Driveshaft. Driveshaft has been replaced twice, and the fuel resevoir has been moved. Drive shafts have been lubricated 6 times. Issue is that the drive shaft slips and jerks causing the vehicle to jump during light acceleration from a stop, and or when the vehicle comes to a stop with light braking. Lubrication of drive shaft works for periods of 6000-8000 miles before has to be reapplied.

When leaving a stop sign or traffic light the vehicle hesitated and made a loud sound before the vehicle moved. The vehicle was taken to the dealer who determined that an updated driveshaft was needed.

2000 Ford Ranger when taking off from a stop truck sutters. Dealership has put two driveshafts in truck. Fixed problem for a month or two and then problem comes back. Also when idling across parking lot truck well slam into next higher gear.

At 50,000 miles, my Ford Ranger began experiencing a slipping transmission and failed to start. The problems were diagnosed as a failed gasket in the transmission, and a failed valve body part in the motor (which was fixed with an "update kit"). the dealer also indicated that the ball joints were beginning to fail, and a front pinion seal had begun to leak.

While in any gear, when you accelerate drive shaft klunks, as if it wants to catch up to speed of engine. Same with deaccelerate. Very unconfortable driving-shifting. Thanks mark
