High-quality KNOLET 513288 wheel hub bearing assembly engineered to restore wheel stability and smooth rotation on compatible Chevy, Cadillac, Buick, GMC and Saab vehicles.

If your vehicle shows wheel noise, vibration, or uneven steering feel, the hub bearing is a common wear item that can cause those symptoms. The KNOLET 513288 assembly is built to match OE-style dimensions and fit a wide range of models — including Chevrolet Malibu and Impala, Cadillac CTS and XTS, Buick LaCrosse and Regal, GMC Terrain, and select Saab and Equinox years — providing a direct-replacement solution that simplifies repair.

Which vehicles and model years does this hub fit?

The 513288 hub is designed as a direct-fit replacement for numerous GM-platform cars and crossovers. It covers specific years of Chevrolet, Cadillac, Buick, GMC, Saab and others; always use the vehicle selector or fitment list to confirm compatibility before ordering.

• Chevrolet: Malibu 2013–2015, Malibu Limited 2016, Impala 2014–2017, 2020, Equinox 2010–2017
• Cadillac: XTS 2013–2017, CTS 2014–2016

• GMC Terrain 2010–2017 and Saab 9-5 2010–2011 (verify OEM cross-reference numbers)

What are the key specifications and features of the 513288 assembly?

This hub assembly is manufactured from high-hardness forged carbon steel and precision-tested to match OEM fit and function. It includes a sealed bearing pack and five wheel studs, engineered for reduced friction and lasting service life.

• Position: front left or right axle (same part fits either side)
• Flange diameter: 6.18"; bolt circle: 4.72"; hub pilot: 3.59"
• Flange bolt holes: 3; wheel studs: 5; brake pilot: 2.95"
• ABS sensor: not included — compatible with vehicles that use separate ABS sensors

How does this replacement help with noise, vibration, or steering issues?

Worn bearings commonly produce grinding, rumbling, or play in the wheel/steering system. Replacing the hub with a precision assembly like the KNOLET 513288 restores proper wheel alignment and rotational smoothness, reducing noise and steering shimmy when installed correctly.

• Precision manufacturing minimizes runout and friction for quieter operation
• Premium seals prevent contamination and retain lubricant longer
• Protective coatings resist corrosion for longer service life in wet conditions

Is installation straightforward and what should technicians expect?

The 513288 is an OE-style hub assembly designed for drop-in replacement to reduce installation time. Most mechanics can replace it with common shop tools; wheel studs and the hub flange arrive assembled for a cleaner, faster install.

• Comes ready with wheel studs; no separate press-in bearing step required for many applications
• OE-dimension compliance helps ensure correct rotor mounting and wheel fitment
• Check vehicle-specific instructions for torque values and any ABS sensor reinstallation

Who is this for: The KNOLET 513288 hub bearing assembly is intended for DIYers, independent mechanics, and fleet technicians replacing worn front wheel hubs on compatible GM and Saab vehicles. It suits owners who need an OE-dimension replacement that balances durability, corrosion protection, and straightforward installation.
