ᐅ My KALLAX unit creaks even more than before after tightening the screws?

Hello everyone,

I have an issue with my KALLAX shelving unit from IKEA: After reassembling it (I completely took it apart and rebuilt it to make it more stable), it now creaks much louder in several spots than before. It makes really unpleasant noises as soon as it is moved even slightly or when light pressure is applied. Before the reassembly, it wasn’t completely silent either, but it was noticeably better.

I followed the instructions carefully and checked everything several times; the screws are tightened properly. Still, the creaking has gotten worse. Has anyone experienced something similar or have tips on how to identify and fix the problem? Maybe the material or certain components play a role?

I would really appreciate a collection of ideas, possible causes, or proven solutions, as I would like the shelving unit to be quiet and sturdy. Thanks in advance!

That sounds really frustrating, especially if you followed all the instructions! With KALLAX in particular, it’s annoying when creaking occurs because the parts are supposed to be quite sturdy.

What has helped me in similar situations: Sometimes it’s not just about the screws themselves, but the wood fiberboard panels that can slightly deform under tension when the screws are tightened. Make sure not to overtighten the screws, as this can unevenly compress the panels and often causes these noises.

Have you tried loosening certain spots and then lubricating them, for example with a special furniture wax or some Teflon oil? This can sometimes reduce the friction.

Double-check all screws to ensure they are properly seated. Sometimes a slight adjustment helps.

Avoid overtightening the screws. Use washers if necessary, provided the construction allows it.

I agree! With KALLAX, it’s often noticeable that the particle boards and the pressed wood strips can really cause creaking. 🙂

Maybe try using a bit of silicone spray or furniture wax (make sure it’s not sticky!) to make the movements smoother when tightening and loosening the screws.

Sometimes a very gentle change in the order of screwing helps too, for example, tightening screws on opposite sides first, then adding the rest.

Another option: Check if the shelf support strips are properly positioned and not under tension. Often, they exert more pressure on the side panels than expected.

Is the shelf placed on a completely level floor? Unevenness can increase the pressure.

For a systematic problem analysis, I recommend the following:

1. Check the fit accuracy of all connection holes and screws.
2. Ensure that the chipboard or wood fiberboards are not damaged by over-tightening.
3. If available, use suitable washers to distribute point pressure.
4. Verify the levelness of the installation site with a spirit level.

Squeaking noises are caused by friction between components, often due to excessive point pressure. If necessary, slightly loosen the screws and then tighten them evenly.
