Does anyone know what's inside the rear hatch on a WRX wagon?

[BD]

Hey, all.

I'm considering sticking some expanding foam in the space between the
felt 'liner' of my 02 WRX wagon rear door and the door itself. I have a
large stereo subwoofer in the back, and _something_ in there is
rattling. I think it's some of the wiring tapping against the metal of
the door.

I'm considering several options, including stuffing some small blocks
of soft foam in the space to press the wiring in place, or perhaps even
using some of that expanding spray foam.

I don't think there are any 'moving' parts in there, just wiring. So I
don't think there's much risk of problems if I gently pack some foam in
that space.

Does anyone agree/disagree??

Thanks!!

In my 95 Legacy, there are a couple of rods that link the hatch keylock
mechanism to the latch mechanism. If I filled it with foam I wouldn't be
able to lock/unlock the hatch anymore.

Mm. I expect I should be seeing the same thing. Perhaps covering those
rods with some kind of half-pipe before sticking the foam in will be
enough.

Or, I guess I could use small foam blocks and simply target the areas
that have obvious bits of wiring...

the rods tend to rattle after a few years in the rodd end clips. consider just placing some soft foam between them and the door to remove the tendency to vibrate. light pressure will not affect the mechanical movement of those rods
