What's the sound coming from my suspension? (Video + Audio)

Any ideas? I've sat under the car while my girlfriend jumps up and down on the truck but I can't pinpoint it (& she weighs 45kgs so barely moves it).

I suspect it's coming from the lower r/h frame in the video (feel a slight vibration there when it's making the sound). Took the wheel off and jacked the suspension but couldn't replicate it. Greased all the bushes to death and no change.

Girlfriend asked the WOF guy but it sounds like he had no idea / wasn't interested.

Could it be anything dangerious (very loud while driving)?

I've had limited success tracking down sounds myself... It's not something like the spring rubbing?

Keep filming till you find the loudest place?

Dry ball joint?

Does it creak when driving and turning?

i want to say ball joint(s) too.

its been a while since i worked on one of those but i seem to recall the pair (upper and lower) being easily replaced.

Yes! Even turning while parked it makes that sound. A ball joint would make sense - Is there any way I can definitavely know for sure? I understand dry bushes can make a similar sound (I sprayed a tonne of WD40 on them in the hope it might queiten them & tell me where the problem is - but nothing).

It's quite noticable when driving and going over bumps. Seems to be getting louder / worse by the day.

Given everything mechanic's probably going to be closed for the next few weeks I might have to have a crack at fixing it myself.

Just to close off this thread: one very stuffed lower ball joint.

I asked the mechanic to replace the top while he was in there and apparently it wasn't in much better condition.

Still surprised there was no play in the wheel, especially given how bad the joint apparently was. But no more annoying sounds which is a relief.

There was no play because torsion bars where pre-loading them (via top ball joint). I seen similar failure in hiaces: the ball joint are completely stuffed, yet no play until you unbolt it...
