Sealing a wagon tailgate

Hi everyone,

My grey matter seems to recall that there was a tech bulletin or the like by GMH that showed a wedge shaped piece of rubber that could be added to each top corner of the bottom tailgate that would provide a better seal.

Can anyone point me in the right direction?

G'day Stu,

When you fit these, can you take some photos please? I suspect I may need to do the same thing on the EK.

Cheers,
Harv

Dragging up an old thread.

As suspected back in 2016, I am going to need to fit these rubber pieces to the wagon tailgate. The recent wet weather has shown that it leaks like a sieve without them.

Does anyone have the dimensions of these bits, before I start trial and error?

Cheers,
Harv

I'm also extremely interested in this so would really like to see some photos and dimensions as Harv said.

Some investigations yesterday once it stopped raining.

The upper tailgate seal extensions would look similar to the blue PVC tape:

This meets the lower tailgate where the hipline comes across:

The lower tailgate seal has a thick bulge in this area:

I wonder if the original lower tailgate seals had no "bulge", and that GMH later modified them to include the bulge and hence not need upper extensions?

In any case, the bulge doesn't work too well... testing with a water can shows it is the bulge area that is leaking on mine. The bulge is thick, hard rubber, whilst the opening rubber that it seals against is soft foamy rubber. The soft foamy rubber gets mooshed around pretty badly.

Hoping someone will chime in with how the solved the problem, otherwise will start playing with making up some extensions.

Cheers,
Harv

Dragging this up again.

Purchases all new seals, same issue. Water all over the interior boot area. Image


Did anyone solve this?

I have some polymorphic plastic I can mock up a piece? Would be an easy mold to make

I got distracted (at times I have the attention span of a goldfish), and did not make up the GMH extension bits. My tailgate still leaks like a sieve, but a car cover keeps the majority of the problem at bay.
