Front End Vibe - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an annoying vibe in the front end of my 87 1/2 ton 4wd. The balljoints and wheel bearings are tight, same with the tie rod ends. Basically, anywhere around 65, the truck starts to vibe slightly, sometimes worse then others. Not too bad but enough.

I had a worse situation and swapped rims/tires. Got alot better but I still have a slight vibe. What else in the front end could cause it? Can old leaf spring/sway bar bushings cause the vibe? My steering stabilizer is shot but I don't see that causing this.

Any ideas? It may be the tires but I'm trying to eliminate other things first.
