scraping, marbles rattling sound
 

Hey there. Yesterday while driving all of a sudden i got a scraping sound and also sounded like marbles rattling in the front end, I checked everything i could in the front but could not find anything obvious. It only does it when moving Thanks

I'm currently dealing with a ball joint issue myself on a 2000 GMC Jimmy and from what I've been reading you should really check your upper ball joints and make sure they're doing ok. This might be WebMD-itis but if it's your ball joints then yours are in worse shape than mine and that is a bad place to be.
