Got my daughter's Jeep running very nice but for one thing . At about 100 k , there is a shudder comes into the vehicle and then leaves again . It feels like a bad carrier bearing on drive shaft but the Jeep doesn't have one.
Anyone got any idea what could make the jeep shudder like that ? I'll make a guess and say its the converter. It happens sporadically just for a second but it is intense. Scared the life out of my daughter the first time it happened.
Any guesses?

Check front prop shaft carefuly .The rear CV style joint in particilal.
