Ford Expedition Axle Shafts & Parts

The axle shafts of a vehicle are responsible for transferring torque from the differential or transaxle to the drive wheels. Meanwhile, their design depends not only on the expected torque but also on the suspension type. The first-gen Ford Expedition came with a solid rear 8.8 axle, but more modern versions received an independent rear suspension (IRS) with two CV axle shafts. The independent setup offers better ride quality and improved traction, however, the live axle also has something to boast of. Commonly, it's considered stronger than the IRS and needs less maintenance. A solid axle also consists of two sections but they are covered with a metal housing and don't utilize CV joints.

Thanks to this, the live axle has fewer moving parts that could create troubles. But still, whatever setup you have, it may need your attention. The weakest parts in a CV axle are rubber boots protecting the assembly from dirt and water and containing a fairly large amount of grease. It's crucial not to miss the time when any of these boots crack, and visual inspection is very useful in this regard. As for a solid axle, potential issues are mainly related to the wheel bearings. In our online store, you will find a wide range of Ford Expedition axles and other components for different generations of this vehicle.
