Hi, These parts are for all 4 wheels (front and rear). The bearings are already pressed into the hubs, no need to worry about that. For accuracy of fitment - On the Homepage, please enter (complete) your vehicle’s year, make, model, sub-model, and engine size. Type the part's name in the search box. Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.
