You have to remove the plastic trim around the switch assy's and the knob for the lock. There is a bolt under the plastic trim...
You then pull up and it will come off.
The rattle is from the wood. It has small nuts to hold it on from the rear. They loosen over time. Just use a small amount of blue loctite on the nuts and GENTLY sench them down.
