MACEL Front Wheel Hub Bearing Assembly 513188 for 2002–2009 Chevy/GMC SUVs, 6‑Lug w/ ABS, OE Fit

The MACEL 513188 is a direct-fit front wheel hub bearing assembly with ABS connector designed to replace worn hubs on select 2002–2009 GM and related SUVs.

This replacement hub assembly restores smooth wheel rotation, ABS sensor connectivity, and secure wheel mounting for vehicles originally equipped with a 6-lug hub pattern. Engineered to the original equipment (OE) bolt pattern and sensor interface, the MACEL 513188 is intended as a straightforward bolt-on solution for technicians and DIYers tackling common hub failures such as grinding, noise, or an illuminated ABS light.

Which vehicles will this hub assembly fit?

The 513188 has been manufactured to match OE fitment across a range of GM-platform SUVs and related models. Confirm fitment by matching part numbers and vehicle year/model before purchase.

• Compatible models include Chevy Trailblazer (2002–2009) and Trailblazer EXT (2002–2006)
• Fits GMC Envoy (2002–2009), Envoy XL, and Envoy XUV years listed
• Also fits 2003–2006 Chevy SSR, 2003–2007 Isuzu Ascender, 2004–2007 Buick Rainier, 2005–2009 Saab 9-7X, and select Oldsmobile Bravada years
• Replaces OEM numbers and matches the 6-lug configuration with ABS wheel speed sensor connector

How does this assembly match OE specifications?

MACEL engineered the 513188 to the critical dimensions and interfaces found on original equipment hubs so it installs without modification. That includes identical bolt pattern, hub spline, wheel flange, and ABS sensor connector geometry.

• Direct-fit bolt pattern and wheel flange for bolt-on installation
• OEM-style ABS speed sensor connector for plug-and-play electrical compatibility
• Hub spline and dimensions machined to match factory tolerances
• No cutting, welding, or special adapters required

What materials and design features improve durability and performance?

The hub assembly uses hardened bearing steel and protective coatings to resist wear and environmental exposure common on road-driven SUVs. Bearings and grease are selected to reduce friction, noise, and vibration during operation.

• Forged GCr15 bearing steel, heat-treated for load strength
• Anti-rust housing coating to resist salt and moisture corrosion
• ABEC-5 precision bearings and high-temperature grease for quieter rolling
• Quality control testing: dynamic load, run-out, and salt-spray inspection

What symptoms will replacing this hub assembly address?

Swapping in a new MACEL hub assembly can correct mechanical and ABS-related faults caused by worn bearings or damaged hub components. It restores secure wheel mounting and predictable ABS signaling.

• Remediates grinding, humming, or rumbling noises from the wheel area
• Eliminates wheel wobble or looseness due to worn bearings
• Resolves intermittent or constant ABS warning lights tied to wheel speed failure
• Improves steering feel and smoothness at speed

Who is this for? The MACEL 513188 hub assembly is aimed at professional technicians, independent repair shops, and experienced DIYers who need an OE-style replacement for 6-lug front hubs on compatible GM-platform SUVs. It suits customers who want a direct-fit part with corrosion protection and tested bearing components, plus reliable ABS connector compatibility for vehicles listed in the fitment section. Always verify vehicle year, axle side, and OEM part number before ordering to ensure correct fitment.
