Vibration noise when in Drive - mount gone?

[John87]

Hi folks, this is my first post, having been a long time lurker so my apologies!

I've recently bought this 2002 C70 2.0lpt as a fixer-upper and have already done quite a bit of work to her.. New PCV kit, steering rack, from calipers etc however this one has me puzzled!

I hear this droning vibration through the bulkhead when I am in Drive, either when accelerating hard or sitting idle with my foot on the brake. I've already replaced the upper and lower torque mounts (upper one was shot) but it's made no difference.

The noise disappears when there is no forward acceleration (therefore doesn't happen when in reverse or coasting). I've included a YouTube link of the symptom below..

Can anyone relate their experiences or suggest something else I may have to replace?

Thank you!
