4H driving problem

Anyone ever experience problems driving in 4H?

Did that the other day and when I turned the wheels it came to a stop, like the brakes were being applied.

I read some stuff on line where people said you can't drive 4H on dry pavement. That sounds ridiculous.

 

No 4wd on dry pavement unless you want to chance breaking something.

The feeling you're getting is the driveline binding.

 

This is normal for a 4WD.
4WD is intended for off road driving. The front diff is a locking type.
4WD is not the same as All Wheel Drive in which case the diffs allow for slippage to compensate for the different turning radius' of the inside wheel vs the outside wheel.

 

So, only on gravel or mud? What about a hard fire road, seems like it might bind up too. Is this normal with all 4x4s?

 

As Festerw has pointed out...........YOU'RE binding the front drive system Dog. Stop. Never run it in 4H OR 4L on dry pavement. Bad. Bad. Bad.

EDIT: loose gravel and mud are a different story. If the "outside" from wheel/tire can "slip" than you're probably O.K.

 

If you're on a hard road there's nearly no need for 4wd.

I leave it in 2 until I feel it start to slip.

 

Ok. I get it now.

I just wanted to see if it would work. Hope I didn't eff anything up.

 

This is weird reading this thread, I can switch mine into 4wd hi on the move and everything is smooth and seamless. Black top or not..

 

Turn the steering wheel...

 

If your talking to me , I have. I drove it around the block.

Hell ! I just remembered driving around a whole mountain side somewhere in Colorado cause I got detoured. 4wd hi the whole time with patches of wet road from the rain and snow. Smooth as silk no issues.

 

Not to be picky, but there's some incorrect info here. The problem is not the front or rear differentials, they are standard open diffs. The issue is that in 4wd, there is no differential between the front and rear axles. In other words, on dry pavement, you're forcing them to turn at the same speed, which is fine in a straight line. But in a tight turn, they cover different distances and it binds up because the tires don't slip on pavement easily.

 

Shouldn't the manual state this, so people don't destroy their drivetrains?

 

Yes, it absolutely should! Why Toyota doesn't say anything about this is beyond me. Here is a great video explaining exactly what a 2nd gen Tundra 4wd system looks like and how it works. It's a training video for mechanics so it's a bit long but it it really worthwhile watching. https://www.youtube.com/watch?v=47m7QAPrpsI

 

It sort of does. Dry pavement doesn't meet the "permit tires to slide" part.

Is a few miles on dry surface going to ruin everything? Probably not, but if someone stuck it in 4h and ran from November to February that would likely do it.

 

If you really want to convince yourself. Head outside, engage 4WD, drive down the road a bit, then try and flip a U-turn. Report back with your findings

 

I'm not trying to convince myself, I really don't care.

 

4WD should be on bad roads...and not full lock to lock in turning...take turns a bit wide and pull through the turn. this is normal operation of 4X4

 

Guess you should read the manual to see if it says it in there or not. (It does). There's also a thing on your visor that says it. So much for personal responsibility.

 

Before you go blaming people for not reading the manual, my 2010 owners manual says absolutely nothing about slippery conditions, or when or where to use 4wd. Nada, zero, zip. And like many others I only found out after trying a tight turn in 4wd. After years of owning AWD, it never occurred to me that it would be an issue. It is a huge oversight by Toyota not to have more information in the book.

 

"Part time" 4WD 101

 

Agree 120%. This needs to be posted someplace permanently. Not sure where, but posted nonetheless. Offroading 101, well stated sir.

 

If you're able to lock you steering wheel on dry pavement and have no binding, you've got some issues with your drivetrain then. Maybe your 4WD is not engaging, any part-time 4WD truck, if you engage it, and try to turn the steering wheel all the way to one side and drive, it'll bind and not be able to move smoothly.

 

if you can turn on dry pavement in 4WD and not feel your tires chirping or jerking around then either your front diff isn't engaging or you have very bald tires

 

When you say lock the wheel, do you mean completely crank the steering wheel to either the left or right ?

The reason I ask is because I don't do that to begin with. But I have engaged 4wd in the snow and on wet roads and driven normally, but no tight turns.

 

wet and snowy/icy conditions are the only time 4WD should be engaged on pavement. (unless you're hooking up to somebody to drag their ass down the street )

 

OK
