How will replacing worn hubs with KNOLET parts affect driving and maintenance?

Replacing degraded or noisy bearings and hubs helps eliminate wheel rattling, reduces steering or wheel vibration, and stops grease leakage that can damage other components. KNOLET hubs use a premium sealing design and protective coating to resist moisture and reduce long-term wear, lowering the chance of repeat service in the near term.

• Reduced noise and vibration at the wheel end
• Improved ABS wheel-speed signal reliability
• Corrosion-resistant coating and premium seals for longer life
• Precision manufactured to OEM-style tolerances for easier installation

What should I know about installation and professional fit?

These hubs are intended as direct-replacement assemblies for compatible vehicles, which simplifies installation but still requires proper tools and torque procedures. Because the hubs include ABS encoders and precise pilot dimensions, correct installation ensures accurate wheel alignment and ABS functionality. If you’re not confident in hub replacement, have a professional mechanic complete the job to ensure safety-critical torque and bearing preload settings are met.

• Designed for straightforward, OE-style installation
• Requires correct torque and bearing preload where applicable
• ABS encoder must be connected and checked for proper signal
• Professional installation recommended if unsure about procedures

Who is this for: KNOLET 513289 wheel hub assemblies are a practical option for owners and mechanics working on Cadillac SRX (2010–2016 model years, depending on position) and Saab 9-4X 2011 vehicles who need a reliable, OE-dimensioned replacement with an integrated ABS encoder. Choose these hubs if you want corrosion resistance, factory-style fit, and the convenience of a ready-to-install hub assembly designed to restore wheel stability and ABS performance.
