No Limited slip on 4cyl 4x4's?

I did not need to read the "whole thread" to know what "the question" was.

As you stated "So the question was a generic what is best......" I am wondering where you came up with this? This was not in the original post, or how most responded to the OP?

 

HMMM, maybe you do need to read the whole thread. This was the most recent question asked, and the current item being discussed, this is not complicated...Quit highjacking, either add to the discussion or leave, thanks. The above question was the one being discussed.

 

Did I say I did not read the whole thread? In fact I did, and your the only fool here!
Just because the person who started this post owns a different truck then what stated he wanted information in the OP, where did your "stated question" come from?

 

Do you even know what highjacking a thread is?

All the information I have contributed to this thread is real and accurate. This is however a perfect example for those who are considering seeking valuable and good information on the web to beware... alot of opinions out there...

 

Done?

 

I'm still trying to get my head around this as well. I'm reading different threads explaining what the TRAC/VSC/AutoLSD do, and I think I get WHAT they do. Why is a completely different thing.

Obviously these things are for driving in semi-normal situations, i.e. not rock crawling. Soooo, why the heck should you have to ask your truck with a computer for a brain to please stop slipping a wheel?

My 09 Access sits in my driveway with one crappy stock Dunlop on packed gravel, and one on ice, slightly uphill. 2WD start, ice wheel spins away, nothing from the other at all. So I now understand that I must ask my truck to please do something different by pressing the little button with the squiggly lines (VSC) to remedy this. Does anyone else agree that Toyota was working the crackpipe on this design day? I could buy that if it worked automatically you could turn it off it you wanted, but that's not what it does. I would think a sensible plan would be to first brake the slipping wheel (electronic limited slip?) and THEN cut power for both if it continues (losing control, drift, etc.) If you wanted to kill the power cutting part, a button for that would make sense. But why do you have to ask to control wheelspin?

I'm hoping for an explanation that makes some logical sense. Hope this isn't too big a hijack.

Thanks in advance.

FWIW, got some A/Ts today, so my ole Dunlops look more rediculous than ever!

Thanks.

The system does transfer torque, before cutting power. I find that given a few seconds, if there is any traction, in normal drive mode, the truck will slowly pull away, with very limited wheelspin.
The VSC button does exactly what you are asking for, what is the issue? It doesn't turn the system off, it bypasses it one stage at a time.
I think the system is very well set up. I find it is on the conservative side, by that is perfect for my wife, and the many drivers that have little skill.
Could you clarify the question?

 

Thanks for the reply. I suppose the direct question which maybe none of us can answer is why isn't the traction control automatic? At least on my truck, when one wheel has adequate traction and one has little, regardless of how long I stay on the throttle mine (2009 4x4 AC 4cyl) transfers none of the power to the wheel with traction. I'll spin all day as I have done previously to see if maybe something might change. It doesn't. Am I reading that in normal drive mode yours would?

I do fully understand that the VSC button activates TRAC and deactivates VSC, supposed to anyway, although I haven't found it helped me either. 4WD does, but with one rear wheel on dry and one on ice, I go nowhere without 4WD. I don't get it. Maybe mines faulty?

Thanks for your thoughts.

I just don't seem to find what I'm reading I'm supposed to find.

Thanks.

See my signature below, I had many questions as well. If you are getting a Tacoma for the trails, then get a 4WD! TRAC (H4) and A-TRAC (L4) work awesome... I had lots of fun testing my new Tacoma out in Baja over New Years, in deep beach and arroyo sand. They work superior than my '05 and '01 Tacoma. No air needed to be let out of the tires with the new drive system for deep sand. Isthatahemi has good information, as well.

 

Hi Matt... Always use 4WD when you are not on dry pavement. Pickups by nature are driven from the wrong axle if the bed isn't loaded (most of the time for most of us). Go to H4 (TRAC is active) and you will have no issues anytime off highway.

In fact, for pickups it would be great if we could choose to be in front wheel drive (where the engine weight is) when the truck bed is empty and go to rear wheel drive only when the bed has a load (on dry pavement).

Hope my stuff below helps, as well!

 

It states in the owners manual that Auto-lsd is for this type of situation. Maybe this is a small flaw, in that normal VSC/TRAC mode is not effective in this one particular situation. But given that the Auto-Lsd mode is present, why not just use that? If A-LSD doesn't help, there may be a problem. Nothings perfect.

It would help if you filled out your profile with your year make and model.I'm assuming 09 AC 4X4 4cyl 5 speed....
