I have a 1998 nissan pathfinder with 140,000 miles on it. It has a whole new exhaust and front struts. Recently I've been hearing a weird noise coming from the front passenger side I will try to explain as best as possible. When I start driving and give it some gas I get this noise that sounds like something underneath is loose and vibrating almost like a rattaling sound when I get up to about 40 or 50 miles an hour it comes out of it. I checked underneath it and all visible parts are sound. The front right tire is cupping though I noticed this cause I just had them replaced and the it does drive straight down the road. Any suggestions would be helpful..
could be a bent pulley vibrating a belt maybe
