so goes to clean my wheels today; what harm can that do?
well not sure but it looks like either the strut cap or top mount (they the same) has decided it likes the spring very much and is resting against it

get a loud twanging noise when turning and the sound of something loose when going over bumps. frightened the life out of me when it first went bang!
Car still feels fine to drive though so hopefully Alan in work can have a look tomorrow.
I won't be taking my wheels off to clean them again!!
