Steering wheel squeaks ...

Hello, everybody.

My steering wheel drives me crazy, here's the thing:

First a "chhhhhrrr* while steering, I then smoothed the grinding contacts for the horn with 2000er sandpaper and a round Teflonspray, after that was quiet.

Then:
To the middle position a *ieeku* while shunting and steering. I then sprayed the co-driver on the steering wheel for the turn signal and the mechanism in the steering button with silicone grease spray. Take a few kilometers to rest, then the sound is back.

The steering pole switch itself sits firmly in the panel, which itself does not squealish, the same applies to the plug connections. Even the panel itself sits firmly on the steering column and does not squeak.


Someone give me a tip on how to get the sound?



P.S.: The thing reminds me: Click!
