There have been a few threads on this. Squeaks are 9 times out of 10 rubber rubbing on metal. Your best bet is to rock the FJ while a friend pinpoints exactly where the noise is coming from. Then, see if it is something that can be adjusted, if not, silicone spray will resolve the noise for sometime but may not be a permanent fix.
Someone recently posted a thread almost with the same problem. I don't recall what the outcome was though.
Good luck!
