The other day I wanted to install my dog grid (the one with the dampers), which I had acquired from an MT member in my 850 station wagon. Both plastic covers in the sky above the rear seats were quickly removed, also the two screws – one of them relatively heavy. But when I turned the second screw in it happened: the welding nut loosened and the screw is stuck in the thread (the welding nut spins with it). I know through my service documents that Volvo has not really pointed at some welding nuts (especially the railing nuts), but it’s off. Today I have bent away the sky at the relevant place from my battle-850 and saw that I don’t get between the sheet doubling (column about 1cm). What now?
