Hi everyone,
I started the thread back in 2015 and since then I replaced the front prop shaft with a Tom Woods but still had the vibration.
I ultimately installed a set of BFG All Terrains so even though the vibration may still be there the new tires don't make it seem as noticeable....
I've put on about 45,000 miles since then and nothing has fallen off...
I have come to lower my expectations of what I can "fix" on the truck, that came with watching the ratio of $:sanity tip away from my favor on both accounts.
On the plus side, I did get a cool Tom Woods sticker that says "My shafts a Woody"...
Good luck on your crusades!

 

Any updates on this? I'm having same exact issues.

I do want to note that one of the changes before I had this problem was a cheap hub I bought off Amazon to replace right front hub. Anyone have issues with aftermarket hubs?
