thanks for the advice
i have just sprayed the top and bottom of the spring, i will give it all night to work its way in, i will see if that has done the trick in the morning, if not then i may just take it back to the person who fitted the spring and get him to put it back on the ramp and have a good look around to make sure it's alright under there.
i may get him to turn the spring a bit to see if that helps
