Time To Refine

[seduced]

^awesome. Let us know, I have a feeling there wont be a big difference due to the boot lining not being "heavy" enough to absorb sound. But it certainly can't help.

Once I get the diff/tailshaft vibrations sorted on my car, this process will begin. Dynamat X-treme will be on order!

Tomorrow I am driving from Melbourne to Sydney, I have been waiting for this drive to see how my slow bit-by-bit fixing of little random bits and issues would fare up on a long drive!

Last time I did this drive was in a NL Fairlane By Tickford, it was very comfortable, very quiet and the only complaint was stereo wasn't nice enough to enjoy my CDs lol..

I am interested to see how this rubber boot liner goes, too. As mentioned, it cannot hurt and would help me keep my boot carpet spotless

The glovebox is something I have been meaning to tackle just like you have, I also plan to add material on the inside of the box so that things don't thump/clunk/vibrate along he road or over bumps.

I have access to a bit of the same material used on the back of FPV seats, so I will try and match it up with the subtly colored suede and see how it goes.

I just turn the music up, works a treat.

I know Rolls Royce used to put leather under the wheel arch to stop noise from stones being flicked up from the tyres on dirt roads. Have fun and good luck with it all.

In the BA/BF series fitted with the fold down rear seat armrest, when the arm rest is in use, a thin elasticized fabric barrier is all separates the boot from the cabin; in my car this is 99% of the time.

Blocking the arm rest cavity and hence somewhat isolating the boot space, is therefore potentially a means of chasing down some NVH improvements, although, complete isolation of these spaces would require serious work around the split fold seat system.

One simple way to block the cavity when the armrest is in use, is to fashion a cushion or a plug, which makes a tight fit into the cavity.

So as not to appear out of place, the cushion covering would ideally closely match the style and material of the existing upholstery. When not in use, the cushion/plug could serve as a normal cushion.

Memory foam would provide a decent acoustic density and edge sealing capability for this application.

I have spoken to a well known motor trimmer about fashioning such a cushion, in leather to match the existing cabin leather, and the project seems quite a low cost option for potential NVH improvements.

Some, but not all, of the the dimensions of the plug could be taken off the arm rest itself. (the armrest plugs the cavity when retracted) The armrest partially occupies the cavity even when lowered, so any dimensions taken from the arm rest would to be modified for use as a plug.

Thanks AA. That something else to add to the list. However, I will be doing a full deaden of the entire boot, hopefully this will reduce the noise enough. Whenever I have rear passengers, the arm rest is down. I've noticed the noise as well...

Anyone know the best place to buy Dynamat X-treme bulk packs for a decent pricE?

Fantastic response Daniel! That information is gold to me. I'm honestly glad someone else has this OCD-ish obsession with finding rattles and improving the overall feel and quality of the car.

Yes... Daniel is an anal so and so.. I remember one of his previous Fairlanes... The rear seat carpet would still fluff up like it did when it was new, even though the car was near 10 years old. Immaculate wasn't a good enough word to describe how he keeps his cars.

Either I'm lucky or there is something different with my car, as I have no noises out of the ordinary. I did a 7000km trek from Melbourne to north Queensland and back, and there were no rattles, noises, droning that were annoying. And some of the roads I drove on were disgraceful.

There was the obviousy tire roar from the stocko Dunlops on coarse chip roads, and when the interior got really hot I'd get a very occasional creak from the passenger side of the dash I've never heard from again. Plus the thumps from the suspension over rough bumps in the road, but this is typical suspension/damper noise.

What I was ultimately wondering is if they do something extra with the Ghia's over the lower models. My car being a Force, based on a Ghia, and the Typhoon being based on an XR6T must have some differences, and I'd really like to get stuck into both models to see if this is the case.

For instance, the sound deadening under my carpet is all at least an inch thick high density foam, and it covers the entire floor.. Including the transmission tunnel from front to back. It's that thick you cant fold the carpet in 2.

The doors have a large foam blocks in the hollow cavities. I noticed my mates ute's dont have this (XR6T and Tornado).

The boot carpet has some foam under it in area's that sit on bare metal. I always make sure the spare wheel is strapped in f*ck off tight so it doesn't move or rattle.

The top side parcel shelf cover has sound deadening material glued to the entire underside of it. There is some bitumen/aluminium matting covering any large cavities in the parcel shelf. The underside parcel shelf cover again has a stack of sound deadening material glued to it, but I've seen XT's and XR's at the wreckers that have the cover, but no sound deadening.

I'm sure having heavier seats because of the motors and air bags help with vibration based noises. Rarely do I see the passenget side seat vibrate when going over rough roads.

I'd also guess having a lined glovebox helps a little... Along with the dicky glovebox opening piston that I'm guessing would apply some tension to the glovebox to stop it rattling.

Already got the boot lid liner, so cant say if there are any differences.

