2. Position the joint in an open vise, with each ear
of the yoke supported by a vise jaw. With a soft
hammer or mallet, strike the top ear of the
unsupported yoke at 1. This will drive the top
bearing outward approximately 8 mm (1/4I).
IMPORTANT: Do not use a hard faced hammer, as
this may damage the edge of the bearing cup bore in
the yoke, causing the bearing cup to hang up or seize
in the yoke.
3. Pull the bearing, 2, out of the yoke ear. If
necessary, grip the loosened bearing in a vise,
and drive the yoke off the bearing by striking the
yoke ear with the soft faced hammer or mallet.
4. Repeat this procedure to remove the bearing
directly opposite the one just removed. Rotate
the yoke from the cross.

5. Support the cross in a vise, making certain the
vise jaws are covered with brass protectors or the
previously removed bearing are reinstalled on

U-JOINT ASSEMBLY
1. Position the cross in the yoke so that the bearing
journals are in each yoke ear. Insert the bearings
in the outside of the yoke ears, and position the
assembly is a vise. Press the bearings in until
they are flush with the edge of the yoke.
2. Using a socket, 1, of the same diameter as the
bearing, press the bearing into the yoke ear until
the snap ring groove is exposed on the inside of
the yoke ear. Install the snap ring over the
bearing cup.
3. Reposition the yoke and cross in the vise, and
use the socket to press the opposite bearing fully
into the yoke ear while rotating the cross to
ensure it does not bind. Continue to press the
bearing into the yoke ear until the snap ring can
be installed. It may be necessary to push the
bearing in as far as possible with the vise, and
then remove the yoke assembly and strike the
yoke ears with a sharp blow from a hammer to
spring the yoke enough to install the snap ring.
