Home › Vehicles › Ford › Ford Excursion Wheel Bearing Part Numbers
The short version
- Excursion wheel bearing numbers split three ways: 2WD front, 4WD front, and rear.
- 4WD front hubs split by wheel stud thread: coarse thread takes 515020, fine thread takes SP580205, the only such split on the site.
- 2WD front is a serviceable tapered setup: inner set SET47, outer cone 15101 and cup 15245, seal 4160.
- Rear is a full float axle: inner cone NP114036, inner cup NP064306, outer set SET38, seal 370247A.
Ford built the Excursion to out-size every SUV in its own lineup, a Super Duty frame wearing SUV bodywork. An Excursion wheel bearing job comes in three distinct flavors depending on axle and drive. Get the wrong one and the parts will not fit, no matter how close the numbers look.
The core Excursion wheel bearing split
Coarse thread studs take hub 515020. Fine thread studs take hub SP580205.
This is the only Excursion wheel bearing case on the site decided by stud thread instead of model year.

Lookups run through the cross reference page.
Coarse thread and fine thread hubs are not interchangeable, and nothing on the outside of the hub announces which one is fitted.
Count the threads or match the old part before assuming 515020 or SP580205 is correct.
A Super Duty in SUV clothing
The Excursion shared its platform with the Ford F250, a Super Duty truck in wagon clothing. That relationship explains why the front end splits into 2WD and 4WD listings instead of one universal number.
Ford also built a smaller diesel van on related hardware, the Ford Econoline. Its wheel bearing numbers are its own.
Nearly four tons on a full float rear axle
A loaded Excursion pushes close to four tons of vehicle weight. Ford answered that with a full float rear axle rather than a passenger car semi float design.
The rear bearings, NP114036 inner and SET38 outer, do not carry vehicle weight directly. The axle housing itself takes that load instead, the way a full float design is supposed to work.
Diagnosing an Excursion wheel bearing
The general method sits on the how to check a wheel bearing page. The steps below note where Excursion size changes things.
- Listen for a hum that builds with road speed. A worn bearing produces a steady drone that climbs with speed rather than engine RPM.
- Note which corner gets louder in a turn. A change in volume during a lock to lock sweep points at a specific corner. That pattern is covered on the noise in turns page.
- Check for play with the wheel jacked up. On a full size SUV this takes real leverage. Use a pry bar rather than hands alone at the rear.
- Rule out tire noise before condemning the bearing. A cupped tire can mimic bearing drone at highway speed, so compare against the tire noise checklist first.
- Confirm the stud thread and axle type before ordering parts. A 4WD front hub, a 2WD front hub, and a rear hub are three different jobs.
Common questions
How can the front hub thread type be confirmed on an Excursion?
Count the threads on the wheel studs or match the old hub before ordering. The catalogs give no year or trim rule, only the thread itself.
Does the 2WD Excursion wheel bearing setup differ from the 4WD front?
Yes. The 2WD front is a serviceable tapered design with seal 4160. The 4WD front instead uses a bolt-on hub split by stud thread.
What is different about the Excursion’s rear wheel bearing?
The rear uses a full float axle design. Inner cone is NP114036, inner cup is NP064306, outer set is SET38, and seal is 370247A. The axle housing carries the vehicle’s weight instead of the bearings.
Is the Excursion really the biggest SUV Ford ever built?
Yes. Ford built the Excursion from 2000 to 2005 as its largest SUV. That size came from a Super Duty frame shared with the F250.
What does a failing Excursion wheel bearing sound like?
Expect a low speed hum that grows louder with road speed and often changes volume in turns. Rocking a jacked wheel by hand for play, with real leverage on a truck this size, confirms it.
