However, today it's been really bad and it sounded pretty bad too I was parking up and noticed a sheared bolt was on the drive. I jacked up the rear couldn't see any issues there but at the front of the propshaft are some missing bolts:

I don't know the name for this part, but is it just a case of buying new bolts and fitting them - what dimensions will I need? Will there be any underlying damage?
Thanks for any help
