Could any one share some light on why my car makes a grinding noise from the rear when u turn around corners?
I've only recently upgraded the handling to my 318i. It now runs bilstain challenge spec shocks n springs, eibach anti roll bars, fully poly bushed, disk beam with a 3.91 LSD medium case.
Could the noise be coming from the diff?
Any advice would be great thanks.

My money is on disc backing plates rubbing disc very slightly

I've checked that, good clearance there, if that was the case it would be grinding when driving in a straight line as well. Thanks tho.

Not totally true, i've had several cars that the back plate was so close that corning, will cause any tiny freeplay in the bearing to be exagerated at the disc surface causing this noise. Not necessarily rubbing at the disc edge either

I'l investigate again. But I don't think that is it. It ain't that type of grinding noise. Would LSD plates make a noise if worn?
