1. Using a soft drift, tap the outside of the bearing cup

assembly to loosen snap ring. Tap bearing only hard
enough to break assembly away from snap ring.
Remove snap ring from yoke. Turn joint over, tap
bearing away from snap ring, then remove opposite
snap ring.
Apply alignment marks (1) on the yokes of the
universal joint, then remove snap ring.

2. Set the yoke in the arbor press with a piece of tube

stock beneath it.
Place a solid plug on the upper bearing assembly
and press it through to release the lower bearing
assembly.

3. If the bearing assembly will not pull out by hand

after pressing, tap the base of the lug near the
bearing assembly to dislodge it.

4. To remove the opposite bearing, turn the yoke over

and straighten the spider in the open hole. Then
carefully press on the end of the spider so the
remaining bearing moves straight out of the bearing
spider hole. If the spider or bearing are cocked, the
bearing will score the walls of the spider hole and
ruin the yoke. 

5. Repeat this procedure on the remaining bearing to

remove the spider from the yoke.

6. Make sure of proper position for reinstallation by

applying setting marks, then remove spider .

Spider pin for wear 

Spider pin should be smooth and free from fretting or
galling. Visible signs of needle presence is normal, but
wear should not be felt.
