I’m trying to remove a damp carpet and this gear knob needs to be removed first. At first I tried to turn anti clockwise but it was just way too strong. I then used a spanner just underneath the knon(you can see the nut looking thing). This was really strong but it did work a bit and seemed to move the gear knob up. I know it’s working via a little space seems to be created under the knob and the gear locations diagram is now at an angle.
However the knob is no longer turning and the spanner doesn’t seem to be hooking tightly it just turns without turning the knob. It feels as though thevspanner scrapped metal if he surface of the nut and you can see in the picture the metal under the gear knob is detetiorating.
Anyway how can I get it off and it seems I’ve f d it up? Why did the spanner carve the metal off?
Anyway what can I do to salvage the situation? I need to move this ASAP as damp situation is getting worse. Please help!
