The short version
- A 2004 Lincoln Aviator wheel bearing order is simple: one front hub, 515050, and a rear press in bearing, 516008, across all three model years.
- Front hub 515050 covers both drivetrains offered on the Aviator, all three years, 2003 through 2005.
- The rear uses a press in bearing, 516008, on this full size SUV rather than a bolted hub.
- A separate rear hub repair kit, 521000, exists alongside the rear bearing listing.
Lincoln built the Aviator for only three model years, 2003 through 2005. The wheel bearing lineup stayed just as short and stable.

This page covers the 2003-2005 Lincoln Aviator: 2003, 2004, 2005. Other years live on the main Aviator wheel bearing page.
The rear bearing is a press in unit on a full size SUV, which is less common than a bolted hub assembly at that end.
A separate rear hub repair kit, 521000, also exists. It is not the same listing as the bearing itself.
The 516 and 521 prefixes look unusual next to the more common 513 and 515 numbers, but they are correct rear specific listings, not typos.
Year by year
2003, 2004, and 2005 share every row on this page. Nothing changes across the Aviator’s whole production run.
A 2004 Lincoln Aviator wheel bearing order reads the same as a 2003 or 2005 order.
The front hub, the rear bearing, and the rear repair kit all apply equally to every year.
A short run with one part list
The Aviator sold for just three years, so this page and the model page cover the same ground.
The rear press in design is worth understanding before ordering. Read press in wheel bearing basics first if this job is new to you.
The short production run means the same 2004 Lincoln Aviator wheel bearing numbers apply no matter which of the three model years shows up on the title.
Diagnosing a Lincoln Aviator wheel bearing
- Listen for a rotating hum. A bad bearing typically hums or growls and gets louder with speed. See wheel bearing noise on turns for how it shifts in corners.
- Check for play at the wheel. Raise the SUV, grab the tire at 12 and 6 o’clock, and rock it to feel for looseness.
- Decide bearing versus hub kit. If the bearing race itself is worn, 516008 is the fix. If the hub carrier is damaged, look at the 521000 repair kit instead.
- Rule out tire wear. Cupped tires can sound like a bearing. Compare against tire noise or wheel bearing before ordering parts.
- Watch the ABS light. A failing rear hub sensor can trip the light before the noise is obvious. See bad bearing and the ABS light for that pattern.
