Hey guys,

I bought the 74 260z in November from a guy who had it on jackstands for 5 years. I rebuilt suspension and swapped to 71 SUs. Took it for a drive today and went to McDonalds about 2 miles. Once leaving, I noticed 2 noises I didn't notice before.

1) From the transmission tunnel a sort of constant wooooossshhhhhh noise. Could this be due to transmission fluid? Haven't really checked it out yet, might be a good idea to check it.

2) From the rear, maybe differential, a constant low whine I'd say describes it. Also, haven't check any fluids in that.

Other than the fluid possibility, are there any other things to check out? Can hear a know, might be u joints, when accelerating kinda hard.

Anything will help a ton!

-I also have this problem, Does it go away when you engage the clutch? If so then it's probably the throwout bearing. I would also check the tranny oil because if it's low it could be contributing to the wear. Change it to redline MTR and it'll shift alot better.

-Mine has a low whine, but it always has since I can remember. I think it's common in these cars. Check the oil, if it's old change it.

Wow, thanks! I will check all that out. I can't remember if it did it while clutch depressed or not. But I'll let ya know.
