1993 Plymouth Grand Voyager

I am thinking about buying this Mini-Van, but I noticed a noise and vibration when turning to the right and accelerating. The grunching sound and vibration come from the left when turning to the right. The noise and vibration are not noticeable when accelerating while driving down the road. There are not any clicking noises while turning so I don't think the problem is in the cv joints.

I was thinking the problem may be in the front wheel bearing. Or perhaps you could tell me if a transmission could cause this noise.(I hope not).

Thanks for any advice.
