i was wondering if anyone else is having this problem. when riding alone the passenger side rattles when i'm going over bumps at speeds over 35mph or so. is there anything i can tighten up over there?

 

It's most likely your seat back bouncing around. Play with the angle and the seat fore/aft positioning.

 

Or check your spare tire to make sure the wingnut is secure, I had a very annoying rattle that sounded like it was coming from the passenger seat area that I could not figure out, xviper told me to check the spare tire and sure enough the wingnut that holds the spare down was loose, causing the rattle.

 

i have the same problem, i thought it was the seat hitting the back but i moved it up and i still here it. but when someone is sitting in the seat now i don't here it, go figure

 

had the same problem, moved the seat and its gone now

 

Also check if the passenger seat belt is hitting the plastic interior piece beside the seat back.

 

mine sounds like its coming from the door. any advice?

 

If I would post what rattles in my car, you would cry...

 

Its the seat belt! Just slot the metal thingy into the plastic guide of the seat belt or hook it in the lock.

 

I have adjusted the angle of the passengers seat and this often helps. I do have some rattles that seem to be coming from inside each door. I will check the seat belt next time though.
