knocking sound help
 

got a classic turbo and have just had some second hand wrx shocks fitted for the MOT,since i've had the car back when i go over a bump of any sort it makes a sort of metal clunking/knocking noise from the front passanger side of the car,any ideas what this could be,suspecting that there's something faulty with the second hand shocks but just wandering if anyone had any thoughts on it first,cheers
