    Yesterday I got in the 40 and took off down the road. Bad vibrations out of nowhere. The RPM really doesn't matter and the sound is definitely coming from the rear. I think maybe u joint but I was also thinking pinion bearing. It happens in second, under power and third when I am lugging around 20mph. Not bad in 4th or first tho. Any ideas?
