if it is a U -joint you would feel and hear a clunking noise. I would suspect you feel normal rear axle play. If the jerking was at steady throttle while driving, I would suspect fuel and or ignition problems, bad fuel... do you have high mileage like 50,000 plus? if so maybe change the spark plugs, dirty air filter..
