I have a 2010 Silverado 4x4. My truck has decent vibration at any speed. I've replaced just about everything. Struts, shocks, upper control arm w/ ball joints, lower ball joints, inner and outer tie rod ends, sway bar links, hub bearings, all new brakes, all new ujoints. MY tires are in good condition and fairly new, keep them aligned and road force balanced. But after all this by truck still vibrates badly while driving (not idling), bad enough to the point of actually being able to see the empty passenger seat vibrating. It is incredibly aggravting :evil: Any ideas on whats going on would be greatly appreciated! TIA

drive shaft or u-joints is my guess. Well I re read so forget u-joints. Are the u-joints phased right ? Does it vibrate under certain conditions ? Under load, decelerating, certain speeds, all speeds ? Can you tell at all if it's front or back of truck ? Take a passenger with you or a driver and move around in the cab to see if you can isolate a location.

Have your tires balanced without road force. If they don't know how to operate the machine correctly they can get it off. I'm not really sold on the road force anyway.

Notice weights knocked off of the drive shaft, hit damaged etc.
Tires out of round? Do you have a dial indicator to check?

If there is vibration at even low speeds, it would not be suspension or wheels/tires. Check things that rotate at a speed even at a low ground speed. Drive shaft or transmission.

So after chasing this vibration issue forever I finally found the problem. My transfer case went out, I replaced it, and now my truck rides smooth as glass
