4H Turning Issue?

bubert · 10-29-2009, 04:53 PM

I've noticed that when i'm in 4H and i make slow, sharp turns (such as turning into my driveway), the vehicle really seems to bog down and even starts to "jerk" a little bit. It's as if somethiing is binding. I don't see anything in the manual indicating that i should expect a problem in this condition. Is this normal?? Are there driving limitations in 4H?

Stop doing this. The only reason you should be in 4H is if your offroad or on a surface that can slip. You can cause big problems turning like this because your wheels will all bind up and snap things. Are you just on pavement? because if so leave it in 2H

I was just following the directions in the manual to drive in 4H 10 or so miles every month.....

I know what you're saying, and it's been discussed on other threads. I try to do the same thing, but only do it on long straight roads. When you're in 4wd, both front wheels turn at the same rate, so when you turn sharply on a hard surface, the wheels rotate at different speeds, causing the binding that you're experiencing.

So if you're gonna do your 10 miles in 4H every month on pavement, which is often unavoidable, make sure you ONLY DO IT IN A STRAIGHT LINE and shift in 2H when you need to make a turn.

You need to be in sand or snow in 4Hi or Lo, If your on a hard paved surface things will bind in your transfer and you may damage things. Read some more !

Where can you possibly live where there is no option of gravel or dirt or sand or grass, etc. to drive on???

I bet 10 miles (or even 5) of dirt or sand or grass etc is not readily available to many people. Ask anybody that lives in Manhattan.

Ahhh, Manhattan....a good location for choosing an FJ.

They changed the owners manual in 2009 and they removed the warning about NOT using 4H on dry/binding pavement. If you look carefully, you will see that they kept it for the MT6 in HL, which is essentially the same thing: transfer case locked to provide 50/50 rear & front.

I challenged Toyota Canada about this and they said that it was not a mistake and that I should follow what the manual said. IMO, they just don't want to admit that they made a mistake. But in doing so they opened themselves up for big lawsuits...

In the mean time, you should refrain from running in 4H on dry pavement. As your post point out, you are experiencing binding on thigh turn, which is not good for the drivetrain. You should wait for rain or snow, or better yet, go off-road :-)

I should receive my 2010 soon and I will check the manual to see if the warning made it back or not :-)
