Hi, i recently bought a 3door cosworth. which comes with a bit of work, For instance when i release the clutch, i hear often a rather disdurbing knocking sound from the rear/underneath of the car. So i went out checking, the rear beam is suspended in nylon bushes so that couldn't be it. However i find that there is a lot of play on the propshaft bush. Is that normal? Is that easy to replace? (or do i need to buy a whole new propshaft?) And do they wear out often?

regards, istvan
