Hyundai Repair: fluid leak as well as wheel vibration, vibration 2001, wheel vibration

Question
2001 Sonata.  Fluid leaking front passenger.  Alot after long drives. Suspect it's oil but there is also a vibration feel and noise from that wheel.  Rotated tires and noise stayed.  Are they related or two problems?

Answer
Chances are they're separate issues.  The only thing I can think of that would cause both issues would be an internal transmission problem causing both the leak and the noise, but the fluid should be under the center or left side of the vehicle if that were the case.  

If you know the noise is coming from the right front wheel, you should suspect brake pad wear or perhaps a bad hub bearing.  For the fluid leak, you'll need to climb under and have a look.  The oil filter is in that area, so you might check there first.
