So I am hearing a rattling sound coming from the driver side rear of my buddies car. I checked all the nuts and bolts to be tighten, no issues. I've shaken the wheel back and forth. Nothing rattles... Only when your driving... Is the bearing?? If so where do I get the replacement bearing... I know it needs to be pressed in

 

the bearing dosent need to be pressed in.. it is sold as a whole.. u just un bolt the nut.. and pull it off. and slide the new one on.. it could be the heat sheild.. or rocks in there.. plenty of things..

 

I think the sound is coming from the driverside rear brake pad. It looks to me it's missing the pad spring.... This could be a cause and will be replaced 2mro.
