vibration in steering with drone noise in powertrain on 2000 Volvo V70 XC

Car has 170000. I have had it for 7 years off a lease. Serviced religiously at the dealer.Have all the records Developed a drone like noise and vibration in steering. Dealer had it for 25 days...replaced rotors/3times, rebuilt front and rear ends, replaced tire, replaced pads, replaced coil in distributer, replaced fuel pump..and they didn't even take me to dinner. I called Volvo corp. in North Jersey. Advised me to take it to another dealer. I think it may be the power train. What would that costto repair/replace?? I didn't want to get in to a car payment right now but Ialso need to know the vehicle is safe. I'm on the road for my job.

did you get your car fixed? Have you checked your brake rotors? and if you turn the wheel slightly does the noise stop?
"Power Train" is a general term that encompasses the transmission and drive axles so an estimate is hard to give.
Can you explain when this noise/vibration occurs? What conditions? Vehicle speed, engine speed, what gear your in etc.
