u-joints would be speed related not rpm. if it happens in every gear at 5000 the problem is somewhere between the clutch and fan.

I would look into the fan clutch.

I put a fan clutch assy on my car from a different car once and it vibrated at high RPM. I put my old one back on and it was happy again.

Might be something else as well.
