foam / sponge in bottom of front A pillar ?

Post by Just_Kitt »

Just re-doing my underseal round the wheel aches and came across some foam / sponge filling to bottom of the front pillars (both sides) of the van that I have never noticed before - its soaking wet on one side and I worry leaving it there will lead to some nasty rust! - anyone know why this is there (it looks original) and if there is any replacement advice to stop it gathering water and leading to rust?

those sponges are part of the wind noise reduction kit

You can replece them with something more water resistant like closed-cell foam

Get rid if I where you and just use a thick underseal as a noise reducer...as long as the spot where they are is solid metal and not crumbling rust.

As always you guys have answered a question that there is no trace of on the rest of the internet! - Noise reduction makes a lot of sense originally - however my dude sounds like a beast whiles driving any way with its engine conversion - not sure 2 little bits of foam are really gonna make any noticeable difference!!!

So long as they are not important for any other reson, thats cool. I'll rip them out and underseal the hell out of the area - luck for us the A pilla only has a bit of surface rust around the wet foam and is still nice and solid

just had a look at both my vans and can't see this, perhaps it was a caravelle thing?

I assume you would see it here?

There's a good thread or two on the samba about the a post foam. It's s good road noise deadener. Some closed cell foam used in packing, cut to size with a knife and jammed up does a good job. If you take out the indicator housings, you get top and bottom access :-)

Thanks for the advice and pic - I think I might go for a bit of a road trip first and see If I can live with the noise before I add any new foam in there! - Mine defiantly had the full noise proofing package installed looking at the T3-infos site, but I can't say I would have ever called it a 'low road noise' bus!

I have a new body on my bus and I don't think these are fitted.
I do have a new tin of building foam though.........

Seriously though, has anybody retro-fitted the rubber seals that go between the door and the A column?
I have a pair in the barn but the body is different, it does not have the two raised areas for two of the feet.

Yes I did it.
you can bend those feet a bit and use a long screwdriver to screw the self tapers in.

Hello All,

Bit of an update - after a trip to Scotland and back, not having the foam was definitely noticeable, especially at speeds over 60! I have now filled the gaps with plastic packing foam - fingers crossed this wont hold water like the old stuff!
