Frequently Asked Questions

Does installing this axle affect my factory warranty?
Under the Magnuson-Moss Warranty Act, the manufacturer must prove the aftermarket part caused the specific failure before denying warranty coverage. Installing a stronger axle shaft does not automatically void your warranty.

What is the difference between YA F880039 and YA F880038?
These two part numbers cover the right and left rear axle shafts respectively for the 2003 and newer Ford 8.8 inch Crown Victoria with ABS. YA F880039 is the right side shaft. Order both for a complete pair replacement.

Does this shaft come with the ABS ring?
Yes. YA F880039 includes the ABS reluctor ring already installed on the shaft, ensuring correct ABS sensor operation without any additional parts or machining.

What is 1541H alloy steel?
1541H is a microalloy steel with a higher manganese content than standard 1040 carbon steel. It provides improved tensile strength, toughness, and heat treatability, resulting in a more durable axle shaft with better fatigue life.

Is YA F880039 compatible with aftermarket wheels?
Yes. The shaft flange uses the stock Ford Crown Victoria 5x4.5 inch bolt pattern and is compatible with any wheel using that pattern and the correct center bore dimension.

Does this axle work with both drum and disc rear brake Crown Victorias?
YA F880039 is designed for the disc brake 8.8 inch rear differential configuration used in 2003 and newer Crown Victoria models. Confirm your specific brake configuration before ordering.

Can I install YA F880039 myself?
Yes. With basic hand tools and a floor jack, a C-clip axle shaft replacement is manageable for an experienced DIY mechanic. The differential must be opened to remove the C-clip.

Do I need new bearings when installing YA F880039?
It is recommended to inspect the axle bearing and seal when replacing the shaft. If the bearing shows any roughness or the seal leaks, replace both while the differential is open.

What warranty does YA F880039 carry?
Yukon Gear provides a manufacturer limited warranty against defects in materials and workmanship from the date of purchase.

Installation Instructions

2. Remove the brake caliper and rotor to expose the axle shaft area.
3. Remove the differential cover, drain the gear oil, and remove the pinion shaft lock bolt and pinion shaft.
4. Push the axle shaft inward toward the differential to expose the C-clip on the shaft groove.
5. Remove the C-clip with needle-nose pliers and slide the axle shaft out of the axle tube.
6. Apply a light coat of clean gear oil to the spline end of the new axle shaft.
7. Slide the new shaft into the axle tube, engaging the splines with the differential side gear.
8. Install the C-clip into the shaft groove. Pull the shaft outward to seat the clip against the side gear.
9. Reinstall the pinion shaft and torque the lock bolt to factory specification.
10. Clean the differential cover mating surface and reinstall with new RTV sealant. Fill with correct gear oil.
11. Reinstall the rotor, caliper, wheel, and tire. Torque all fasteners to specification.
12. Road-test and inspect for leaks after 50 miles.
