The problem could be a bad wheel bearing, ball joint, tie-rod end, CV joint or loose strut. The first thing I would suspect is a CV joint on the front axles. All of these things are easy for a tech to identify once it is on a lift. In the meantime, jack up one side and get a look at the rubber boots covering the joints. Use a mirror on a handle. If they are ripped, then water got in there and the grease came out. A bad CV joint would bind up on a turn but be OK going straight. The cynic in me suggests the previous owner knew the CV joints were bad and didn't want to shell out the $4K the dealer wanted to repair. I hope I am wrong.
