Quoted from NovaCade:Just take the glass out, then loosen the nut at the top and bottom that hold the rails on, they only need to be hand tight, then back the two black screws out on the other side of the rail and that will almost for sure solve your glass issue. Worked like a charm on my last two pros. One being Godzilla
This seems to be the culprit.
Someone at the Stern's factory is cranking the screws down too tight on the glass guides. Factor in the crazy humidity we have been having lately (which expands wood) and we have the ultimate death grip vice.
Quoted from Pinash:Wow that’s it? I may try this tonight. I wonder if shimming them off the cab (maybe some washers) is a better long term fix.
Just loosening the screws on glass guides is all you need to do.
