Title: Horn Update
Post by: su8pack1 on August 19, 2021, 23:04:10
I received my rubber grommets from MB, and a NOS horn contact ring. Put it all back together as I took it apart and still have a slight problem. Much better, but not perfect as it sticks on sometimes and I have to pull back on the top of the chrome ring to stop it. I have searched the internet, this site and manuals and cannot ring a decent picture or diagram of an exploded view of the steering wheel assembly. I have the Big Blue Book and that's not much help. I didn't find anything broken, just the dry rotted grommets which isolate the chrome horn ring from the wheel. Anybody have experience with this?

When you say "rubber grommets" are you talking about these?

Yep, I put 3 new ones in that the back of the horn ring sits in. In the picture they're a the 12, 3 & 9 o'clock position. The old ones shown.

I put in these new grommets (or bumpers, buffers) and it was not enough to stop rattle. I added pieces of rubber sheet with self adhesive - then the rattle was gone.

Do you have a picture of the material and location - I still have this problem and would like to address... Thank you

I think it was just piece of sound dumpening bitumen mat with self adhesive, about 2mm thick. I punched ca 6-7mm round pieces.

I feel I need to work on this .. my horn only sounds when I put pressure on certain areas of the horn ring.. but dangerous if I hit it in emergencies and nothing happens… could this be the problem?

The round brass ring above has contact points in like the points in the distributer. Try cleaning them with fine emery paper.

13mm socket, Philips screw driver, flat screw driver.
Carefully pull off the center pad,
Remove the 5 bolts and washers.
Pull off the wheel and remove the 2 wires,
Lay the wheel down on a towel,
Remove the 3 Philips screws and lift off. It can only go back together one way so no problem putting back together.
Replace the 3 rubber grommets while you're in there. I ordered from an MB dealer on line and it took a 2 weeks to get as they had to get them from Germany.
Clean the contacts in the brass ring as necessary.
I took it apart 3 times before I got it right, but everything now works fine.
