Hello! I just got my very first 4x4 :)

I was awere that 4x4 is not engaging when I was buying it - it's time to fix that. I've seen topic about troubleshuting flashing 4wd light and found an issue. I have no  vacum hoses at all :'D It seems I need to rebuild it more or less. I found this under the bonet - so it seems not whole system is missing.

Does any good soul has some photos how it should be connected? Diagrams are not very easy to read when I assume that everything might be messed up.

Here you go.



Normally the pipes are routed down to the chassis and along the radius arm to the front axle, but this route is quite exposed. I prefer to route the around the engine bay then down the brake hoses to the axle, so they are out of harms way.
You will need about 10m of 4mm id (inside diamter) hose and 2 T pieces. I use clear pvc hose because it's cheap.

Much thanks! You think I can get away just installing flexible, rubber hoses and securing it?

Just out of curiosity what do the centre caps of your front wheels look like, are they black and flattish or do they have a sort of handle or dial mechanism in them? I just find it odd that the pipes would have been removed unless manual hubs are replacing the vacuum ones.

Good point. They may also be black and flattish with a bolt head sticking out, where someone has used my quick and dirty hub locking method. Of they could have locked the vac hubs internally and you won't know unless you take them off.

It seems that maybe someone tried to replace whole system but ended up with "nah, I actually don't need 4x4". There is loop between lock/unlock ports (at least it was not sucking dirt), none of those alu pipes, rubber pipes closest to hubs are also missing (but plugs are not secured, so I guess I will have to clean those inside).

It seems those are original, vacuum hubs - no any kind of handle.
