Component Tests and General Diagnostics

Check the following points with propeller shaft installed in vehicle.

1. Joints and connections. Check for any looseness of yoke flange connecting bolts and center bearing retaining bolts.





2. Splines and bearing locations. Turn propeller shaft by hand to see if abnormal free play exists at splices. Also move yokes to see if abnormal free play exists at spiders and bearings.





3. Runout of propeller shaft. Turn rear wheels by hand to check for "runout" of propeller shaft.
Runout: Limit 0.6 mm (0.024 inch).

NOTE: Measure runout with a dial gauge at the center of front and rear propeller shaft tubes.





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.
