it does still squeak abit, not as much. i took it in yesterday to have a new engine breather unit put in/on, as the engine light came on.
i got them to re check the squeak.
they said its definatley right side rear ( looking at the back), but couldn't pin point it.
so they just pumped a loadf of grease into the joints/bushes etc.
it seems to have cured it for the moment.it may last a couple of days, or months, we'll have to see.
but it seems like a quick and cheap fix for now.
i hope this helps
