Here are some photos of my van.
I think what I will do first it is to put the part apart and see how is the inside of it, as two of the links you guys have sent seem like it is the part but they are different inside!
As soon as I have the picture of the inside I will also to post it!
Once again thank you very much for the help as we getting closer!

 

Holy smokes, that thing is HUGE.

 

yes, it is, 6,5m length!
the consumptions in gas is crazy for Europe!
but I just love the feeling I have when I drive it!

 

Have you considered an LPG conversion??

 

When I saw the front and rear axles on the tag, I suspected it was an extended van.

The rotors are an assembly, but keep in mind the bearings and bearing races are replaceable.

 

I think they generally come with the outer races installed, maybe.... (who knows in this day and age of 'cheap as we can make 'em'....) Replacing the bearings probably wouldn't be a bad idea in any event.
