FRONT DRIVELINE BALANCE EVALUATION AND CORRECTION
The truck should be driven and evaluated in the 4X2 mode with the front hubs locked to determine if driveline balance disturbances are present in the
80-113 km/h (50-70 mph) drive range. If a balance adjustment is required, proceed with the following driveline field balance procedure.
DRIVELINE FIELD BALANCE PROCEDURE
This procedure is equally effective for balancing front or rear drivelines. Because most trucks are more balance-sensitive at the axle end of the system, it
is usually best to start there, then correct at the transmission/transfer case if necessary.
CAUTION:
THE TIRES AND WHEELS MUST BE BALANCED BEFORE ADDRESSING OR FINE TUNING THE DRIVESHAFT.
