Hi All

For a while now my rear suspension has been squeeking like mad, there are two noises, a creaking noise, and a high pitch noise, but both coming from the same area at the rear. it disappears if I have passengers in the back though, obviously as what ever it is has less room to move about.
I've got a mate that used to be a mechanic but hasnt looked at it, he thinks it could be new bushes or dampeners?

Does anyone know how much this is likely to cost? rang a garage and they said they will come for a drive with me tomorrow.
