A horrible experience when it occurred. I thought a front wheel was coming off. I was on the Washington DC beltway going about 60 mph when is happened. Fortunately it was early on a Sunday morning and not much traffic. Also, fortunately, I was in the right lane and was able to get onto the shoulder. I got out expecting to see a wheel about to come off but nothing. I drove very slowly to the next exit and got off an reexamined the front. Finding nothing, I slowly drove home.

very scary. happens when hitting decent sized bumps while going 45+ absolutely horrifying on freeway and you need to completely stop in order for the shaking to stop.
