^
Tools Required
-

J 9522-3 U-Joint Bearing Separator

NOTICE: Never clamp propeller shaft tubing in a vise. Clamping propeller shaft tubing in a vise could dent or deform the tube causing an imbalance
or unsafe condition. Always clamp on one of the yokes and support the shaft horizontally. Avoid damaging the slip yoke sealing surface. Nicks may
damage the bushing or cut the lip seal.
NOTICE: The flange yoke can be replaced without removing bearing cups from the tube yoke or ball support yoke.
1. Remove the bearing cups in the order indicated (1-4). This is the shortest route to the heart of the centering ball system. Make a close inspection in
order to select the correct service method.
2. Mark all the yokes before disassembly in order to reassemble the yokes, and in order to retain the driveshaft balance.
IMPORTANT: You can not reassemble production universal joints. There are no bearing retainer grooves in production bearing cups. Discard
all universal joint parts you remove.
3. Support the propeller shaft in a line horizontal with the table of a press.
