basically exactly wat the title says. When i accelerate while turning, i hear a rattling noise. Did some research and it might be cv joints. does anyone have any input on this or anyone have had this issue? if its the cv joint, are there front cv joints on the z cus why else would the noise only happen when accel when turning?

 

You don't have "Constant Velocity" joints, that term is used for front-drive cars where power is applied to a wheel that also must turn left and right.
You do have upper and lower ball joints on each side as well as multiple bushings. I would think about it like this, 3 possibilities -
Something is either improperly loose, worn past it's useful life or needs lubrication. The easy answer is most brake and exhaust shops will due a free safety inspection, someone with some training and a lift can look at it and mb find your problem. Gl!

 

What year is the Z?
could be blown out bushings

 

this is exactly the sound it makes: watch at 0:20
but the thing is 350z only have a rear axle since its rwd right?

 

Good ole Scotty!

 

For what it's worth we understand you have an annoying noise when turning and accelerating. In Scotty's video at 0.24" seconds he states clearly that he's looking at a FWD vehicle and replacing a 1/2 shaft (which Z's do not have).
Have you taken it for a free inspection as suggested earlier? Gl!
