Strange vibration in steering wheel when turning

[JeTexas]

I've got a 99 996 Cab C2 6-speed with 125,000 miles. Over the past month or so, I've developed a vibration in the steering wheel when I'm turning. It's quite a judder and will even make noise if I'm turning into a driveway or anything uphill or on uneven pavement. It originally was only when I turned left, but now it's starting to vibrate when I turn in either direction.

It feels like there's some bushing in the steering column that's gone missing and it's letting the move up/down and in/out a little bit. However, I'm not sure if there's anything like that in the column. I don't know if I should start opening open the steering column and dash to look in there or if this is indicative of something gone awry in the suspension. Perhaps I should be looking at the bushings on the control arms or replacing my shock absorbers. I don't know. I'm kind of lost when it comes to suspension.

The ride quality seems to be normal aside from this new steering wheel vibration.

Anyone have any ideas? What should I check first?

I have the same problem with my '06 c4. I read somewhere it has

something to do with ackerman in the steering geometry. I know about

as much about ackerman as I do the infield fly rule. I'm going to the dealer

for an oil change soon and if they have any answers, I'll post their answer.

It turned out to be something not so bad. The airbag / horn pad had vibrated loose enough that it was making noise. I cinched it back down and no more weird clattering noise from the steering wheel when I turn. I guess I didn't get it on tight enough when I took the steering wheel apart last summer to fix the non-stop horn honking.
