You can replacement the mounts at either the yard (may be worn also) or go to the dealership and order two new mounts and screws. The mounts come out relatively easily. Use blue locktight on the threads of the new screws and don't overtighten. You should also grease the tracks using either teflon spray or lithium grease to make sure the sunroof operates easier and reduce the stress put on the crank assembly. I have also found that you should crank the sunroof slowly to ensure the roof doesn't come off the track.
