Driving home today I pulled out and had to accelerate hard, noticed front tires starting spinning then a pop noise as i was letting off the gas. I thought I hit a pothole so drove the rest of the way home like 10 miles or so on the highway it felt fine. Pulled into a snow covered parking lot and confirmed only front wheels have power.

Taking it to the dealer tomorrow to see if it's the collar or entire angle gear. I have not noticed any noise or vibrations and been changing and checking the fluids as well.
