hi guys, I know LR put the newer haldex onto the 2009, but the car I am getting was reg'd in Jan 2009.. I can do a vin check, but where did the new haldex come in?

Edit: dont bother reading any more of this thread, I forgot that it had already been covered : )

I've answered to your (same) question here...

Look at the digit before the "H". If it reads 9, or later, you have Gen. 4 of Haldex. If it reads 8, or earlier, you have Gen. 3.

nice one Alex, as always you prove to be the tech guru : )

Or, to be sure, look under your car and see the housing of the Haldex pump as seen on below picture.
If it's a regular plastic covered cylinder as in the left picture, it's Gen. 3.
If it has a metal end protuberance, like on the right picture, it's Gen. 4.

Thankyou very much Alex, should you ever need to travel through sweden, my door, and my toolbox stand ajar : )

Pardon my ignorance, but does anyone know the reason for the change on design? Cuatro Por Cuatro

Thank you for the detailed information alex_pescaru and EYorkshire Cuatro Por Cuatro

Can I put a Haldex 3 instead of a Haldex 4?
And is iT possible that the H4 looks like a H1? www.freelanderclub.be

LR and some people have put H4 (so newer) in place of a H3 (older) and not viceversa....

I don't believe H4 looks like H1 because the internals are completely different...
Look here: http://www.awdwiki.com/en/haldex/

thanks!
My mistake, i thougt there was a H1 also in a FL2.


An other question:
- if you turn manually on the haldex, will the gears (? is it correct?) in de rear diff turn? Because I removed my 2006 FL2 halfdex en rear diff, and if I turn on the wheel of the Haldex (looks like a H4), the gears inside always turn. I have a an other one, seems to be a H3. If I turn here on the wheel of the haldex, the gears doesn't turn round. www.freelanderclub.be

That was so they could hide the Haldex gauze filter right under the prop shaft attachment and make you have to take that off before you can clean the gauze filter in normal maintenance. They had forgotten to make this as awkward as possible on the original design.

Naturally, it is incredibly difficult to undo the bolt requiring a vice and a large breaker bar plus some mild swearing.

JensV, first look at the picture I posted in the 4th message in this thread and identify exactly which Haldex version you have.
Then, as H3 has been installed until MY2009 and yours is a MY2007, if you have a H4 it means the car has been modified to accept a H4 instead of H3 and you should look for that kind of H4.
