Condition
Some customers may comment that the sunroof glass rubs on something in the roof or that the glass rattles when the sunroof glass is partially open.
Cause

Correction
For a gap of 1/4 inch or less at the back of the bow to the roof:
1. Remove the headliner and sunroof module.
2. Plastic off the interior for protection.
3. Pull down on the roof bow slightly and remove any anti-flutter compound.

6. Push the back of the bow up to the roof to within 1/8 inch and squeeze 3M 08116 or equivalent between the roof and the bow in four roof locations.
7. Let it set for 24 hours.
8. It may be necessary to pull down on the center of the roof so that it is flush with the sunroof glass when done because it was pushed up during the repair process.

10. In some cases, it was necessary to elongate the holes for the sunroof glass attaching holes so that it was flush.
