Last night around 10 O' Clock, I launched my car from 2500 rpm. It was standard protocol as far as launches go, rev it up and dump the clutch. When I dumped the clutch and quickly had to shift to second, my car started shaking like crazy. I quickly put the clutch in, stuck her in neutral, and coasted to the nearest parking lot. I got out of the car, and inspected the tires and the motor as best as I could. Finding nothing, I put her back in gear and backed out of the parking spot. When I put her in first, the car started shaking and making the noise like I had a flat. I parked her on the side of the road and my buddy immediately called his dad, who knows way more about cars than us teenagers. He came down, checked the car out, and announced that it was a (now I can't remember exactly what he said but I'll try) "U" joint and I should get the car told, because there's no telling how long the car is going to be able to run, even at low speeds, before my driveshaft falls out. I'm sure hoping it's not my driveshaft, what am I going to need to do to get my car runnin smooth again?
