help diagnosing noise

[Ex-User (60778)]

There is a knock/creak coming from the left rear. I've had the noises for 2months now.
Its not a scrapping sound, definitely more of a creek than a knock.
Today though when I was putting my rear seats back in, I stripped down all the interior plastics from the rear and went for a drive. The noise was still there.
I gave the rear tyre a good shake (car was on the ground not jacked up) and there was a creak from behind the centre of the wheel, sounded like the hub or towards the bottom of the shock. I first thought top mounts due to how loud the noise is inside the car but now obviously it isn't

Probably your shock.

Well the shock isn't leaking, no cracks in the spring. As I said, if you shake the wheel on the ground there is a creak coming from the centre of the hub. Could this be worn rear suspension bushes? Rather not replace the shocks if I don't need to
