Clattering Noise LHS - Exhaust?

[bg1]

Hi,

Have suddenly developed an occasional clattering noise from LHS underneath. Have looked underneath and think a mounting bar has snapped off rear box?

Do we think it's this and if so how difficult a fix?

I had a very similar sound a few weeks ago that I thought was either the exhaust carrier or a heat shield.

Turned out the spring had snapped about an inch up. Garage removed the broken bit, no noise since. New springs on order.
