For two weeks I have been the proud owner of a 92 V8 4.2. Completely original condition and technically impeccable. That's how he's supposed to stay.

It all works perfectly except for a little something. When driving, I have a squeak from the steering wheel (this only occasionally) or. a noise of scrap as if paper were rubbing on something. I've taken off the steering column panel before. I'm afraid I haven't discovered anything. I thought the airbag cable (if that's what it is) was the troublemaker, but I was wrong about that. Do you have an idea?
Thank you very much for the help!
