So quick and simple yet magical... eliminated all the rattle / crackling from the A-Pillar. (That sound you hear that seems to come from the windshield area on both driver and passenger sides.)

Procedure is the same for Driver and Passenger Side

Time: 15-20min
Tools Needed
-Flathead or Nylon Pry Bar (leaves less marks on plastic)
-Phillips head or 10mm socket wrench
-Foam Tape (some people use felt tape)

Another good door rattle fix here:
http://www.iwsti.com/forums/diy-mods-installations/257820-door-panel-speaker-rattle-fix.html#post3831385


WARNING!!
DO WHEN TEMPERATURE IS WARM (50+degreesF). plastic is brittle when cold.
Note: I did it when it was 32F out, but warmed the car and put the heat on the pillars to be safe.

Foam Tape I used. A little too thick, but Its what I had laying around.


1. Use flat head to remove the Pillar Cap. (once you popped the bottom off enough, you can just use your hands.)


2. Unscrew using Phillips or 10mm socket. Pull towards middle of car to remove hidden clip in center of pillar.


3. Slide out the A-Pillar.


4. Remove the cheap tape that subaru puts on the tabs so you can put your own tape.


5.Cut up some of your foam tape and apply it to the tabs. Use whole pieces that wrap around the tabs *preferable*
(picture shows small cut up pieces *not-preferable*)
Note: I used really thick foam tape because I had it laying around



6. Reverse Steps 1-3.

Posting to say that I did this a while ago and it really really is worth the time. I had some rolls of Velcro hanging around and just used the "soft" side with adhesive backing.

Yep, I did a search, and couldn't find a DIY on it, so I decided to write a quick one up. DEFINITELY worth it.

Good quick write up :tup:

I've heard new vibrations since I installed my motor mounts, all happens <2k RPMs
Is this only an issue with GR's?

i'm sure the older models will rattle too. not sure if its exactly the same method. but you could try and pull it out and check.

Did this today with some foam tape that was similar to what you used. No rattles on my test drive but it was 60ish degrees outside, so I will know for sure if it worked if I don't get rattles on the way to work tomorrow morning. BTW that phillips head screw was really tight on my car and I couldn't get it to turn with a screwdriver. Using a 10mm socket will work too for those who have the same problem.

thanks, updated the writeup to include the 10mm socket. mine used to rattle even in the warm. its so much better now.

I haven't heard this rattle yet, but great write-up and pics nonetheless. At least I know what to try now if I do start hearing it.

Just did the 1/8" thick x 1/4" wide closed cell foam to a-pillar trim trick on 2011 wrx. Easy to do. 15 minutes per pillar and one $3 roll of foam was plenty. Did tabs at base of trim as well as where trim contacts dash and window. Also did a few wraps on wires running up next to metal. No more rattle corner dash rattle in cold weather.

ahhhh I hope this is the rattle I have. I keep hearing a rattle in the windshield area but I couldn't isolate where exactly. I'll be driving along and randomly attempting to put pressure on various panels to see if I can make it stop temporarily.. driving me nuts. worth the time and effort to see!

Great permant fix. As a temporary fix I had a piece of Velcro lying around and wedged it into the groove between the bottom of the A pillar and the dash. Seems to be working thus far for me. Downside is you can see the top of the Velcro slightly.
