Rattle Noise Ram 1500 6"

[uncler]

Hey guys, need a better mind...I lifted my 2010 Ram 1500 4x4 June 2014, 6" Rough Country, and it's run great so far. 38,000 miles and I don't beat it up I take care of it...stock tires For now, but for the last week theres been an annoying rattle noise under my front end any time I go over bumps. My passenger CV joint/shaft is leaking a very small amount of grease and I think its the CV thats making the rattle...anyone experience/ know what it could be. If it is CV joints, will replacing it kill the rattle ? Or will I need to go further. Any advice helps
