Car gets stuck in the snow. Its front wheel drive and only the drivers side front tire will spin and not the passenger side, shouldnt both be spinning if its stuck to try to get traction?
No, even a 4x4 will have only 1 wheel that will spin on each axle in this instance. It's called a floating differential. For stock vehicles with non locking differentials like you have, both cannot spin or have full power at the same time. Hard to explain on this, but picture your car making a hard right turn. Both front wheels would be spinning at different speeds because of the turn. The passenger side tire is spinning much slower than the drivers side tire, therefore if both were spinning at the same time, your tires would chirp and skip on the pavement which would eventually ruin your differential. In offroad applications, we WANT the differentials locked and turning at the same time with true 4x4. But in normal everyday vehicles, even standard stock 4x4's, only 1 tire will do the spinning per axle unless it has possitraction or full locked axle. Clear as snow?

this transmission has a known fault with the awd section of the transmission, it is quite common to find the fuse out, because at somepoint in the life of the car an expensive repair was required and the owner did not want to do it, no fuse awd does not work end of problem. Put a fuse in, if the vehicle then judders on full lock in reverse or going forward, the fault is the awd solonoid block, depending on how long it was run in this condition, will depend on how much of a repair will be needed. Find a reliable transmission repiar shop and get a quote, not knowing were you are i cannot say with local prices how much it would cost. Hope this helps.

Did you have this problem before you got the tires? Sounds to me like the tires need to be balanced.
SOURCE: How does 4 wheel drive work?
Hi there , in order for your 4 wheel to work you have to drive a couple feet for everything to lock. If you are already stuck and you put it into 4 wheel, it won't engage. hope this helps you out

The 08 Vues AWD system is very different than from previous models. The
new Vues system is more like the technology on the Outlook. I' don't
know detail on the hardware, but from a function standpoint there are
two big differences:
1)The system is PREDICTIVE, not reactive. It does not wait for
wheel-slip to make it engage. The system monitors throttle position,
steering angle ect. and re-directs torque before wheel spin occurs.
2) The old system sent extra torque to the wheels that were slipping to
boost traction. The new system sends power to the wheels that are
gripping.
The result is a better, smoother system that will do a better job of keeping the Vue from getting stuck.
The old system was a single gerotor type AWD system. Essentially, a
gerotor AWD system uses differences in rotating speed to spin a pump
and apply pressure to clutchs. The single gerotor system used in the
Vue essentially engaged and disengaged the rear axle when a differences
in rotating speed occurred between the drive shaft and rear differential
(indicating the front wheels were spinning faster the rears). From here
on out, power goes into an open differential and was distributed
accordingly (i.e. not very well).
GM also uses a twin gerotor system in the form of Versatrak. This
operation in much the same manner, using a difference in rotating speed
to spin up a pump and apply pressure to clutches, except the Versatrak
system has a pump for each output axle. This allows the rear differential to act of each rear axle much in the way a limited slip
differential does, better managing torque distribution.
The new system used in the Vue (as well as the Outlook, Acadia, and
Enclave) is controlled by a microprocessor and operates by means of an
electromagnetic clutch. It is very similar to the Haldex system
marketed by Haldex Traction AB. The main difference being that Haldex
still uses hydraulic pressure to apply the clutches, while the
electromagnetic system used by GM (which I believe is developed by Borg
Warner) uses electromagnetic force to apply the clutches. The operating
principles are the same though. The new GM system is well integrated
with stability control, traction control, and ABS. The system actively
monitors vehicle dynamics and driver input to determine when to being
engaging AWD before it is actually needed. With the ability to
manipulate power delivery using AWD and stability control (by selectively applying brakes at each individual corner), the new Vue is
very robust in terms of torque management. For all you folks in the
snow belt, it should be dynamite in slippery conditions!
Hope this helps answer your question. Good luck and be safe on the snow.

It sounds like your limited slip differential is in need of a fluid change.
The clutch packs in the axle require a special friction modifier,about 4 ounces added to the axle lube,which fixes the chattering issue.
I'd suggest someone drop the axle diff cover and check or change the
fluid,to see if there are any big metal pcs. in there. If there is no damage,drain the diff fluid and add the friction modifier,only if a SLD..
Note: Only add the friction modifier,if you have a limited slip differential.
Since I can't physically see your vehicle,make sure a mechanic does
it right.
