Exclamation When in 4x4, I can't make a sharp turn! AHHH!

Hi I'm new to having my jeep. I broke her in a few months ago. I took her to the desert. It was great. Then I noticed, a month after I got back, when I had it in 4x driving on the road, when I would try to make a sharp turn, the wheel would jerk and pull. Note, it doesn't do this when in 4x2. Please if you can give me some advise before I take it to the dealer, that would be awesome!

You should NEVER drive your Jeep in 4x4 while on dry pavement. This causes binding in the drivetrain because of the different speeds your tires are going when you turn, and puts a lot of stress/strain on your ujoints and transfer case. You are feeling your drivetrain loading/unloading when you make a sharp turn on the pavement in 4wheel drive. You don't feel it in two wheel drive because the tires are allowed to turn at 4 different speeds without any load on them (except in the rear). Always leave your Jeep in 2 wheel drive unless you are off-road, or in a limited traction situation (snow/ice) on the road...

What Jeeperman said. Don't worry about going to the dealer.

Thank you!

Hey thank you so much. Sorry for my ignorance. The only reason I had it in 4x on the road was because it was raining really bad. So my truck is fine then? Thanks again for your help guys!

Yep. Sounds fine, and you are not ignorant. Many people aren't aware of that. Luckily, you found out before causing any serious damage.

The reason it does that when on pavement (even when it's wet from rain) is because the Wrangler's 4x4 system mechanically locks the front and rear axles together so they are forced to rotate at the same RPMs. When you turn left or right, the front tires need to rotate faster than the rear tires. So when they are prevented from doing so while you're in 4x4, you will notice a lot of bucking and steering problems.

This doesn't happen offroad because the poor traction there allows the front and rear tires to slip against each other when needed.

The above problem is a trait of a "part-time" 4x4 system like the Wrangler and many trucks have. Some vehicles have "full-time" 4x4 systems that don't mechanically lock the front and rear axles together so they are free to turn at different RPMs when needed.

thanks Jerry

Thanks for your help! You are very informative. I appreciate that. Hey I noticed you live in Escondido. I'm planing a trip out to Anza Borrego within the next month. Do you know of any good offroading trails. I have a stock '04 Rubicon.

thats the one thing i miss about my Grand cherokee when i had that...had the selec-trac t-case to it had not only the part time, but also the full-time 4WD...that was the ideal t-case in my opinion

and dont worry orion...what you did is all part of learning what 4wd really is.....i did the same thing in my first jeep

if you got any more questions, keep 'em comming!

Anza Borrego has a ton of trails, a good one to start with would be the lower half of Coyote Canyon that starts just outside the city limits (just past the traffic circle & turn left) of Borrego Springs. I believe the upper half of that trail may be closed but I could be wrong, I can never keep up with the environmentalists and what trails are closed. The area around Ocotillo Wells campground area is very good too, just keep track of where you are so you don't get too lost. If I wasn't working Saturdays, I'd be all over going out there for the heck of it.

This is evidence of the value of maintaining old topics. I ran into this same problem last night while trying to do some snowy hill crawling on the large hills separating different levels of a parking lot. I only had the binding problem after my first attempt to mount a very steep snowy hill and I thought that had caused it! I went home and checked for any rubbing in the wheel well etc and found nothing that would touch. To say I was relieved to read this thread would be a huge understatement! Thanks guys!

The best guide I've read about all the different 4WD is simply the 4WD wiki.

Four-wheel drive - Wikipedia, the free encyclopedia

it explains what the difference is between 4wd FT/PT and AWD - and why my Commander sucks off road compared to the Wrangler.

Even on soft soil, or snow/mud, I find that I can't make as sharp a turn in 4X4 as when in just 2X4 drive. And I always wondered why the dash light showed "Part time" when in 4X4 since the front wheels where pulling all the time. Always seemed like a misnomer to me.

The lower part of Fish Creek (Up to Sandstone Canyon) is beautiful and a very easy run. There are the Wind Caves, Elephant knees, and many other little places up there.

to the OP: Don't worry, you're not ignorant at all. This is a good place to ask questions and learn from those who have been in your shoes. Also, if you have your rig in 4Lo, the steering can get even worse. If you're on the trail on a tight spot where your steering might bind, it's ok to put your rig in reverse and do a 3 point turn
