I had the driver's side regulator
changed. The teeth on the upper end were
gone and there was a crack in the body.
A larger washer was placed with the
bolt that holds it in place at center.

Moral of story: Don't raise your window
to the max. Just top it off enough
so that you have no wind noise.
This will deter flexing of the door's
sheetmetal 'skin'
and prevent regulator damage.
