On my drive to the gym last night I stopped to fuel up. Leaving the station I made a 45 degree left turn and accelerated into the lane. I felt and heard a big clunk (like if you were running over a box of shoes) and immediately something was not right. I had no lights on the dash and the car felt fine, at this point I was babying it to the gym. Getting off the highway about a mile later I realized something was not right, particularly when taking a hard left or right at slow speeds and feeling like my wheel was loose and about to fall off (my initial thought). Drove home and today I replaced the drivers axle shaft with the same noise and feel at slow speeds with the wheel turned left or right almost full lock. I put the car up in the air and did some tests but was confused when the back wheels weren't spinning? Aren't the rears supposed to spin when there is no traction up front? I also heard this noise that only happened when the car was up in the air. At this point, I'm pretty lost on to what the culprit to the problem could be. In park off the ground, both front wheels and rears spun freely which I don't think is right. Driveshaft is not loose or have wiggle room around angle gear. But slowly turns when the car is in drive and idling however the rear wheels don't move at all. VIDA shows nothing and no faults. I got this car with 68k and have done two transmission flushes since (105k now), transmission has no issues. I've topped off TC with gear fluid around 80k miles. I did have an issue with my AWD module that I replaced and filled with correct level fluid (or so I think). I will be checking fluid levels tomorrow. Any thoughts on what's going on? I did take some quick videos to help share an idea of what's going on.
