Update: there are two screws at the top of part 2--above the speedometer at roughly 11 and 1 o'clock. After removing the screws, the squeak goes away. Not an elegant fix, but it isolated the noise.
I want to remove that part of the dash so I can see what's behind it. I'm wondering if adding some foam-rubber weatherstripping strategically to the back will make the squeak go away.
The problem is that I'm not sure how to remove that part. With the two screws removed, I can tip it forward, but I can't quite remove it. I'm just hesitant to force it in case there are additional screws I can't see--I don't want to fix the squeak by breaking the dash!
Does anyone have any experience in disassembling the Forester's dash?
