Autoround Front Wheel Bearing Hub Assembly 2-Pack — 6-Lug w/ABS, Direct-Fit Replacement

Autoround 513188 is a direct-fit front wheel bearing hub assembly (2-pack) designed to replace worn hubs on select Chevy, GMC, Buick, Saab and Isuzu SUVs and pickups with 6-lug wheels and ABS.

When a wheel hub or bearing shows noise, looseness, or ABS sensor warnings, swapping in a properly specified hub assembly restores safe wheel mounting and ABS function. The Autoround 513188 assemblies are built to match OE fitment for the listed vehicles and come as a pair so both front hubs can be refreshed at the same time for balanced performance.

Which vehicles and part numbers does this hub assembly fit?

This 513188 hub is compatible with multiple GM-platform SUVs and the Isuzu Ascender and Saab 9-7x that share the same front hub design. It replaces many OE references so mechanics can cross-check fit before ordering.

• Fitment includes: 2003–2006 Chevy SSR; 2002–2009 Chevy Trailblazer and 2002–2006 Trailblazer EXT;
• 2002–2009 GMC Envoy, 2002–2006 Envoy XL, 2004–2005 Envoy XUV;
• 2004–2007 Buick Rainier, Isuzu Ascender, Oldsmobile Bravada, Saab 9-7x where applicable;
• OE cross references: 513188, 8151308580, H513188, BR930470, 12413037 and similar numbers for verification.

How does the 513188 assembly handle ABS and wheel mounting needs?

The assembly includes an integrated wheel bearing and tone ring compatible with ABS systems used on the covered models. That means the hub provides the sensor reference surface required for correct ABS readings and secure 6-lug wheel mounting.

• Integrated ABS-compatible tone ring for sensor signal consistency;
• 6-lug flange to match factory wheel bolt pattern and torque specs;
• Flange diameter 5.92 inches and flange offset 1.85 inches for accurate wheel positioning.

What are the build quality and installation expectations?

Autoround wheel bearing and hub assemblies are manufactured and tested to meet or exceed common OEM performance criteria. The units come pre-assembled so installation is faster than pressing in a separate bearing and race, and they simplify front-end service.

• Pre-assembled hub and bearing for quicker replacement and fewer tools;
• Precision-machined mounting surfaces to ensure proper fit and wheel alignment;
• Manufacturer-backed QA and a three-year quality assurance period for buyer support.

What practical details should I check before ordering?

Confirm your vehicle’s year, model, axle side, and wheel lug count, and compare current part numbers to the listed cross-references. Also verify ABS tone ring presence and flange measurements if your vehicle has non-standard wheels or aftermarket modifications.

• Verify 6-lug configuration and ABS requirement on your vehicle;
• Match OE part number or compare flange diameter (5.92 in) and offset (1.85 in);
• Inspect hub mounting surface and axle stub for compatibility before installation.

Who this is for: technicians, DIY mechanics, and owners of compatible Chevy, GMC, Buick, Saab and Isuzu vehicles who need a direct-fit front hub replacement with ABS compatibility. Choose the Autoround 513188 2-pack when you want pre-assembled hubs that simplify front-end repair and help ensure both sides are refreshed together for consistent wheel handling and brake-sensor performance.
