Center Bearing

DESCRIPTION

Fig. 6:

The two-piece propeller shaft uses a center bearing to support the shafts. Two types of center bearings are used. Type 1 is used with the 9 1/4 axle. Type 2 is used with the Dana axles (Fig. 6). Both types are mounted in the same location.


OPERATION
The propeller shaft center bearing serves to divide the required propeller shaft length into two smaller shafts, which has several inherent advantages. Having two short propeller shafts instead of one long shaft decreases the chance of unwanted noise and vibrations. The shorter shafts are easier to balance and serve to increase ground clearance while maintaining acceptable driveline angles.
