The noise could be coming from the boot on the steering shaft were it goes threw the firewall, sometimes goes away if you can lube the area between the shaft and the boot. also sometimes it could be the clock spring. The noise could be coming from the front suspension (strutt tops). The only way to tell is to have dealer tech thats good with noises to ride with you so you can pinpoint the noise. Or you could try it yourself by getting a mechanics stethescope and listen for it.
