The Tundra stopped much quicker from 70 mph, taking just 201 feet, 18 fewer than the GMC. Neither set the skidpad on fire, with the Toyota taking the 300-foot circle at 0.72 g, the Sierra at 0.68 g.

We’re happy to report that ... the Tundra exhibits a near carlike ride on the highway and spirited handling in the twisties. Sure, the ride was firm, but not harsh like the Silverado.

On my Tundra I still do this, however in heeding your many warnings I only do it for straight line driving and only for a few hundred feet at a time.
In your honest opinion - Cliffy, et. al., is this beneficial or not needed or dangerous?
Jeff
Also - I don't think (and you all can correct me if I'm wrong) this is limited to just Toyota 4WD, but any 4WD (as opposed to AWD or command trac or other "smart" drive systems).
Could somebody clarify just what harm results from driving on dry pavement in 4WD?
Jeff
Most standard 4wd systems only have a transfer case
Linking both the front and rear axles in a 1:1 ratio.
Now the problems come in when you need to make a
turn. The track of the front wheels is different
than the rear wheels causing "driveline windup"
This windup causes a stress on the u joints
and related components of the transfer case trans
and axles. On dry pavement their is little to no
slippage and can seriously break parts.
Compared to the Jeep Grand Cherokee that has an
AWD function. The Jeep uses a "Viscous clutch"
to allow a certain degree of slippage between the
front and rear axles. Other systems will use the equivalent of a Differential between the front and
rear axles.

go out 4x and have fun. Kind of like an apple a
day.
F1: will a 3 inch pipe fit all the way down the line on A Tundra?? What I got when I went to have what you are getting done I was told that they could put it on, but there were problems. They have to remove the spare, The underside mounts will get burnt after time, and then there is warranty issues. Like say you have a problem down the line with say your windows. They might come back and say "your after market exhaust voided your factory warranty" I am pretty sure the Tundra's spare is where the Rado's is so if you don't want a spare that's up to you.

