U-Joints -- Inspection
NOTE: The U-joint cross and bearings must be
replaced anytime the U-joint is disassembled, even
if the cross and bearings were not the source of
failure.
1. Inspect the yoke ears, 1, for wear in the bearing
area; replace the yoke if there is any evidence of
wear, or if the bearing area is distorted. The
bearing cups must be a tight fit in the yoke ear.

2. On the CV U-joints, it is necessary to inspect the
intermediate connection between the yokes. On
the 50° CV U-joints, inspect the ball, 1, and
socket, 2, connection between the yokes for
excessive wear or galling. On the 80° CV U-joint,
inspect the conical bushings, 2, Figure 26, on the
yokes for wear or excessive play. Inspect the
intermediate plate, 3, Figure 26, for wear or
damage on the attaching pins, and excessive
wear between the plate and housing. Replace
components as necessary.
