For those of you that have done this I hope you can shed some light on this for me. The mechanic at my dealer told me that when installing rotors on the vehicle, there is a mark on the rotor and on the hub that are hard to see, but need to be lined up to keep proper balance, otherwise there may exist a problem of wheel balance if the rotor marks and hub marks are not properly lined up.

I've looked at the rotors and to me they seem easy enough to remove and replace. Can anyone clear this up? Down the road I will need to change the rear rotors and pads. I would like to do it myself.

Thanks in advance
