HI guys , please excuse me now if this is either stupid or blatantly obvious but I have a rattle that is driving me nuts My 97 facelift 4l xj hasdeveloped a rattle ,it sounds like it is under the truck around the front seat area , and it kinda sounds like a heat sheild kind of tinny rattle , it doesn't go with the revs and gear changes but is only there when the car is in gear and moving , cant get it to rattle & be identified when back wheels are off the ground . Also rattles in 2 and 4 wheel drive .Any thoughts cos my radio won't go up loud enough cheers cully
