The short version
- The front Mazda 626 wheel bearing switched design in 1993. A bearing assembly ran through 1992, then a ball bearing plus separate seal took over.
- The rear splits by whether the car has ABS. The ABS number itself changes again in 1998.
- Non-ABS rear cars use one number, 512119, across the entire 1993-2002 run.
- The MX-6 shares the 626’s 1993-1997 numbers. The MX-6 in turn shared its platform with the Ford Probe.
Mazda kept the 626 in production for over a decade. That is long enough for the Mazda 626 wheel bearing catalog to change at the front once and the rear twice. Anyone pulling a number off an old part needs to know which era they are looking at first.
The 626’s core numbers
From 1990 to 1992 the front used a bearing assembly, 513057, paired with seal 1932S. From 1993 onward Mazda switched to a ball bearing, 510010, with the same 1932S seal.
The rear depends on whether the car has ABS. Non-ABS cars use 512119 for the whole run, while ABS cars split further by year.

Rear bearings on the 626 first split by whether the car has ABS at all. Non-ABS cars use 512119 across the full 1993 to 2002 run, so that half is simple.
ABS cars are the trap. The number is 512118 from 1993 through 1997, then changes to 512186 for 1998 through 2002. A 1993 ABS number will not fit a 2000 car, or the reverse.
The MX-6 and Ford Probe connection
Mazda sold the MX-6 alongside the 626, using the same rear bearing numbers for the 1993 through 1997 span. The MX-6 shared its platform with the Ford Probe, a joint Mazda-Ford project built in the same plant.
None of that changes what fits a 626 specifically. Treat MX-6 and Probe numbers as background, not a substitute for the 626’s own listing.
A family sedan’s daily wear pattern
The 626 was Mazda’s midsize family sedan. Its bearings saw the mix of commuting and highway miles typical of that class. Mazda eventually replaced the nameplate with the Mazda6, which carries its own separate part numbers.
Buyers cross-shopping a used 626 against a compact Mazda Protege should not expect the wheel bearings to interchange. The two sit in different size and weight classes, even sharing a badge era.
Diagnosing a Mazda 626 wheel bearing
- Note whether the noise is speed dependent. A bearing hum rises and falls with road speed, not engine RPM.
- Check ABS behavior first. Since the rear number depends on ABS, confirm the car actually has it before ordering a rear part.
- Jack up the affected corner. With the wheel off the ground, rock it at 12 and 6 o’clock. Feel for play in the bearing itself.
- Spin the wheel by hand. Roughness or grinding while spinning free with the brakes released points at worn races.
- Match the old part before ordering. Read the number off the removed bearing or seal, then confirm it against the year and ABS status.
Common questions
What is the front Mazda 626 wheel bearing part number?
From 1990 to 1992 it is bearing assembly 513057 with seal 1932S. From 1993 to 2002 it changes to ball bearing 510010, still with seal 1932S.
Does the 626 wheel bearing number depend on ABS?
Only at the rear. Non-ABS cars use 512119 for the whole 1993 to 2002 run. ABS cars use 512118 through 1997 and 512186 from 1998 on.
Do MX-6 wheel bearings fit a 626?
The MX-6 uses the same rear numbers as the 626 for 1993 through 1997. Outside that window, match by year and ABS status instead of assuming they always align.
Is the 626 wheel bearing a sealed hub assembly?
No. The 626 uses a press-in bearing and separate seal at the front, not a bolt-on hub unit, which is typical for a car this old.
How do I know which year’s Mazda 626 wheel bearing I have?
Pull the old part and read the number stamped on it. Match that against the table above rather than guessing from the model year alone.
