Keen to do something to my Landcruiser as the noise is starting to get to me a bit. Anyone have experience in this field! I'm really looking for a cheap, cost efficient way of making an improvement. Cheers

Well firstly, a good evaluation of what you already have is needed. I found in the morry minors that the best thing you can do is put a good heavy underfelt under the carpet, that got most of it. If you already have that then It may be a case of buying a dynamat bulk pack and covering as many of the large panels susceptable to vibration as you can. Good air sealing from the underside and engine compartment is a must.

Cheap = domestic carpet underlay
Proper automotive sound deadening isn't cheap, but it is much better if you get the interior of the vehicle damp

I think the most noise is coming from the transmission (seems a bit worn out) and the tyres. I would probably target the tunnel through the cab 1st and then around the wheels. Is it worth importing dynamat myself and getting it cheaper!

dynamat is quite heavy stuff so don't let shipping catch you out if you do buy overseas.

q-mat is a cheaper alternative. Supposedly as good.

There are a few products that are virtually the same. Dynamat is not cheap, but I have used something that I got off TM, looked identical. apart from the brand name. Work out how much you might need, and go by the per square meter cost, as some packs are more expensive, for less product. I've done the front half of my floorpan with Dynamat, as it was the best option at the time. Made a huge difference.

I have sound deadened a few vehicles and found by stripping out all the carpet / underlay / coating metal with brush on underseal / replace underlay with the domestic rubber underlay / carpet on top does a very effective job.
NB = Be liberal with the underseal.do not use the spray on.

If this is a car you will EVER do any panel work on I'd say don't do this. Effective maybe, but a nightmare to remove.

Why the hell would you want to remove it as a car owner!

Well, as mentioned in my post, panel work.
