Group:
The rear of the sunroof on my '98 S90 sags a bit and it has been sagging more and more in the past year. Causes wind noise anywhere above 30 mph.
The front is OK.
The FAQ says how to adjust the glass in the frame by loosening the four screws with 8 mm / 5/16 heads and lifting the glass.
I have done that and I am at the top of the adjustment with none left and a noticable sag.
No other info on the S/V90 roof.
There is a space between the gasket at the rear and the roof.
The rear just does not lift high enough.
I filled it with some screen piping about 3/16 diameter and it cured the noise.
But now I cannot use the sunroof.

The little rollers that follow the track do not appear to be worn too badly.
It is the RR corner that is the worst but that side roller is not worn more than the L side. All in all I think there is something wrong with the rear of the frame in the car.

The question is can I remove the glass by removing the four small screws holding the tabs and lift out the glass?
Will that allow me to see how the interior frame can be lifted, perhaps with a shim.
Can that interior frame be lifted?
If the frame cannot be lifted, can I grind the tabs on the glass frame to elongate them enough to gain more adjustment range>

A local sunroof shop says he would have to look at it.
I suspect he does not know much about it and it will be expensive.

Thanks in advance!
