Driveline - Vibration/Boom

Article No. 86-15-14 DRIVELINE VIBRATION/BOOM - TWO-PIECE DRIVELINES - NEW SYSTEM BALANCED SERVICE ASSEMBLIES


LIGHT TRUCK 1985-86 E150-350, F150-350

Noise, vibration and harshness concerns involving driveline vibration on 1985-86 E and F Series vehicles equipped with standard two-piece driveshaft may be improved by replacing the production unit with a new "System Balanced" driveshaft - coupling shaft assembly (4K145).

When replacing the driveshaft, be sure that the yellow dots on the driveshaft and axle companion flange are aligned. If the yellow dots are not visible, then the vehicle will have to be test driven to determine the best orientation.

PARTS: System balanced two-piece drivelines.
