I sure hope it isn't the wheel bearing. What's happening is that my tires are shaking right at 70mph, and I am getting a squealing noise coming from the rear passenger side of the van when I brake (almost at a complete stop). I looked up U-joints for a 2007 Ford E350 and apparently they do have them, but when I called my mechanic he said that he's not sure if it's a clip, 2 piece or 3 piece and he's going to have to look at it on Monday or Tuesday. I was also told I may have a caliper on the right side that was possibly sticking so I'm not sure if this can cause the problem or not. yeah, It sucks especially when I just got a really good week.
