Stop a rattle from rear of Vauxhall Meriva particularly when at slow speeds and cornering query suspension?

this sounds like the rear bushes have worn or possible totally failed , you may also notice a small amount of play on the back end of the car while cornering , parts should cost between £20-£30 and take around 2half hours doing it yourself , or in garage on on a lift you shouldn't be payin for more than 90mins labour !!!
