P38 - Rear, driverside, squeak!

Ok chaps/chapesses ideas please! My P38 has developed a low speed squeak from the driverside rear in the last couple of days.

Strangely although it can only be heard at low speeds, it is not speed dependent in pitch or frequency, e.g. it doesn't get higher the faster you go, which is what I would expect from bearing or crap stuck in brakes, and props were recently checked and greased. It just stays the same, which would suggest it's not drivetrain related. However if it's suspension it shouldn't really be rythmic.

Any ideas, that don't include matches, gratefully received....

Don't be cruel, let the missus sit in the front, just make her promise to be quiet.

Datatek, great minds think alike!!! - but they do say fools seldom differ!!!! I find turning the radio up tends to eleviate all sqeeks and rattles

I had the same it was the bushes on the shocks and of course a bit of gaffer tape on the missus gob might have helped

only worry about rattles when they stop... means what ever was rattling has fallen off !!
