1) Joints and connections
Check for any looseness of yoke flange connecting bolts
and center bearing retaining bolts.
G3M0019
2) Splines and bearing locations
Turn propeller shaft by hand to see if abnormal free play
exists at splines. Also move yokes to see if abnormal free
play exists at spiders and bearings.
G3M0020
3) Runout of propeller shaft
Turn rear wheels by hand to check for“runout”of propel-

rear propeller shaft tubes.
G3M0255
4) Center bearing free play
While holding propeller shaft near center bearing with your
hand, move it up and down, and left and right to check for
any abnormal bearing free play.
