I've read about it, but not seen much. I've got an odd rattle at start up and sometimes at idle at a stop light. It's not very loud or hard sounding (if that makes sense). It sounds like it's muffled, so I'm wondering if it's the flexplate.

I've read that the bolts come loose, and that there is an access panel at the bell housing you can open to tighten. I've also read that you can bump the starter to turn the motor over to hit all the bolts. I'm wondering if I can remove the spark plugs and use a 3/4 breaker bar to turn the motor over to check the flexplate bolts. Also, how many are there? This is on my 97 4.0 AW4.
