I have a 2010 Range Rover Sport. Recently the truck has developed a rattle that sounds like it is coming from the rear section of the sunroof assembly that sits over the second row seats. Has anyone dealt with that issue before? The sunroof works properly. I sounds like the rear guide assembly is loose. I may have to drop the headliner to inspect it. Any hints on dropping the headliner? Thanks
