Well I just like to say if you don't have a machine shop,don't try,they have to be press fit,and then you'll need to change the abs sensor,and that could run you if you don't go somewhere cheap to get it fixed,call around for the part first get it then bring it to the mechanic to do .part should only be 60.00 and install about 85.00 if they don't need to do both f/r..i have 2 places if you reply I'll get you the name if you haven't done already..
