I I have a 2006 X-type that I believe the front wheels are not turning in all-wheel drive. How does this system work does it use sensors or do they turn all the time. I'm not sure if the rear wheels turn normally then when a computer or something sees that the rear wheels are turning faster than the front it locks the front in the car runs perfectly fine with no noises or anything

 

springer, the AWD system is always active. It splits the power 60/40 (front/rear). Because you have an 06, you have to remember that because the transfer case is essentially an open differential, when one wheel (whether front or rear) looses traction, 100% of the power will go to that wheel. So, this somewhat defeats the AWD system. The exception to this is if you have DSC (dynamic stability control), then when it sees the one wheel loose traction, it will apply the brake to that one wheel, therefore slowing the wheel down and transferring power to the other wheels. Then, with time, the braking applied to the initial wheel will be eased to see if the wheel has regained traction.

So, if you were in a slippery situation, it is very possible that what you experienced was "normal" for your car. If you are in this situation again, try riding the brakes a little bit when you start feeling the tires loose traction. This will help keep the wheel spin to a minimum.

 

If you are driving the car and don't here a whole lot of outrageous noise coming from the drive train then the all wheel drive is working. The drive wheels are constantly engaged. The dsc and abs apply breaking to control the wheel speeds.

 

I have an abs and brake light on. My ABS is not working. With that being said will my AWD work as it should or does it use the wheel speed sensors to regulate power to the wheels.
Thanks in advance

​​​​​​I guess you don't have an actual answer? Glad I could make you chuckle seems like you have nothing better to to in your life but answer questions with smart remarks that are no way helpful.

 

Not really crazy, plenty of cars have computer controlled AWD that uses input from the wheel speed sensors to engage AWD. When the sensors on the wheels of one axle detect wheel spin there's an electronically controlled clutch pack that will engage the other axle. These same sensors are also used by the ABS system. When a sensor goes bad, which is pretty common, it will throw both an ABS and AWD Disabled light. This type of system is traditionally for poor weather traction since it works in a 'slip and grip' fashion (though modern ones can engage the clutches proactively based on various parameters). The X-Type system is mechanical as you mentioned, which is much more suited for a performance oriented AWD system (though some X-Types also have a DSC system which can also brake a spinning wheel to further aid in traction, which would be disabled if ABS isn't working)

 

Shame how someone that may be capable of helping would rather be a smartass.

Especially when the non-answer gives the impression of a lack of understanding of the possibilities anyways.

 

thank you for an answer that is helpful! That's what I was looking for. Yes I wasn't sure if the ABS had anything to do with a non DSC car because it does have something to do with A thaDSC car. That was my question. Thank you.

 

Hi springer,

I have merged your two threads so all the replies are together.

You can find some information on the operation of the AWD system and which aspects of the chassis performance are electronically-controlled in these documents:
