Hard to accelerate with wheel fully turned from park after switching to 4x4

bump.

 

Why do people try to use 4x4 on pavement? Seriously, I've never understood it. What actually makes someone think putting their truck in 4LO and then driving around on the pavement is a good idea.

 

Have a buddy with a grand Cherokee, he use to throw it in 4x4 way to often on dry pavement. I have been in it when he threw it into a corner way to fast in 4x4 and it never had a issue. It was stupid yes but when he sold it with over 200k on it and never blew a transfer case or a diff. He said it made it corner better, like I said it was stupid but never broke anything. I did see the post here with a cracked t case from a grand and can't believe his never blew. Now engine, well thats a different story.

 

Oh okay I get where we was going with that

I'm a law student... what are circles?

 

Most SUVs are really AWD, although most people think they are the same as 4WD. Like the ridgeline for example, they are trying to sell it as a 4WD but it is an AWD. I have a Jeep Commander, it is not a true 4WD it is an AWD, but I can hold/lock the rear differential.

I guess even in heavy rain, 2WD is safer.

I plan to use 4WD HI in heavy snow and sand only. I guess we should not even drive it on 4WD HI on the highway (high speed), even during a snow storm? Does anyone drive it in 4WD Hi on the highway?

 

4WD high is great for driving on snow/ice covered roads but in those conditions your going to be driving safely and hopefully under the posted speed limits. It's still a good idea not to make your turns too sharp and get back into 2WD when in tight areas like parking lots.

 

Oh god i think I just cried and puked; hopefully OPs is good

All the time in the mountains in CO when the snow is packed on the road and you can't see pavement. Mostly just for traction to go uphill, not like the jackasses with their AWD audis that think they're invisible.

OP you learned a lesson. Hopefully upon hearing this clunk you didn't try to max out and get rid of it by doing it more.

 

You mean loopholes?

 

Wow, its like watching a squid go and buy a Hayabusa and kill himself.

 

I drive in 4HI on the roads when it snows down here (It isn't that often, but it does happen). Never had any problems. With all the hills around here, if you're not in 4 wheel dig you won't make it up em. It's fine on snow covered roads, but if you have to go full lock for a tight turn, it's best to switch back into 2wd. That's the good thing about on the fly 4wd...easy to switch when ya need it.

Edit: I Mainly posted this just to sub to this thread...wanna see where it goes...

 

I've heard the rumors of this story, now I've read it for myself!

My side is still hurting

 

lol, i dont know what to say here, read the owners manual, its probably the first thing it says under "when in 4x4"

 

"Hard to accelerate with wheel fully turned from park after switching to 4x4"

This is like the guy who goes to the doctor and says "Doc, it hurts when I do this"

Answer: DON'T DO THAT lol, lol, lol!

 

all the tires are locked together and are trying to go the same speed, it puts everything in a bind,i know somebody who dropped a front driveshaft doing that

 

Thanks all. Didn't get a chance to read the postings until now. I did it on wet snow, since its been snowing like crazy up here in Boston. How can I tell if I damage anything? Car seems to run fine after switching back to H2.

I can use H4 mode only in mud or when there's wheel slippage, such as in snowy conditions on highways?

 

Everyone has driven their 4x4 on dry pavement once or twice without damaging but it is important to understand what you are doing. Many of the posts talked about binding. The simplest explanation is that the outside wheel in the turn has to turn faster (bigger circle) than the inside wheel to keep up but they are directly tied together by the differential making them turn the same speed. This is what makes the wheels hop and the grinding noise.

Even wet pavement, snow, etc. is not sufficient slippage to eliminate this and is not recommended unless you are going straight (wheels going same speed). It is better to drive in 2WD if you have to turn but H4 is OK if driving straight down the road.

You are probably fine.... Put in 4H while driving on any surface, just keep it straight. If want to check it turned, get it in some mud.

Has anyone had any issues switching between 2WD and 4WD at highway speeds? Is it ok to go between 2WD to 4WD while driving over 50 MPH? I guess going from 4WD to 2WD should be ok.
--------------------------------------------------------------
I am confused about the TRAC / LSD; if in 2 WD and one rear wheel slips, does the TRAC control all 4 or just the 2 powered wheel? It uses engine and break controls to slow down the wheel that slips. Does it use break control on the 2 front wheels too? or it can apply break control to one wheel only?
-----------------------------------------------------------------
My driving plan of action was: (please comment if I am off):

2WD all the time except:

4H: Snow on the road or icy road (is there a speed limit to drive in 4WD?)
4H: Driving on sand, or mud
4H: Going up/down a hill in slippery conditions(rain or snow)
2L: with locked differential driving on a hill in sand at low speeds
2L: with locked differential if stuck in sand

Any other suggestions?

 

What kinda oil was he running? that chain is really clean

 

First of all, come down to the Cape so I can slap you upside the head! Afterwards. drive it in 4WD on a STRAIGHT ROAD, and KEEP IT STRAIGHT. If you hear bad sounds then you screwed up your T-case. If not then you're probably fine. It still takes quite a bit to actually break your T-case, but you will wanna make sure. With the 6+ inches you should be getting tonight, you will know if you broke it or not. Feel free to drive in 4 with that stuff!

 

^^^ what he said. At least I sure hope so with Tacoma's.

I was always forgetting I had it in 4x4 in my Rodeo and Trooper before that. I put 130K plus on each of them... lots of of 4x4 action in NM mountain snows transitioning in and out of hard pack dirt...then paved...then 20 miles later turning in to a store and OH CRAP I forgot!

I never really worried about it though...just put back in 4x2 when I felt the binding. I hope Toyota's are as forgiving as Isuzu's. They were pretty much bullet proof, except for the crappy GM accessories (like power steering pumps and alternators) that were always giving problems.
