100k DC with vibration

I have an 06 SR5 doublecab that has a vibration at 62-67 mph. I've had the wheels/tires balanced more than once to ensure that they are balanced, and that the rims are straight. One other thing, I've replaced one of the front half shaft axles with an aftermarket. Could it be possible that this axle isn't balanced? Could it be something else such as the rear driveshaft center bearing? Any help/suggestions are very much appreciated.

Thanks
RJ

 

Can you feel the vibration in the steering wheel? If so you might want to rotate the tires and see if it goes away.

 

Yes, I can feel it in the steering wheel. I'll rotate them and see. Thanks for the reply.

 

Did that work? I think I have the same vibration.

 

Its might be the U-joints in your drive shaft...thats what was causing my vibs


The trucks in the shop as we speak getting its driveshaft re-built
