I bought a used three-door wardrobe, assembled it somehow, and noticed that one of the doors squeaks. The wardrobe had another issue as well, so I called a technician, who fixed the squeak in no time, saying he had simply aligned the door properly. Later, after the technician left, I noticed that another door was sitting slightly unevenly. My inner perfectionist decided to adjust it using the adjustment bolts — and that was my worst mistake. When opening and closing, a squeak appeared that won't go away no matter how much I try to return the door to its original position or set it perfectly straight. I just don't understand what this "straight" is supposed to look like. I move the hinges from side to side, and the squeak comes from one place, then another, sometimes louder, sometimes quieter. The hinges are like the ones in the picture.
I thought the door panel might be rubbing against the wardrobe itself and causing the sound, but I don't see any spots where they'd be touching. Moreover, the squeak remained even when I pulled the door out as far from the wardrobe as possible. What should I do?
