• Loose or rough rear wheel rotation from bearing wear

Installation Notes and Tips

Verify rear fitment by year, make, and model before installation. Inspect the mating surfaces, axle splines, and brake components for wear or corrosion before mounting the new hub assembly. Confirm the ABS connector and wheel speed sensor routing match the original configuration on the vehicle. For 2002-2007 Saturn Vue, 2006 Pontiac Torrent, and 2005 Chevrolet Equinox rear applications, follow factory torque specifications and service procedures during installation.
