Squeaky steering wheel
#4
My 86 non-airbag wheel started grinding while turning. I took the wheel off and found some old hardened grease. I then cleaned the brass contacts and applied a thin layer of grease onto the contacts and the sound went away. This may help you.

You'll find screws behind the air bag holding it onto the steering wheel. Once that's off, you can unscrew the large nut (24mm or 15/16") and take the steering wheel off. Be careful of the clock spring (that's what connects to the air bag) - you don't want to break that.

I have squeaking that I believe was between the inside surface of the indicators and the tab that cancels the turn signals. I greased it all up and eventually the squeak went away, but it took a while.
