hi all , I have owned my s type for just under a year and whilst very happy with it , I do have a couple of issues which hopefully someone could help with.... 1. do the front of the headlamps come off easily to effect repair to the headlamp adjustment unit and 2 ... having replaced both front struts and springs I am still getting a knocking noise from under the car when going over bumpy roads , whilst I had the car in the air I checked all the other suspension parts for wear and movement and all seemed ok , they were all lubricated at the same time , so I am now at a loss ... thanks in advance for your help.
