The short version
- A Blazer wheel bearing search often turns up 513188, but that number belongs to the TrailBlazer, not the 1998 to 2004 S-10 Blazer.
- The S-10 Blazer front splits by drivetrain. 513200 covers two wheel drive, and 513124 covers four wheel drive.
- The rear is a solid axle. It splits three ways, by axle code and by the ZR2 off road package.
- The Blazer name covers more than one vehicle, so establishing the exact truck matters before ordering anything.
This name has been used on several different vehicles over the years. The 1998 to 2004 S-10 Blazer is the compact truck this page covers.
A widely cited number for this page, 513188, is actually TrailBlazer data. That is a separate, larger truck built on its own platform.
The real S-10 Blazer numbers split by drivetrain at the front and by axle code at the rear.
Which Blazer do you have
It has been used on a full size truck, this compact S-10 truck, and later the unrelated TrailBlazer and a modern crossover.
Those are entirely different vehicles with entirely different hubs. The year alone will not sort them.
This page covers the compact S-10 Blazer, built 1998 to 2004. Establish the era first, before reading any number below.
The full size Blazer ended production before the compact truck’s own run began, so there is no overlap to confuse there. The TrailBlazer arrived after the compact truck stopped, which is where the real confusion starts.
The old TrailBlazer number does not belong here
That number is cited for the Chevrolet TrailBlazer, the GMC Envoy, the Buick Rainier, the Saab 9-7x and the Isuzu Ascender.
All five are a completely different General Motors platform, built years after the S-10 Blazer ended production.
The S-10 Blazer’s real front numbers are documented separately below, split by drivetrain rather than shared across those badges. The TrailBlazer keeps its own coverage on its own page.

Lookups run through the cross reference page.
Every model year this chart resolves: 1998, 1999, 2000, 2001, 2002, 2003 and 2004.
The rear position splits three ways within the same model year: standard axle code C, standard axle code K, and the ZR2 wide stance package.
A limited slip differential adds a fourth variant for 1999 to 2001. Check the tag on the axle housing before ordering a seal.
Front splits by drivetrain, not by trim
513200 covers the two wheel drive front, excluding the ZR2 package. 513124 covers the four wheel drive front instead.
Both are documented across the full 1998 to 2004 span, and three separate catalogs corroborate the same drivetrain split.
A sensor kit ships separately from the two wheel drive hub in one parallel listing. Check whether the kit is included before assuming one box covers the whole job.
Four wheel drive trims use a different hub entirely, 513124, with its own seal cited separately at 3553. That seal is documented across a wider span than the hub itself, 1995 to 2005 in one parallel listing, so a seal alone can be sourced even where the full hub assembly is not.
The rear axle splits three ways
The rear splits by axle code, C or K, each with its own seal despite sharing the same cylindrical bearing.
The ZR2 and Wide Stance off road package adds a third, wider bearing entirely, 6408 rather than 5707.
The difference between this kind of axle bearing and a bolt on hub is covered on the axle bearing page.
Failure on a solid rear axle tends to announce itself as a low hum that rises with speed, similar to the front, but the fix means opening the axle housing rather than four bolts on a knuckle. That distinction is worth knowing before a shop quotes the job, covered generally on the failure page.
The sensor inside the hub
The wheel speed sensor is built into the front hub on this generation. It can fail independently of the bearing itself.
An ABS light with no noise and no play usually means the sensor. The fix is still the same hub unit either way.
Rule out a simple connector fault first. It costs nothing to check before ordering a hub.
Diagnosing a Blazer wheel bearing
- Confirm the platform, since this page covers the 1998 to 2004 compact truck only.
- Check the drivetrain before ordering a front hub.
- Read the axle tag before ordering a rear seal.
- Check for an ABS light, since the sensor lives in the front hub.
- Weave at road speed and note which side loads the noise.
Those checks are on the checking page and the tire noise page.

Common questions
Which Blazer wheel bearing do I need?
Start with the drivetrain at the front, 513200 for two wheel drive or 513124 for four wheel drive. The rear depends on the axle code.
Is 513188 the right number for my Blazer?
No. That number belongs to the TrailBlazer and its badge mates, a different platform built later.
How do I know my rear axle code?
Check the tag on the axle housing. The code decides the seal even when the bearing itself stays the same.
ABS light but no noise?
That points at the speed sensor inside the front hub rather than the bearing.
Do I need a press for the front?
No. The front is a bolt on hub assembly on both drivetrains.
