Ford Expedition Driveshafts & Parts

A driveshaft is a crucial part of any front-engined rear-wheel-drive vehicle, which connects the gearbox and rear differential to transfer engine torque. However, if your Ford Expedition has a 4WD system, its driveline configuration is somewhat different. Actually, the vehicle has two driveshafts, the front and rear one. The latter is still responsible for driving the rear wheels, while the former delivers horsepower to the front axle by connecting the transfer case and front differential. Both front and rear differentials have either CV - or U-joints, and their servicing varies depending on the joint type.

The common signs of a faulty U-joint are vibration at different speeds, clicking noise when the vehicle slowly backs up, and clunking sound when a gear is shifted from reverse to drive. Many modern vehicles have a driveshaft with non-replaceable U-joints, while some aftermarket shafts allow for replacing these joints or lube them using a special grease fitting. As for CV joints, they are normally covered with a rubber boot filled with grease; in general, they are better protected from water and dirt unless the boot is damaged. Whatever configuration your SUV has, you will be able to maintain or restore it using quality products from our Ford Expedition driveshafts inventory.
