Remove the lock rings from the front yoke trunnion bearings and drive out the bearings. This separates the front yoke from the spider and the universal joint is now completely disassembled.
Layout of Parts of Front Propeller Shaft Assembly
Remove the snap ring holding the ball bearing in the front propeller shaft housing with a pair of pliers. Remove the shaft and bearing assembly from the housing. Press the ball bearing from the shaft.
If it is necessary to replace the bushing pressed into the front
propeller shaft housing, the dowel that holds it in place should
be drilled out and the bushing driven from the housing.
In replacing this bushing, it is driven into position and a hole
drilled in the bushing to match the hole in the housing, deep enough
to take a new dowel. The dowel is then driven into place and prick
punched around the edge of the hole in the housing, to keep it
in place and also keep the bushing from turning.
In assembling the front propeller shaft assembly, check fit between
universal joint ball sleeve and propeller shaft housing, replacing
ball housing if necessary. Assemble universal housing, less shafts,
first removing cork gaskets, then removing or adding shims between
the retainers so that the proper amount of tension is obtained
to maintain proper alignment and oil seal.
Install new cork gaskets, shellacing them in the ball retainers,
coat the ball and cork gaskets with graphite grease — this
will give the proper lubrication and prevent wear on the cork gaskets.
Check and if necessary replace the seal in the end of the joint
ball housing sleeves. The balance of the assembly operations are
just the reverse of the disassembly operations, except that the
front propeller shaft should be filled with a generous supply of
lubricant, SAE No. 160, after it has been assembled back on the
truck.
