own a 2003 nissan 350z coupe. when i get to about... 15 maybe 20 mph But when Decresing in speed.. With the car Not in gear. Car in nutral or clutch pushed in(same thing) it makes this... Tickking noise, which slows down when reaching slower and slower speeds. So its obviously drivedrain. its not the brakes or tires i checked those out. Also pushing brake does no difference. Only difference in when you put it back into gear and let go of clutch then it stops...
So.... some Bearing with the driveshaft and rear end? or driveshaft and tranny? something like that i have no idea.. but when its in gear it doesn't do it. push it clutch it does it.

Any ideas or similar problems that occur to these cars often?

 

Could be the "axle click" noise that some get. I think there was a TSB on it, has to do with the lube getting old or something.

Had same problem. Went away after changing pads.

 

thanks i think i got my answer on that Axle ticking thread you sent me. Seems like an easy fix! my Pads are pretty well all around. Rotors are clean not bent or worn in more than certain areas. my Calipers seem to be a Bit more loose then im used to.. But no matter how hard i tighten it stays that loose. so must be right.

thanks again
