Thanks I have jacked the car up removed the wheel a couple of times to check to see if anything was loose or making a noise and I've herd people saying about the lug nuts so I've double checked them. Now it's to the point my torque wrench is living in my boot and I have checked them about 20 times in the last couple of weeks lol also removed everything from the boot. I didn't even think there were any 3.38 lsd diffs out there ? Now I'm hoping I have one lol. What car did they come on ?
