Haldex Pump best way to get it working

That’s interesting, there’s so much out there about Haldex but I still do t feel like I really know, Land Rover themselves aren’t interested in putting out technical spec like that, like someone else mentioned that never even put out a service schedule for the Haldex unit, I wonder why mine seized then, maybe just the age of it, it can’t hurt to engage sand every now and then even just to humour myself lol thanks for that

If I’m reading that info right on the Mk 1/2/3 Haldex it’s suggesting that under normal road conditions 10% power is transferred to the back wheels, so does that mean all be it a small amount, there is actually some drive action happening at the rear diff, it isn’t simply freewheeling

LR had a number of haldex 3 failures when the FL2 was first sold. This continued. Things did get betterer but there were still failures. The haldex 4 was betterer but still had some failures. At the same time all this was happening there were FL2 rear diff failures anorl. That's another story but the main problem was thought to be the bearing. Some suggest the bearing isn't man enough. LR did put a biggerer stronger bearing in there in a later version of the rear diff. Even with a haldex 4 and stronger later rear diff setup, yer can still get failures.

LR helped out with some of the repair costs but there was a lot of anger in the FL2 community over failures. Not all costs were covered for everyone and it was not always as easy to claim, as one would hope. Owners were sometimes facing partial or full cost of repair themselves, for what was a known problem. There's a lot of cr*p talked about this including theories of parts being made from cheese. The reality is things did get betterer but the problems were never completely solved. In a way it's kind of down to bad luck if it fails, when it fails.

The haldex filter will get blocked if you don't try to prevent it from happening. The chance of it failing can be reduced by changing the haldex oil and filter as the haldex pump fails if the filter gets blocked. There's different/separate oil in the rear diff anorl. The later stronger rear diff did have some failures anorl. I guess there will always be a number of failures for every part on a car. There's some support for the theory if one part (haldex or rear diff) fails, it's likely to cause the other to fail anorl. So you needed a haldex and rear diff repaired within a short mileage or at the same time. One failure linked to the other. There is also some support for the FL2 suffering haldex problems more than other vehicles using the same device. I don't have any comparative figures to back that up so can't confirm if it's true or not.

As for service schedules and LR not including a haldex oil and filter change on the service schedule... or not adding it to the service schedule at a later date... one can only speculate as to why it did or did not happen... as we don't know their thoughts on this.

I would NEVER suggest LR did not update the FL2 service schedule to include a haldex oil and filter change in order to avoid claims for repair/damage from owners who had to foot the bill themselves. But I have heard others in the FL2 community offer this theory.

I can confirm I will be changing my haldex oil and filter. Preventative maintenance to keep me Freelandering and my Freelander happy.

Loads of information there thanks for that, I must admit I still have it in my head that using the Haldex under full load every now and then is the way to keep it healthy along with of course servicing like you said, I did try the FL2 in Samd mode at the weekend, it’s the first time I’d ever used it and you can definitely feel a power push from the rear, I wasn’t keen on how long it holds the gears for (mines Auto) so o tried it in command shift which was a lot better, I was quite surprised just how much you can feel that push from behind though so I know it’s all working sweet, I’ll probably do this for short journeys 2-3 times a month
