Expedition 4WD V8-4.6L SOHC VIN 6 (1997)
Drive/Propeller Shaft: Description and Operation
The driveshaft is a tubular shaft which transfers torque from the engine, through the transmission to the rear axle. Driveshafts differ in length, diameter,
and type of slip yoke to accommodate various wheelbase and powertrain combinations.
The rear driveshaft is connected to the driveshaft rear axle companion flange by a driveshaft flange yoke with four bolts. It is connected to the transfer
case with a driveshaft slip yoke.
NOTE:
-
Whenever the vehicle is raised on a hoist, inspect the slip yoke seal for damage. Replace if required.
-
All front driveshafts are balanced. If undercoating the vehicle, protect the driveshaft and universal joints to prevent application of any
undercoating material.
The front driveshaft is connected to the transfer case and the front drive axle by the driveshaft flange yoke.
