i have an 86 300zx and i need some help on a noise that im hearing from the rear-end. i'v pretty much narrowed it down to 2 things, but could be wrong. either wheel barrings or axels. its kind of a clunking noise and i only hear it when the car is cruising or slowing down, but if i use the breaks hard enough it doesnt make the noise. i also dont notice it while im accelerating unless im shifting. also i notice it when im going around right curves... any help would be greatly appreciated,i know if anyone can help me out its nissan-tech