But mainly, what I have listed above, does a XR6T have the same in terms of sound deadening, etc... If not, then I'd assume Ford has already identified some short comings in the general NVH and applied fixes to the higher series models.

Of course rooted bushes or harder bushes will make a massive difference to how much noise is transferred into the cabin. The only way to fix that is to stick with the awesome factory rubber ones.

I can't complain about how noisy my car is in general driving. Not to say there are areas for improvements that might make it better again, so I'll too be watching this closely.

No way I can deny that Adrian haha, this car is no different and I have had the joy of owning it from new, too! That being said, this car has had more use than all my last cars put together.. PS, that carpet fluff happened in both f my Fairlanes and it drove me crazy seeing fluff laying on the floor lol!

Either I'm lucky or there is something different with my car, as I have no noises out of the ordinary. I did a 7000km trek from Melbourne to north Queensland and back, and there were no rattles, noises, droning that were annoying. And some of the roads I drove on were disgraceful.

You are def lucky ARM, my F6 was great from day 1, bar a small creak in the dash which I only just got rid of myself as they claimed "it is unfixable" and by this stage warranty was up! (arseclowns!) Also, just like you have noted, tyre roar is pretty bad with 19" rims and dunlops, getting some great tyres has helped a lot but other than that.. not too much we can do..

For instance, the sound deadening under my carpet is all at least an inch thick high density foam, and it covers the entire floor.. Including the transmission tunnel from front to back. It's that thick you cant fold the carpet in 2.

Mine is the same at least at the rear half of the cabin, I cant comment on the front as I am yet to play with the front.. I'm a little reluctant, still.

The doors have a large foam blocks in the hollow cavities. I noticed my mates ute's dont have this (XR6T and Tornado).

Unsure if I have these, I wish to do the doors soon, but not sure if the trims are going to be a pain to get on/off so I have left it for now. Will look soon however.

The boot carpet has some foam under it in area's that sit on bare metal. I always make sure the spare wheel is strapped in f*ck off tight so it doesn't move or rattle.

I too have these foam bits on the bottom of the boot carpet that covers the sides where the metal is in direct contact..

The top side parcel shelf cover has sound deadening material glued to the entire underside of it. There is some bitumen/aluminium matting covering any large cavities in the parcel shelf. The underside parcel shelf cover again has a stack of sound deadening material glued to it, but I've seen XT's and XR's at the wreckers that have the cover, but no sound deadening.

This too is the same, adding something suitable to the bottom of the parcel shelf after you remove the bottom cover helps a lot too.

I'd also guess having a lined glovebox helps a little... Along with the dicky glovebox opening piston that I'm guessing would apply some tension to the glovebox to stop it rattling.

I will line my glovebox tomorrow if things go to plan; I have access to a lot of the fabrics and cloth used in HSV/FPV cars, so should be able to get a nice match.

Already got the boot lid liner, so cant say if there are any differences.

Boot liner is also there, it isn't as good as the ones from the EL/NL range however, so I removed it and added some stuff behind to help.

But mainly, what I have listed above, does a XR6T have the same in terms of sound deadening, etc... If not, then I'd assume Ford has already identified some short comings in the general NVH and applied fixes to the higher series models.

I would love to know if there is anything they addressed over the run of the B series or in different models etc like you say.. If you find anything, let me/us know :D

The carpet in mine is very thick, however it doesnt go over the transmission tunnel. No deadening is on the parcel shelf, none in the boot, none in the doors. I will be applying DynaMat Xtreme to the boot, parcel shelf, doors, under the rear seat, transmission tunnel. I'll also apply body deadener to the topside of the wheel arches (just thin plastic covering) to try and soak up some noise as well. I'll also look at ways of reducing diff noise being transferred into the cabin by filling/deadening mounting points in the chassis.

I did have a win though. I have finally killed the dash creak for good!!!! Some high density foam was placed between the windscreen and dash at the firewall. I also managed to get some foam under the dash here as well. Fiddly tough job, but it worked well. There is now complete silence when cornering!!!

I will be strating the deaden process in the coming months. I just spent the Dynamat money on new tyres....

Hi guys..

As I promised, I set to lining my glovebox and putting something a bit thicker on the back just to aid absorb a little more of the sound coming from behind the box itself from the front of the car.

I have already noticed that things aren't rattling in my glovebox anymore which is a big plus; I cant say that the general noise from the front has been reduced significantly (no real surprise there) but it seems to have quietened things over bumps and also cut out a bit of noise when using the climate control..

All in all a worthwhile, cheap upgrade, something that FPV should of done from factory and will aid in the accumulative efforts to quieten down the interior.

Details:

- inside of glovebox has the same fabric suede that goes on the back of the FPV seats, stuck on with spray on adhesive from Bunnings/Spotlight (~$13 a can, enough for the glovebox) etc.

- back of glovebox has a section of thicker material stuck on, this is unseen when the glovebox is back in either the open or closed position but will aid in absorbing a bit of noise in the area behind the box.
