I concur with tcdermam and to add,
Make sure all mating surfaces are thoroughly cleaned and the bolts are torqued to specifications.

The four Universal Joint Ball (Housing) collar bolts, 8-12 ft. lbs. Torque.
The four Universal Joint bolts or cap screws, 25-30 ft.lbs. Torque read under assembly
The one Universal Joint front yoke attaching bolt, 15-20 ft. lbs. Torque

Don't forget the two U-Joint bolts/cap screws lock plates.

Note: The Universal Joint Ball (Housing) collar on the 1/2 ton trucks & Passenger cars equipped with Hydra-Matic / Powerglide transmissions use six bolts.
There is no change in torque spec