You're saying that you can't put on a one in two out system on a rado? or a Tundra? I've seen both haven't you? And they both had their spares mounted in the factory position. So according to you, these trucks will soon burn up their spares? I've never seen so much disinformation out of an individual before....think it started with the 2wd vs. 4wd in towing and hauling. And before you get confused I own a rado and not a Tundra.
And you DO so own a tundra, just like mine. Stop arguing!!! LOL!!!
This means that A-Trak will not be in 4WD in dry road conditions. When the A-Trak is in 4WD - it is not any more capable than any other part-time 4WD system.
The only advantage of A-Trak is that it does the switching between 2WD and 4WD modes automatically. Although this is a convenience - it does add additional cost and complexity.
I personally like the simplicity of the Tundra's manually selectable 4WD system.
When CAR & DRIVER(?) did a camparo against the Tahoe and Expedition they basically said the Toy's system was NOT good for off roading. They said it wouldn't allow any momentum in soft dirt or going up dirt/sand hills because of the traction control.
I apologize if this is not the same system.
Just when everyone started to sound "reasonable" you go and make a comment like that.
Can't we all get along?
The one thing each of these people told me was that they turned off the Vehicle Skid Control (VSC) off road. The VSC is a lateral skid sensor that is great on ice and wet pavement, but I imagine it would be a detriment to off road situations. Being such a new system, it is likely C&D failed to pick up on this.
By the way... the A-Trac in the Sequoia is identical to the system in the Land Cruiser with the exception that the LC does not have the option of a 2 wheel drive mode and is easier to lock the center differential. Other than that, they work the same.
"Active TRAC
Using sensors at all four wheels to monitor a loss of traction, Active TRAC employs brake and throttle control to reduce wheelspin and transfer torque to the wheel with the most traction."
Active Trac has NOTHING to do with the 4WD system - it is also available on the 2WD Sequioas. It uses the brakes to give it better traction. It does this by applying the brakes on the side which is spinning, this causes the differential to apply more torque to the wheel which is not spinning.
Because of this, you should NEVER engage 4WD on a Sequoia on any surface which is dry. It behaves exactly the same as the part time 4WD system on the Tundra.
The Sequoia does not have a conventional transfer case but rather, an open center differential. Due to this, the braking action of the traction control also routes power front to rear as needed. This is why you can safely drive it in 4WD on dry pavement.
For much more on this system, flip over to the SUV conference and see the topic "Toyota 4 wheel drive systems explained."
They may not have known that.
The only time the traction control is shut off is when you shift into 4 wheel low and shift the transmission into low as well. This locks the center differential and shuts off the traction control.
One part of the traction control *is* turned off automatically when you go into 4WD. That is the throttle control portion. The braking action still happens, but you don't loose power.
When first looking at this system, VSC and traction control are often confused. This is why I gave a complete description in the "Toyota 4WD systems explained" topic in the SUV conference.
The lo feature shut off I like and I would think at Moab a lot of the wheelin' was in 4lo. I tend to do the faster desert type wheelin'.
I always shut off the traction control in the wife's Lexus. I can't stand coming out of a drive and the car's power falling on its face cause I lost traction. Almost feels like you're running out of gas!!
The reason you can safely drive in 4WD in the Sequoia is because it has a center differential. This has nothing to do with A TRAC which is a traction control system.
There is no reason that they shouldn't be able to put A TRAC traction control on the Tundra. It still would not be able to be driven on dry pavement without adding a center differential.
If you were referring to my post to Duckshooter and F1 take better look at the post and the conversation should become CLEAR.
Question:How can on burn up a spare if it has been removed??? I would like you to explain that one to me. And No I never said that. Read my smart pal, read. I said if you put a one to two pipe system on the RADO(I don't know about the Tundra" Then according to several shops you will have to remove those parts off the truck. There is not enough clearance. A full 3 inch dual exhaust is what I as referring to. It also applies to a single 3 inch pipe. And I don't know about you, but I like to have a SPARE tire on my truck. You might just leave it at home since you probably don't know how to put it back on or mount it to begin with!. And Mod, If you're so smart why do you keep thinking your Toyota runs GM Dexcool??? And no I do not own a 2wd anything!!! But you know after all you use GM parts on your Tundra. And I never said it ruins the cylinders smartguy. I said seal and gaskets it will eat away at these things. and Nadhi... Actually Ford has the biggest share in the Truck game followed by the big 3 and then Toyota and others. But I guess it's the whole picture I don't know how they look at it...
"They might come back and say "your after market exhaust voided your factory warranty"
I replied with the Moss Magnuson Act...you should take the time to read it cause an aftermarket exhaust will not void the factory warranty.
You also said:
"What I got when I went to have what you are getting done I was told that they could put it on, but there were problems. They have to remove the spare, The underside mounts will get burnt after time, and then there is warranty issues"
Don't know what shop YOU went too but thats full of it. Single in dual out designed by aftermarket exhaust companies have no problems with the setup burning underside mounts, nor having to remove the spare. Where did you go? Midas?
You said:
"A full 3 inch dual exhaust is what I as referring to. It also applies to a single 3 inch pipe. And I don't know about you, but I like to have a SPARE tire on my truck."
No one makes this as it would cause too much of a loss in backend pressure...2.25" is the max the pipes should be in dual form.
You also said:
"It also applies to a single 3 inch pipe. And I don't know about you, but I like to have a SPARE tire on my truck."
You obviously are misinformed as most of the single in single out are 3". Check Gibson, Flowmaster, Edelbrock....they have no problems installing in place of the stock exhaust...with the spare intact in its original position.
Lastly, have you figured it out that a 2wd vs. 4wd in the same configuration whether it be 3.73 or 4.10, that the 2wd will ALWAYS BE RATED TO TOW AND HAUL MORE THAN THE 4WD
Mod, this is absolutely my last post regarding this....that village better get their's back soon cause the posts are getting more and more dysfunctional.
It's different gearing you putts! Replace a Ferraris Gears with a 4.10 and maybe you'll learn. Do you know anything about gearing?? Amybe that's whyto achive 200 MPH Nascar cars use a different Ratio in Daytona then at the Rock! But it's all the same to you is it not?? Moron... And why don't you and Mod go and tke a ride in whatever it is that you have and do a I don't want to know!
I really fear we are doomed as far as domestic oil supply if this is what's working at it!!!
As far as giving up........I concur.
I'm sure this discussion on GM gear ratios, 4x2 vs. 4x4 for towing, dual exhausts, and melted spare tires on the Silverado would fit in better in one of the Silverado topics, wouldn't it? And ak4x4, I'm sure your vast intellect and clear concise writing style would be much more appreciated over in one of the Chevy topics.
I've always wanted to visit Alaska, but now I'm having second thoughts.
How about let's getting this thread back to the topic at hand: Toyota Tundra OWNERS: Rate Your Truck!
The only thing I'm going to say at this point about the Tundra is that after having mine for 2 years to the day tomorrow and having put 26,000 miles on it, that I can't think of another truck that I would rather have for my current needs. No regrets whatsoever on my purchase.
Alan
I'm thinking it would fit better on the wall of the boy's bathroom at the junior high school he attends.
kip
Mod, do you know the name of that village?...I seriously need to call them.
Arkie: I never said it would melt the spare! Where did you get that?? I just talked about removing the spare. with Dual's on the Silverado a full 3 inch dual system would work, but they have to custom bend the pipe on the driver's side to get around the spare. They simply reccommended that I take it off like other owners have to make the system fit.
And Oby:When I said "Mutt" engine I was referring to your 2500's engine/tranny setup. If you indeed have the Allison tranny. If not then disregard the comment.
And thinking off the top: If you put a full 3 inch dual exaust close to the spare after time the rubber would actualy start to melt. Those who don't belive me do this: Take a old used tire and then take a lighter to it. Hold the lighter there for say 10 min or so. The rubber will start to melt. I am not saying it will melt to the point where you cannot use the tire, but a portion will be melted.
