Rear Driveshaft Cross and Bearing Service
1. Remove driveshaft from vehicle (see Rear Drive-
shaft in this section).
IMPORTANT: When placing yoke in vise, clamp
lightly on the solid part of the yoke to prevent yoke
damage. Also, the use of a vise with soft jaws is rec-
ommended.
2. Lightly clamp yoke in vise. Remove snap rings that
secure bearings at the inside of each yoke. Remove
yoke from vise.
IMPORTANT: Yokes must be supported when re-
moving and installing bearings to prevent damage.
3. Use a press to remove cross and bearings from
yokes:
A. Place a small socket against one bearing and a
large socket against the yoke on the opposite side.
B. While supporting the large socket, apply pressure
on small socket to partially push the opposite bearing
into the large socket.
C. Remove yoke from press, grasp partially re-
moved bearing and tap on yoke to completely re-
move the bearing.
D. Repeat process for remaining bearings.
E. Thoroughly clean and inspect all components.
4. To install new cross and bearings:
A. Apply a coating of grease to bearing bores of end
yoke (slip yoke or flange yoke) and driveshaft yoke.
Also, apply grease to bearings and seal of bearing
assembly. Make sure that all bearing rollers are prop-
erly seated in bearing cage.
B. Press one bearing partially into yoke.
IMPORTANT: Take care when installing cross
into bearing to avoid damaging bearing seal.

5. Lubricate grease fittings until grease purges from
bearing cups. Make sure to grease all cross fittings.
6. Make sure that assembled joint moves without bind-
ing. Slight binding can usually be eliminated by lightly
rapping the yoke lugs with a soft faced hammer. If bind-
ing continues, disassemble joint to identify source of
binding.
