I've got a 72 240Z that was recently rebuilt front to back. It runs great but noticed on a drive yesterday that when turning at speed (e.g., >30MPH) with some side load on the car going around a curve I can hear a distinct scrapping sound in the back. It's fairly high pitch, and sounds somewhat "Tinny". No tires are rubbing on anything, and wheels are tight on the hubs. Any views on what this might be? Something with the bearings? Brakes dragging a bit in the drums with a turning load on them? Something with the axels?
Thanks!!
