2000 astro awd wheels bind when turning sharp

on dirt? off road or on the road (pavement)

on ice?

do say what the tires are touching. we cant see you drive.

this car has parttime 4wd, its not AWD nor full time 4wd.

sorry, its PT. and the rules for PT always apply.



Part time is not for dry ice free pavement, at all.

if you do this, it winds up the drive line and causes the gears to lock. and worse.

the lost operators guide explained all that.



and needs to back up to unlock the front axle locks.

one more pain.

4WD S model, which used manual hubs, get out and turn dial.



so if doing all this wrong, on dry ice free pavement???

move car to shoulder that has dirt ./sand or gravel on 1 or 2 right wheels, then shift out of 4wd to 2H

or damage the transfer case you will.

like this guy did.

turn steering only slightly off center to get to curb, or it gets worse.

symptoms of bad drivers.....using 4wd, PT.

steers gard

funny sounds (of death)

gears lock up in transfer case or even in the manual trans.

or far worse.

If you turn sharp corners in 4WD, it is normal on dry pavement.

Hello Joe.
please say what works and does not.?
and on what road surface you are on, pavement, dirt, ice? what?
and what does winter mode mean. tell actual shift modes.
and what transmission options you have.

no do not rebuild anything, first is diagnosis.
never guess. or go broke fast,

• 130-hp, 2.2-liter I-4 (regular gas)
• 205-hp, 3.2-liter V-6 (regular gas)

• Transmissions:
• 5-speed manual w/OD
• 4-speed automatic w/OD

4x2
4x4
limited slip diff option?
Mode select transmission? option 4x4
this is part time 4wd and is not AWD , all wheel drive.
as such it is not for dry (ice-less) pavement and is for offroad.

so what surface are you driving on. 1st.
then in what mode.
are you messing up and using 4x4 on dry pavement
see here for what happens doing it wrong.
http://www.rubicon-trail.com/4WD101/driveline-bind.html

if you wind it up. the gear shift can lock up.
the solution is 2 ways.
drive to dirt shoulder and move slow and shift back to 2WD.
or if can't do that. (no grass , ice, no dirt)
jack up a front tire. and do same.
this unwinds the system.
then shift to 2wd.
some rare cars have partime system with a hidding slip clutch that
prevents wind up. this car dont.
nor does car have an AWD center differential.
good luck.

Hello, Yes, It sounds like it is in 4 Wheel drive mode. Your vehicle will not make as sharp of a turn when in 4x4. You should be in 2 wheel drive on dry pavement. If you have the other system called All Wheel Drive, yours would be binding when it should not.

Check your Range Selector for the different settings. When in 4x4, the vehicle is made to take gradual turns so you don't flip it on a hill. Sometimes people mistake the Range knob for the Fan Blower switch.

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.

The front differential/drive train have no way to slip in four wheel drive. When you make a tight turn the the front wheels travel a different distance than the rear wheels. on snow, ice, mud, or other off road conditions this isn't a problem because there is less friction for the tires and they just slip a little without much indication they are doing so. On dry pavement they cannot slip and cause the front drive train to bind up and eventually hop.

By the way that is not very good for the 4X4 drive train in general so unless you driving a straight line on dry pavement I wouldn't recommend using the 4x4.

In two wheel drive the front drive drain can move independent of the rear drive train so tight turns are not a problem.

you need to check the front axle U-joints out by the wheels,they start to bind up when you make sharp turns,the U-joint won't flex and will need replaced

Binding on tight turns are usally caused by a fault in the transmission tail end.
You can check in the following order.
1. Trans fuel level/ Change several time to flush the system..
2. Speed Sensor that sits on top of the tail end.
3. Duty-C Solenoid inside the tail end
3. Clutch Pack

it is a part time 4x4 .it is meant for ice,mud,snow gravel etc.
do not use on dry road.
the wheels are locked together and in a turn the outside wheels have to turn faster and they can't.
that is why there is hopping in 4x4 when making a sharp turn on dry pavement.pressure builds up in the driveline until the tires slip on the road.
only full time or awd systems are for dry road,they have slippage units so the pressure does not build.

Do u have it in 4x4 on dry pavement? If that's the case, u should use 4x4 mode only in snow, off road, etc. The 'problem' is that all 4 wheels are trying to rotate the same revolutions , and the 2 wheels on the inside of the turn have a shorter distance to travel. This usually results in a sort of lurching feel as the truck goes forward, sort of like it's being held back. Does this sound like what's going on? If it does, just avoid sharp turns on dry pavement when in 4x4. Let me know if this does not help.
