Is there a cure for noisy t-case shifter?

I am off the SWB board, but figured the folks here would probably be more familiar with the problem, since I think it is pretty common, but the search came up with nothing.
My tow rig is a 1980 Suburban with a 350/th350/205 setup and the t-case shifter has an annoying rattle at highway speeds. Everything works correctly (indicator light, shift detents, etc.) it just has this rattle. Is there bushings on the shift rail that can be replaced or some other fix?
Thanks for any help.

Resurrection Joe, a guy on here, just replaced his shifting linkage and bushings on his 205. He should be on this evening. My 205 is sitting behind my house waiting for my project to get to that stage so I haven't had a chance to experience this yet.

<font face="Times New Roman">
<font color=green>Yeah, I had that problem, discussed it in a post about 3 years ago...[img]images/icons/shocked.gif[/img]. Here's what I posted then...

If you take apart the linkage under the truck you'll see that the original bushings are probably really worn out. Go to the hardware store and get some bronze thrust washers to replace them, this will help reduce all of the slop at the shifter. Also buy some quarter inch thick rubber from the hardware store also and cut it to the size of the baseplate for the shift boot. Then cut a slit in it to pass the shifter through. This increases the side-to-side tension on the shift lever to further stabilize it. If you cut up some felt auto carpet insulation and put some of that in there to will help to deaden the noise that comes through from the transfer case. I did all of this a couple of weeks ago and it made a huge difference. I can actually hold a civilized conversation with a passenger when I'm moving faster than 65 mph, where before the noise at that speed was intolerable.

Basically just a matter of replacing the bushings with new ones. I used these bronze stepped bushings I found at the hardware store and it worked great.

Thanks, that is kind of what I was thinking about.
