passenger side rattles when i go over bumps but nothing seams lose. any ideas

...but it happened to me as well and my brother used a spray lube on all of the mechanical roof joints and it went away. I will asked him about the specifics next time I see him. Since then it has gone away...

There is a thread on how to tighten some of the bolts in the roof mechanism to make this issue go away.
