Hi, welcome to Just Answer. I'm acuramstr. front or rear?
You will need to remove the hub assy to press the bearing to replace the studs. Here's the procedure . After you remove the hub you will need a press to push the hub from the bearing, most auto parts stores can do this for you . note: this is the correct way to do this. you may hear that you can do it by grinding the studs and notching the back plate but this is a safety issue and i will not recommend that you do this .
