Sounds like you need to get your speed sensors looked at. Maybe the sensor has gotten shifted or there is debris on it causing your AWD to do weird things. If it thinks your getting a lot of slippage on one wheel from a bad signal havoc will occur. You can do this yourself if you do some research on proper installation and testing. Brake clean will clean the sensor as well but on stands, safely with redundant precautions in place, with ability to rotate the wheel, to spray the ring, and removal of sensor for cleaning yields the best results. If that doesn’t fix it you may need to get it on a computer and see if the abc’s of the AWD are having issues. Good luck!
