Installing wheel bearing races can be a chore. Installing them without damage to the bearing race or the surrounding components is easy if you have the correct tool. The Powerbuilt Adjustable Bearing Race and Seal Tool is an innovative tool that allows you to install different sized wheel bearing races with one tool without damaging them. Get rid of the guessing game hunting through multiple adapters by using a single tool with its unique cam design. The cam design allows it to adjust to an enormously vast range of bearing race and seal diameters to fit most foreign and domestic vehicles. Simply rotate the knurled collar on the neck of the unit and the aluminum installer surface will open close easily adjusting to the exact diameter needed for your application, eliminating the need for separate drivers and components. All Powerbuilt kits meet or exceed ANSI and/or ASME standards assuring a lifetime of use. Includes a heavy-duty carry case with usage photos and Detailed instructions.
