Thanks for the info. Where did you find this information though Gorilla?

Hi,

Ac427- there was a ''Class Action'' in
North Amrecia due to multipile complaints
which kicked all this off.

This information was posted by one
of those involved in that action, who
apparently had the repair works carried out.

Regards,

The Gorilla.

Mr Gorilla

What's your opinion on doing this structural and cavity foam as a preventative measure? i.e. still inject it even when there are no cracks appearing?

I've seen the 'foam' in person and it's actually not a foam - rather a very hard structural epoxy that hardens without expansion - I have also seen the proceedure performed on two cars already and it isn't a large surgery per se ... and the amount of product injected into the cavity is actually quite minor.

Would like to hear your feedback on this.

Not much to it really (great DIY from the person below):

Hi,

NZ_M3- I believe your absolutely correct.

The injection of the Resin would bond the
two metal layers together making for a
lamination of the two skins around
the subframe mounts.

This would then not only spread the load
via the new ''lamination'', but it would
also absorb the 'sawing' or 'tearing'
motion across both skins around the
load points of the subframe mounts
on what was just a single skin.

There are 2 part resins that can be injected
via a hand operated resin gun,
which with a couple of small holes in the
correct places would make this a very simple
but very effective proceedure.

Also with the correct resin it would also still
allow the Sub Frame bolts to be removed
when required so it could be undertaken
with the subframe in-situ, more than likely from
above the boot floor as opposed from underneath.

Regards,

The Gorilla.
