The DSC button on dash will disable DSC and illuminate the triangle. Verify your DSC triangle lights when you start the car.
Are you on a low friction surface when you experience this?
A couple of diagnostic concepts:
1) pull the fuse that disables the front drive. You can confirm if the problem is from the front wheels.
2) disable DSC: if you are correct and it's working but the light isn't, you can determine if some part of the system is working or not
3) as mentioned earlier, in pretty sure it's some form of the differential trying to turn the inside wheel faster than the left; drive in a circle on low friction surface: sand on assphalt is perfect: properly operating did will allow the inside wheel to lay down a clean tire track, if the dif is putting too much torque to the inside wheel the track will not be clean.
If there is just a tiny bit of over rotation on very tight turns, as long as your tires aren't wearing it could be ok. My Camaro spun the inside wheel (with shudder) any time the surface wasn't perfect since the dif was set up to give equal power to both drive wheels.
When I lost the shudder it was time to have the dif serviced because one wheel would spin and the other would get no power. Possibly you could have less than optimal grip tires? The tires that came on wife's car I wouldn't put on an old vw bug.

So when I try to kick it out and slide, I have yet to see the DSC yellow triangle light up. When I start up the car, it definitely lights up and goes away. When I press the DSC button, I get nothing on the dash...
I have felt this in complete dry conditions in the summer, and I feel this in low friction surfaces such as snow and ice that we are dealing with now. No difference, same shudder.
Will have to try some of the diagnostic options you mentioned. Where is this fuse that disables the front drive? So it would be a complete RWD system then? Any adverse effects of driving it like this?
How to disable DSC, if I am not able to get it to light up. I know you can hold the button down for 10-15 seconds and turn it off completely, but if it doesn't light up, what else can I do?
Will try the driving around in tight circles later on today and see what kind of tracks it is laying down.
Tire grip should not be an issue, because I just installed brand new Bridgestone Blizzaks!
Thanks!
