1.Mark the driveshaft

Mark the driveshaft orientation before beginning. This will help return the driveshaft to its original position on the differential which can help avoid driveline vibrations once the driveshaft is reinstalled.

2.Remove Driveshaft Bolts and Remove Driveshaft Flange

Remove the shaft differential flange mounting bolts. These bolts will be very tight so use good quality tools to avoid stripping. Some bolts can head 12 point heads as in this example which used a 13mm 12 point socket to remove. These bolts also use lock tight to avoid coming loose while in operation and can be reapplied when reinstalling. Using a plastic hammer gently shock the driveshaft lose from the differential flange by striking the rear yoke (U joint mount). At this point, the back half of the shaft will be free to hang onto it. On some cars, there will be a center support which must be undone by removing the two center support mounting bolts. When removing an older vehicle drive shaft use electrical tape to wrap around U-joint cups so they don’t fall off and release the cup needle bearings.

3.Remove Driveshaft

Using both hands gently slide the driveshaft from the transmission or transfer case. A small amount of fluid might leak out so have a fluid catch basin ready. This would be a good time to replace leaking transmission tail housing seal, universal joints or if removing the transmission or differential repairs are needed.

4.Check U joints and Bolts

At this point, the U joint at either end of the shaft should be checked. Grasp the yoke and move it in all directions. It should be a smooth motion with no rough spots or play in any direction. If a play or rough spots occur then the U joint needs to be replaced.

5.Reinstall Driveshaft and Reinstall Flange Bolts

 Before re-installing the driveshaft apply a small amount of grease to the yoke. This will help lubricate the output shaft seal in the transmission or transfer case. There is a dust boot along with the rear seal which is incorporated within the transmission or transfer case tail housing seal. This transmission or transfer case output shaft is where the driveshaft connects. Care must be taken when reinserting the driveshaft yoke as not to damage the seal. Gently guide the yoke into place over and onto the output shaft.Once the front yoke is installed pull the driveshaft back into place while inserting a mounting bolt by hand to avoid cross threading. Finish installing the mounting bolts while making sure the alignment marks are together. Tighten the bolts evenly and in a cross pattern to factory specs which is usually 55-65 foot-pounds of torque. If any fluid was lost during the job check and refill the transmission or transfer case after the shaft has been reinstalled and you are all set.
