4WD vs 2WD Hub — Same Vehicle, Different Parts
The 2003–2006 Ford Expedition and Lincoln Navigator are offered in both 2WD (RWD) and 4WD configurations. These use different front hub assemblies:
- 4WD variants — this listing (SA-515043): 515043, 6.87 kg, includes CV axle stub interface. Ford OEM: 6L1Z-1215BA.
- 2WD / RWD variants — see SA-515042: 515042, 6.34 kg, no CV axle interface. Replaces BR930457 / SP550206.
Installing the wrong hub for your drivetrain will result in incorrect fitment. Verify your drivetrain via VIN before ordering.
Ford OEM Cross-Reference — 6L1Z-1215BA
This hub assembly directly replaces Ford OEM part number 6L1Z-1215BA — the factory 4WD front hub specification for the 2003–2006 Ford Expedition and Lincoln Navigator on the UN93 platform. Ford and Lincoln owners can verify fitment by cross-referencing this OEM part number via their dealer parts system or Ford ETIS.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!
Marcus R.
Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.

I've bought aftermarket parts from many stores but AlchemyRide stands out for quality and value. The part was well-made, fit perfectly, and the price was very competitive. My BMW looks aggressive and clean — exactly what I wanted.

Excellent product and super easy to install. The gloss black finish matches my M Sport bumpers perfectly. Shipping was faster than expected and the part was well-packaged. Very happy with my purchase — my car looks completely transformed!
