i had a bad cv causing the car to shake about 2 months ago. i got a new one and got it put in and a week after it was put in (was put in a month ago) it started to shake again at 60mph. then 2 weeks later it started popping when i turned really bad. saturday i was at the track. dopped the clutch at 2,000 and it just sound like grinding gears. so i figure i wasnt in first. but i was in first because when is staged i never took it out. i pus the car off the line and put it in first again and it goes NOWHERE! i toe it home.... when i ease off the clutch i hear something start to spin up but the car doesnt go anywere... is it my transmission or did my cv axel just break?
