So I just finished replacing my front rotors and break pads on a 2000 Grand Vitara. The passenger side rotor was very stubborn; was rusted on very good. Needless to say, I had to bang on it to get it off. In the process, the toner ring popped loose and is now just sitting loose on the axle. I'm not an advanced mechanic or anything so I'm not sure what I can do to solve this problem. Can I fix this myself or do I need to bring it to a shop?
