Please let me know what you find out and i'll do the same if I can figure something out.....I was thinking of checking my u-joints next

 

are you on stock height? If so the factory camber toe/angle is set a little negative, because mine use to do the same right around 60+mph and one day I was feeling around the inside of the tire, if you rub it back n forward enough you can feel the inside of the tire being a tad bit wavy

 

Yes, I'm running stock height on 18's. My Camber is -1.1, left and -1.3, right. I've been told that the camber isn't adjustable which is disappointing but is there anything else that can be done to correct this problem or do I need to learn to deal with it? I really don't want to destroy my new tires if that is what is happening. I've seen some people talking about camber kits, what are these? Just for lowered vehicles? Any help would be appreciated

 

Always keep in mind that tires are usually the only rotational item that change with temperature as the rubber changes and PSI changes the diameter. So if the vibration changes at the exact same speed as the tires go from cold, warm, hot. You have your answer.

Now rotors can change from cold to hot but this usually requires actual mild braking to identify.

 

Mine did it on stock height, I went ahead and bought new tires and did a alignment right after
