Huh, no idea. Like I said, I'm a newb. What should I look for?
well, if you have a wiper on your rear window, then you have a rear wiper motor...hehe.
1. Remove the interior panel off the hatch
2. Tighten wiper motor bolts (if applicable)
3. Tighten latch bolts for both locking mechanism and the door handle.
4. Drive it around and see if you still have the rattle.
4a. If no rattle, re-attach interior panel and repeat Step 4. If it rattles, then your panel is the culprit
5. Look at your exhaust pipe at the rear of the vehicle and follow it along, inspecting it for rubbing the passenger side leaf spring at any location.
6. Look at your leaf spring bushings and make sure the leaf spring loops arent hitting the unibody buckets (where the leaf springs attach). If the leaf springs are loosing their bushings, it will cause rattles when the spring hits the mounting boxes.
7. Check to see if you rear seat is rattling. Lay it forward to see if it stops.
8. Check for loose speakers.
9. Check for loose wingnut on the factory tire carrier
Hopefully that will cover most of the possibilities.
