So first day at the dragstrip after boosting. Eased into launching from idle then seeing how hard I could go, balancing grip vs power. Left around 2600 and it bounched and shuttered like wild. I backed out and stopped for the day. So driving home, when turning it feels like the wheels are going to fall off. Pretty much a 180 in a parking lot at idle speed is brutal. Took it to a shop who put it on a lift and said something is broke in the diff. All I could really get for free on short notice. Drove it two hours home. In a straight line it felt fine. Would kind of sway and feel like the wheels would spin for no reason but straight line driving was ok. But ANY type of turn the wheels shutter, bounce, etc. So is my diff likely destroyed, partially destroyed, maybe axles popped out a little? I won't know till monday but just trying to see my options here. Visibly nothing appears broken and no fluid leaks.
