Well upon learning the schedule of my 8 month old (in a different vehicle) required a prompt departure and return time I decided to tempt fate and make the 2 hr highway rnd trip without replacing them. Definitely getting some feeling from the back end upon our return. My wife who was driving behind me said my back right tire was slightly wobbling, which I could feel above a certain speed (can't say what, speedo doesn't work). This leads me to believe that the wheel bearing is going too. Wee! Just got the truck back from 10 months in the shop, glad to see there's plenty left for me to tend to....

Back to the U joint, I'm going to try my hand at it now, I'll probably tackle that, and then the wheel bearings if that is what it ends up being, I suppose the tire could be mounted off or imbalanced but I doubt it, I don't think its been off since I got the truck and it was fine before.
