Steering wheel knocking, where to find gelzer 1318dl

[Bmwe5320023.0]

Has anyone repaired steering wheel knocking when you turn left/right by replacing the shims in the steering rack?

I found this video, it's it russian, but maybe some AI can translate it these days 🤣

In any case, I haven't come across thus repair on any other bmw channels or forums

And I can't seem to find this part anywhere, gelzet 1318dl

So apparently these plastic shims wear out and cause loseness, which makes the steering knock/clunk.

This video shows what he does, seems like a pretty simply job. Any thoughts/experiences??
