ᐅ Why does my Billy bookshelf squeak when I open it?

I have an Ikea Billy bookshelf that has started squeaking when I open the doors. Overall, it is stable and properly assembled, but every time I open the doors, there is an annoying noise coming from the hinge area. I am mainly interested in understanding why this squeaking occurs. Are there mechanical causes, such as material friction, assembly errors, or lack of lubrication? Most importantly: How can I fix this permanently and easily without having to disassemble the bookshelf? The exact noise comes from between the door and the bookshelf frame; the hinges are simple pivot hinges, not a soft-close type. I would really appreciate any tips on what might be causing this and how to solve the problem.

The squeaking usually comes from dry hinges. Simply apply some commonly available lubricant—such as WD-40 or sewing machine oil—to the joints, move the door back and forth several times, and the noise should stop. Another possible cause can be slight shifting of the hinges. If necessary, tighten the screws.

The issue with squeaky Billy bookshelf doors can be easily explained from a technical perspective. The hinges used in Ikea Billy units are simple metal pivot hinges encased in a plastic housing. This combination of metal and plastic can cause friction noises if not properly lubricated. Additionally, the screws attaching the hinges tend to loosen slightly over time, leading to minor movement and resulting in squeaking.

I recommend the following steps:
1. Check that the screws on both the door and hinges are tightly fastened. If necessary, tighten them with a Phillips screwdriver, but avoid overtightening to prevent damaging the wood.
2. Then apply a thin layer of lubricant—such as silicone spray, light machine oil, or lithium grease—directly to the moving parts of the hinges. Do NOT use graphite powder, as it attracts dirt.
3. Slowly open and close the door several times to allow the lubricant to spread evenly.
4. If the unit is very old and the hinges are heavily worn, replacing the hinges might be worthwhile, although this is seldom necessary.

By combining tightening and lubrication, the squeaking should reliably and permanently stop.

Exactly! Those little things sometimes have their own party when you ignore them 😉. A bit of lubricant works wonders – I usually use silicone spray because it isn’t sticky and stays clean.

Sometimes repeatedly opening and closing after applying lubricant helps it get into all the crevices. If there’s still noise afterward, it could be due to loose screws, so it’s not just about maintenance.

Good luck with your silent shelf! 🙂

I would also point out that tightening is not always the best first step. Over-tightening can damage the threaded inserts in the wood, especially if the shelf is older or has been moved frequently.

In addition, it’s worth considering whether all the hinges on Billy really have the same design: there are versions with metal and plastic parts, and their noise behavior differs. The silicone spray you mentioned is definitely better than WD-40, as the latter may temporarily eliminate squeaking but tends to act as a thinner over time and can remove any lubricants from the material.

A more sustainable solution might be a specialized grease that stays in place longer.

What I would also be interested to know: how often are the doors used? Frequent use can increase material fatigue, which should also be monitored.
