Hi,

I need some tips to reduce vibration noises in Golf Cab 1989...

On doors:

- I have applyied a vibrational damper to the outer door skin.

- I have fitted an absorbent product behind the speakers

- I have filled holes with a adhesive damper product

- I have applyied a vibrational damper to the inner door skin.

Trunk and roofs

- I have applyied a vibrational damper and an isolator product.

I have done another tasks on trim panels, license plate... using polyurethane foam and urethane seam sealer.

On interior body, vibration noises have been halved but I don't know how to reduce the noises prompted by metal framework of top cover.

Some idea???

Sorry for my poor english.

Thanks in advance

Both Adrian and azbass have VW's and they might be able to help.

i've never looked very carefully at a mk1 cabrio. but i suspect the framework has some joints. and like umbrella's (sp???) those aren't very tight and vibrate.

dad owned a 2 door GTD mk1 but i can't remember too much regarding the interior. i really want to get that car back. it's solid as a brick.

I have used polyfil to fill an area that couldn't be silenced, packing as much as possible into the space. Which is an attempt to stress the offending panel into silence.

Great Stuff expanding foam is ghetto-fabulous

My rear doors on my yukon would flex like god knows, so I put around 10 cans of that junk in there, and now they don't flex 1 bit. They move on the hinges, but that's something different. I had a mustang gt with vibrating trunk and tailights. You can add layers of sound deadener, but filling in the large gaps and corners (especially the entire trunk lid) with great stuff made it like a brick sh*+house. It's about $5 a can, and makes an enormous difference for vibrations.

I'm not familiar with the car in question, but if it's a corner no one will see, add a can or two and see if it doesn't make a difference. If not you can always just cut it right out.

First thing you need to do is identify the source of the rattles or vibrations . Makes fixing a lot easier when you know what's going on.

agree with all the above, and one question,

Tej- did u keep window functions?? and if so how??

I was wondering the same thing.

I use Great Stuff too. I have 2 cans waiting around until I get the install done so I can kill some rattlers.
