Question about 2003 Mercury Mountaineer

1 Answer

AWD acting like all wheels are locked up

Going around a corner, the car feels like a 4 wheel drive truck locked in 4 wheel. On dry pavement, you can hear the tires chirping as the car is slowing down. The car feels like you have one foot on the brake pedal. Pulling into the driveway or a parking space the car will actually come to a stop. When the steering straightens out, you can hear and feel a soft grinding sound.

    I flushed my radiator and now my truck has a miss/etc. Kinda feels like the 4 wheel drive is on, or the tires are not balanced or transmission is sluggish

  The clutch in the transfer case is burnt up and fused together therefor binding the powertrain. If you continue to operate it like this it will destroy the front differential and possibly the rear differential. It was most likely cause by the tires not having equal circumference either due to a mismatch of tires (different brands although the same size is indicated on the side wall will have different measurements,I have seen BF Goodrich tires have a different size because speed rating was different although the model was the same) or lack of tire rotation during the life of the tires.. If the measurements are not with in 1/4 inch around the center of the tread this will cause your concern. Tires should always be replaced at all 4 corners on all wheel drive vehicles.

When I select 4 wheel drive, why does it feel as though it is binding or dragging and whining while driving?


Depending on the specific vehicle many 4WD have a transfer case that will lock the front and rear drives shafts together. This configuration is only for slippery conditions like ice and snow or very wet or off road. When turning the radius is different between the front and rear so there is a lot of feedback to the steering wheel. This is created by the fact the front set of wheels and the rear set of wheels must make the same number of turns because of the locked transfer case.

If you attempt to drive on high friction surfaces the stress to the drive train is excessive and will cause damage. The whine and the bunny hop is the drive train attempting to release this tension. If you were on a slippery surface the tires would have much less resistance turning at slightly different rates.

Also critical is the tire size need to be the same. However even with perfectly matched tires the problem on dry surfaces remain the same.

The AWD vehicles are equipped with a third differential that allows for the difference between the rotation of the drive shafts so it can drive on dry pavement no problem. Some configurations allow the AWD to have the transfer case locked which falls into the first category where dry pavement is prohibited.

Some Jeeps have a viscous coupling in the transfer case that permits limited slip between front to rear but the resistance to slip increases as the deference increases as in the event one tire is slipping
These Jeeps still have the lock up option in the transfer case requiring dry pavement when engaged.

Hope this helps?

2007 jeep liberty stuck in 4 wheel drive


did you drive to dirt and see if it unsticks?
try side of road , at dirt.
first off,
no 4wd system stated, which kind.? and WHAT MODE?>???????
and if using locked mode, 4wd it not for pavement, and will do damage using locked mode, or part time 4wd on dry pavement , no ice means dry. at the least its dangerous. using locked if you dont know what you are doing, use AWD.

why are you in 4wd, do tell?
see the word CANT here.
read it and believe it.

http://en.wikibooks.org/wiki/Jeep_Liberty/Transfer_Cases


use only AWD (if you have it) on dry pavement
or as the lost operator guide told you... .lost that , even read it yet?

Jeep Liberty 4 Wheel Drive won't engage


part time or awd ?
do no engage part time 4wd on dry pavement.!! only on ice or dirt.
do post what your tires are touching? dirt or pavement????????

if stuck in 4L , on dry pavement , pull over to side of road, dirt
then shift out. if no dirt anywhere? sand or gravel or grass.?
then jack up one wheel then deselect 4Low. back do 2WD
options for your car, (do post what you have)
qoute sales brochure:
Those going 4WD can enjoy the standard Command-Trac II, or opt for the Selec-Trac II, featuring full-time AWD, 4WD Lo and a rearward-biased torque split. (end quote)

how you drive both cars, varies greatly.
in your glove box is an operators guide , did you read that yet
under how to drive in 4wd or awd.??????????

DO not use 4wd on dry pavement. do not. its for
ice, snow,or dirt.
if you do that and make a turn , it winds up the driveline. damage.
put in the dirt, at side of road, and get it out of 4wd.
read the manual on part time 4wd, its not AWD and has no center diferental to drive on hard pavement.

see stop driving. ..here

Are awd drives as good as 4 wheel drive ?


Depends on alot of t hings.
All wheel drive means all four wheels are pulling all the time. 4 wheel drive means you can shift the transfer case to make all 4 wheels pull, but not on dry pavement.
Most all wheel drive systems use clutches to allow the wheels to make turns and handle different road surfaces.

Hi,
Yes, this is normal while in four wheel drive on pavement.
I will try and explain why.
In four wheel drive the front and rear drive axles are linked together by a chain in the transfer case and gears in both axles. This is a direct link with very little play between the front and rear axles.
When cornering a rear wheel will spin faster, or slower depending on the direction of the turn. this causes a binding in the drive line because the drive line wants all the wheels to turn at the same speed. So the wheel "skipping" going in reverse, is the drive lines way of compensating for the different speed of the wheels turning.
Never should a four wheel drive be used on dry pavement. I could cause a break in one of the drive line components. On a slippery surface , snow, mud, gravel, grass, There is enough slippage in the surface to aloow the driveline to compensate for the different speeds of tire rotation.
So do not try at highway speeds on dry pavement.
Your four wheel drive system is working just fine.

When I'm in 4 wd the front wheels feel like the brakes are being applied when I make a sharp turn. No problems when driving straight or in 2 wd.


It sounds like you are driving in 4wd drive on dry pavement. The front drive axles do not work like the rear differential. When you turn, the outside front wheel must travel farther than the inside wheel, therefore they are traveling through the turn at different speeds. If you are on dry pavement, this causes the gears to bind. You don't notice this on slick surfaces because the outside wheel will slip instead of bind up the gears. You should not use 4wd on dry pavement. That's the advantage of push button, or shift on the fly, 4wd. You can shift back to 2wd when you encounter dry pavement. All wheel drive vehicles don't have this problem because they have a limited slip front differential as opposed to a locking differential on 4wd. Hope I didn;t confuse you too much.

While in four wheel drive and turning is it normal for the front wheels to grab?


While im not versed in the newer systems most 4 wheel drives will grab while turning on pavement. on older trucks it is caused but both front wheels moving at the same speed. When you turn a corner the outside wheel of your truck has to turn faster than the inside.most manufacturers recomend not engageing 4 wheel drive on dry pavement .

4 wheel drive lock up


hey charlie, 1st problem is 4 wheel drive being engaged on dry pavement. You should only have it in 4x4 in snow, or off road on sand, dirt,etc. Newer all wheel drive vehicles compensate for the tires rotating at different speeds, like going around a sharp corner. The wheels on the outside of the turn have a longer distance to travel than the wheels on the inside of the turn. This results in the vehicle feeling like it's jumping, hopping or jerking as you cut a tight turn. You can damage your 4x4 system, as the wheels are fighting each other, trying to turn the same # of rotations, and something can and will give (like blowing the transfer case). If your light is staying on after changing to 2 wd, it is possibly stuck in 4x4. To shift from 4wheel to 2 or 2wheel to 4, you should be traveling in a straight line, let off the gas, change in or out of 4x4, resume driving. 4x4 low range requires a complete stop to engage.
