T-case rattles at 60 MPH...suggestions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

It's a mutt (body from C20, frame and running gear from K20) 350 with 4 speed manual and I believe the 205 t-case. Shifts in and out of 4hi and 4low well.

When I approach 60 MPH the t-case shift lever starts to vibrate and make noise. Gets louder as I increase speed. Sounds like the linkage is rattling more than anything else. Suggestions?

I can certainly live with this because the truck isn't my daily driver. Wondering if I've got a slight kink in a shaft causing a little wobble. Or bad bearing in the case?
