Update one my truck...
Dealer did the standard rotate and balance of my tires and I have put on 100 miles or so since. Now my steering wheel vibe is about 98% gone and I can easily live with how it feels. Greatly improved! I do still have a vibe through the truck that really only starts over 75 MPH and can really only be felt in the seat of the pants. I can see my passenger seat just vibrating away at 80. What is weird though is on some pavement it vibrates pretty good and other pavement it is smooth enough that I would never have a second thought about something possibly being wrong.
Just thinking outloud here....my mind started wandering and wonder if my problem is just a combination of suspect tires and the factory shocks being crap IMO. It almost feels like what some other manufacturers have had problems with, bed bounce. I am just about to ready to throw my Bilstein 5100's on the truck with some tires and roll the dice. I should probably talk to the service manager first about that thought in case they want to try and blame aftermarket parts on my issues.
