You will need several tools to replace the bearing besides a socket set of metric and standard sizes to remove the wheel and brake caliper.\015\012A 36mm socket (may be rented at some auto parts stores)\015\012An Impact Wrench for the 36mm socket (air or electric should work)\015\012A torque wrench (IMPORTANT!)- the 3 rear bearing bolts (12mm?) need to be torqued properly or else they will fail and cause the wheel to separate, i believe they need to be at 75 ft/lbs. Please check.\015\012Do not attempt to do this yourself unless you have the proper tools and know how to use them.  I recommend getting at least the Haynes manual that the stores have or buying the Dealers Service Manual (expensive but thorough and usually available on ebay!)
