I get a bad vibration at 60mph... I can notice it at other speeds but at 60 it is the worst. I had the tires balanced thinking that was the problem but it did not fix it. Wondering if it is a wheel bearing or ujoints? What is the best way to tell? This is on a 2010 Screw with 181K

 

I've had to have wheels balanced twice before. Road force balance machines are much more accurate.

 

Turns out the tires were bad. I knew they were worn but they still had decent tread. The tread was separating . Had new set put on and it drives great again. I am surprised that the tire store I took them to have them balanced did not tell me I needed to replace them.
