3.0 1977 Steering wheel rattle

Hello
Havnt posted in a while, but wouldnt know who to ask but this fine group..:

I am driving on a lot of cobble stone recently, with my 77 3.0 turbo. There is a loud rattle in the steering wheel on cobble stone, if I hold the back cover of the steering very firmly, it dims.

I have dismantled, cuhsioned the springs (for the horn), really tried to figure this one out but cant.

Anyone?

Image from recent 3K KM trip Berlin to Lisbon attached, for eye candy
She drove beautifully, 3K KM in 3 days, with half a liter of oil consumed...

When you hold onto the steering wheel and lift up and down does it seem a little loose? If so it could be your steering shaft going bad. There are aftermarket replacement bushings available that are somewhat easier to install than a factory bushing replacement.

I solved my rattle today. Problem was I had rattle / 'thumps' sometimes at high speeds, always at low speeds on cobble stone or similar. However the bearings felt firm.

Turns out the universal joint on the intermediate steering shaft was loose and had play. Not suren if the few turns to tighten the bolt saved me from loosing steering and hurting myself at some point but def fixed my problem.

Where do you access the intermediate steering shaft?

this first. its easier and cheaper.
you just press the new bushing in and it pushes the old one out.

Canít remember the setup. Doesnít the old bushing then press against the upper bearing at the dash?

What Rahl is talking about is the Mitch Leland nylon replacement support bushing, which our host sells for $29. I have one, never opened, that I never used and waited too long to return. I'll sell for $25, including shipping, if anyone needs it.

Here's the part (bottom of page):

And here's a thread explaining what it does:

I did the 928 bushing on my car. you just knock it in and it pushes the old one out and you are done.
I see the mitch bushing gets great reviews.

This was one of the first things I did to my car after purchase. Actually on the test drive the steering wheel felt loose, the shifter rattled and had to hunt for the gears a little. This all helped with the negotiation and final price.
I was surprised how easy this fix was, a little easier than the shifter bushings and the shift rod and shift collar bushings. All was tight after these easy mods.

I did check the steering wheel off move to check the bushings and moved the steering column for play - no play. Almost impossible for the rattle to come from there, as it is clearly metallic, on cobblestone it feels like a loose screw or mounting. Steering has zero play, either.
