn't to happy with his mileage, (6,0 L) claimed 8 MPG towing or not towing. I believe he said he had 3.73 gears. He did have CSK, I heard it one morning. It lasted about 5 seconds. I thought the motor was going to blow, it was so loud. First time I had ever heard the dreaded CSK. Much louder than I suspected it would be.

i've had really good performance with my 6 liter. and good mileage.

i wonder if you would have looked under that guys truck, you would have seen an orange oil filter with the name fram on it?

lots of chevys with csk have oil filters in them without drain back valves.
