Hi there, I've had a squeak coming from the back of my x type while driving and also when I push down on it. I've taken it to a garage where they have told me it's dry joints. They sprayed it with grease etc and told me to keep driving it and the grease will work it's way in. I've been back twice now and the noise is still there. It's embarrassing when I'm driving along. The mechanic looked underneath the car and says everything seems fine with everything else. Has anyone else experienced this problem?
