The short version
- The Grand Marquis wheel bearing chart splits by production date, matching the rest of the Panther platform.
- 1990 and 1991 models use a serviceable tapered set: SET11 inner, SET12 outer.
- From 1992 onward the front uses a sealed hub, numbered 513104, then 513202, then 513196, then 513230.
- The rear is a live axle. Match the old part by ring gear size.
Retirees kept this car in production long after the Crown Victoria felt dated, and the bearing chart proves it never changed underneath. Every front hub number tracks the same production dates used across the Panther family. The Marauder, with its tuned V8, uses the same wheel ends as the base sedan.
The hub numbers that matter most
This hub covers the newest Grand Marquis wheel bearing coverage, in service from February 2005 onward. Catalog rows for it run 2004 through 2009, and the Marauder is included in that range.
It replaced 513196, used from 2003 through early 2005. That split lands inside the 2005 model year, so match by production date rather than the year on the title.

The Marauder does not change this chart. Mercury bolted a tuned V8 and different gearing into the Marauder, but the wheel ends stayed stock Panther parts.
A Grand Marquis wheel bearing order for a Marauder uses the same numbers as any other 2004 through 2009 sedan. The production date still decides between 513196 and 513230 for cars near the early 2005 cutoff.
The same chart as the rest of the family
This car shares its front and rear bearing numbers with the Crown Victoria and the Town Car. All three rode the Panther platform and used common running gear at every corner. A parts counter that stocks one usually stocks all three.
A car built for high, steady mileage
Buyers who kept a Grand Marquis for a decade or more put on highway miles at a steady pace, not the stop-start abuse of a taxi. That gentler use often means a Grand Marquis wheel bearing lasts longer than the same part in a fleet car. Shoppers comparing the wider Mercury lineup will find this chart applies only to Panther-based models.
Diagnosing a Grand Marquis wheel bearing
- Listen for a hum that changes with speed. A worn Grand Marquis wheel bearing usually growls or hums. The pitch rises and falls with road speed, not engine RPM.
- Turn corner to corner. Bearing noise on this car often gets louder in one direction, a pattern covered on the cornering noise page.
- Check for play at the wheel. With the car raised, grip the tire at 12 and 6 o’clock and rock it. Any looseness needs a closer inspection.
- Separate axle noise from wheel bearing noise. The live rear axle has its own bearing wear pattern, detailed on the axle bearing page.
- Confirm with a road test. Drive at a steady speed on an empty road and note whether the sound changes with steering input or stays constant.
Common questions
Is the Grand Marquis wheel bearing the same part as the Crown Victoria’s?
Yes. Both share the Panther platform and the same production date splits for every hub number listed above.
Does the Marauder need a heavier duty bearing?
No. The engine and suspension tuning changed, but the wheel end hardware did not.
How do I know which hub my 2005 model needs?
Match the production date, not the model year. Cars built before the February cutoff use 513196, and cars built after use 513230.
What does the rear axle bearing need for a match?
Match the old part by ring gear size. Cone and cup sets are not interchangeable across different axle ratios.
Are 1990 and 1991 models harder to service?
They use serviceable tapered bearings rather than a sealed hub. That means periodic repacking and adjustment instead of a bolt-on swap.
