To replace the Universal Joint with an external snap ring, first, you should lay the propeller shaft on the press table horizontally so as not to damage the tubing by clamping it in a vice. Tag the propeller shaft to show the transmission and rear axle connections. Disassemble using pliers the snap rings and, if needed, tap the cup end lightly to relieve pressure. Start the support of the lower ear of the yoke onto 30 mm (1-1/8 in) hex head socket or onto 27 mm (1-1/16 in) socket and then to place j 9522-3 onto the open horizontal bearing cups in order to press the lower bearing cup out of the yoke ear. If the bearing cup fails to come out all the way, raise the cross and place j 9522-5 in between the seal and bearing cup to keep pressing it out. Rotate the propeller shaft to drive out the opposite bearing cup and note the orientation of Slip Yoke to tube that one therefore needs for reassembling. Remove the cross & other universal junt event as well and in the case of changing the front Universal Joint, take off bearing cups found on the Slip Yoke as well. Check retaining ring groove and bearing cup bore for cleanliness and imperfections and cleaning where necessary. For assembly, take bearings cups off from the Universal Joint and have one of the bearings cups half assembled into the one end of the yoke while the yoke ear is pointing down. Place the cross on the ends of the trunnion such that the trunnion fits freely in the bearing cup and push the bearing cup into the yoke until its flush with the yoke. Mount one of the opposite bearing cups partially inside a yoke ear making sure that the trunnions are pointing straight into the bearing cups. Press the contrary bearing cup as you check for the free movement of trunnions; if there is binding, check the needle bearings for misalignment. Press further applying pressure, up until you see the bearing cup retainer groove, then install the bearing retainer into the groove and press everything until both retainers snap into place. If fitting the retainer becomes difficult than a firm hammer blow from the kind of dead hammer (which is intended for such blow on snap ring) can help, and a little of the chassis grease can help paint the grease on the snap ring to smooth the entry.
