Hissing/sizzling or trickle sound when making right-hand turns

Hi, when making right turns either on roundabouts or general right hand turns, I hear either a trickling sound or a hissing/sizzling sound coming from the left hand side of the car around about where the front passenger door hinge would be..



I popped the bonnet one time when I came off a roundabout having heard the hissing/sizzling sound but nothing seemed to jump out at me and the sound only happens during the turn.



Can someone help me diagnose the issue please.. Wouldn't be sure where to start..



Thanks
