Advice please

Hi,

My 2015 Scout has just developed a rather annoying and worrying knock/clunk sound. It is normally noticed when approaching bends and slowing down, or when accelerating out of a slow bend, ie a roundabout, and sometimes when turning slowly onto my drive.

This morning the knock/clunk was heard on engine startup, when the car shakes slightly. This has ruled out anything suspension wise in my mind, and i am now thinking engine or gearbox mounts? am i in the right direction? I had the clutch replaced about 2 months ago with no issues after, but they will have removed the gearbox.

I took it to my garage on Monday, they tightened something on the front suspension, but the noise continued. Its going back next week, but wondered if anyone had any thoughts i could arm myself with.

Thanks

Nick
