Light-Duty Truck Yoke Puller for F-150 and 1500 Pickups

A yoke that has sat on its splines for 150,000 miles does not want to come off. The usual fix is a hammer and a pry bar, and that is how output shaft seals get torn, yoke ears get bent, and pinion bearings take a hit they did not need. This puller does the job with a forcing screw instead: two clamp blocks bolt across the yoke ears, the T-bar spans them, and the screw pushes against the end of the shaft until the yoke slides off straight.

It is sized for Class 1-2 light-duty trucks, including Ford F-150 and F-350, Chevrolet and GMC 1500 through 3500, and Ram 1500 through 3500. Use it on rear differential pinion yokes when you are replacing a pinion seal or setting pinion preload, and on transmission or transfer case output yokes when you are doing a rear seal or swapping a tailhousing.

On the bench or under the truck: pull the driveshaft, mark the yoke to the pinion if you plan to reuse it, and remove the pinion nut. Bolt the two blocks across the yoke ears, set the T-bar over them, and run the forcing screw in against the center of the shaft. Snug it, then turn it steadily with a wrench until the yoke breaks loose. Do not hit the screw; let the threads do the work. For heavy Class 6-8 yokes, use a heavy-duty puller instead.
