Ping sound in left rear suspension ?!
 

I have a fairly new 35d (1500 miles on clock) ..noticed that sometimes when I drive over small humps / gutters etc that I can hear left suspension make a bit of a metallic 'ping' sounds - is that normal? car seems to drive fine and nothing seems out of place when I've inspected etc ...

is it just a running-in thing? thoughts? :dunno:
