The Pacific Automotive Industries Generation 1 On Car Wheel Bearing Removal and Replacement Tools, No. 20-00011, is designed to replace front or rear wheel bearings directly on vehicles, saving technicians time. According to the company, replacing the wheel bearings take 15 to 30 minutes while using the set. The tool allows access even when the steering knuckle has uneven surfaces or fragile brake shields, the company says. The tool can be used with one of the company's hydraulic Rams or a manual screw assembly (sold separately) and a 1/2" drive impact wrench.
