Page 42 3 - 2 PROPELLER SHAFTS DESCRIPTION AND OPERATION (Continued) Before undercoating a vehicle, the propeller shaft and the U-joints should be covered to pre- vent an out-of-balance condition and driveline vibration. CAUTION: Use original equipment replacement parts for attaching the propeller shafts. The speci- fied torque must always be applied when tightening the fasteners.
Page 43 PROPELLER SHAFTS 3 - 3 DESCRIPTION AND OPERATION (Continued) PROPELLER SHAFT JOINT ANGLE DESCRIPTION When two shafts come together at a common joint, the bend that is formed is called the operating angle. The larger the angle, the larger the amount of angu- lar acceleration and deceleration of the joint.
Page 44: Brakes
3 - 4 PROPELLER SHAFTS DESCRIPTION AND OPERATION (Continued) Propeller shaft speed (rpm) is the main factor in DIAGNOSIS AND TESTING determining the maximum allowable operating angle. As a guide to the maximum normal operating angles VIBRATION refer to (Fig. 5). Tires that are out-of-round, or wheels that are unbalanced, will cause a low frequency vibration.
Page 45 PROPELLER SHAFTS 3 - 5 DIAGNOSIS AND TESTING (Continued) UNBALANCE NOTE: Removing and re-indexing the propeller shaft 180° relative to the yoke may eliminate some vibrations. If propeller shaft is suspected of being unbalanced, it can be verified with the following procedure: (1) Raise the vehicle.

If the clearance varies, it may be caused by either a tapered journal, bent connecting rod or foreign material trapped between the insert and cap or rod.
Page 998 2.5L ENGINE 9 - 23 SERVICE PROCEDURES (Continued) (11) FOR EXAMPLE: If the initial clearance was 0.0762 mm (0.003 inch), 0.025 mm (0.001 inch) undersize inserts would reduce the clearance by 0.025 mm (0.001 inch). The clearance would be 0.002 inch and within specification.
