Haldex Test

Is there a test (apart from getting stuck in muddy field) that you can perform to test that the four wheel drive (haldex) is working properly on a freelander 2? I recently got stuck in soft ground pulling a trailer and noticed that the rear drivers side wheel had lost traction and spun as I accelerated. The passenger rear did nothing? I disconnected the trailer but still had to get towed out as it wouldn't budge!

Would this come up as a fault in the freelander's stored memory? It was recently in with a landrover specialist and he never mentioned an error?

Any advice appreciated.

Geoff

I am sure that I have read on here and if memory serves me right there's also a video that you have to gently accelerate and keep doing so so the abs and other stuff takes over and puts power to the wheels not driving

The haldex connects the rear axle to the rest of the transmission - if a rear wheel is spinning then the haldex is engaged.
I think that the haldex is also always engaged if the car is doing less than 18mph, ie when setting off.
If only one wheel spins, there is a problem, if a wheel spins then the ABS is used to brake that wheel, thus sending the power to the other wheel on that axle. Tangiers Orange - gone, missing her

Thanks for your responses on this issue. Would a diagnostic test show up errors with it do you know? In sand mode it says it splits the power 50:50. I think i'll stick it up on four jack stands tomorrow to see it that's working - failing that I bring back to local specialist to see what he thinks. We live up in the mountains so 4 x 4 is badly need when weather turns bad Cheers, Geoff

Really easy test

apply full lock when stationary, set off like a teenager, if rear axle is not connected to rest of transmission one of the front wheels will spin.
Rear axle might not be connected due to haldex failure, or due to front reduction box failure.

For this test you do not need to be in any special mode as the rear axle is always connected when setting off from stationary.

Edit
If front transfer box has failed, no faults will be logged - but the propshaft will not rotate, so easy to spot.
I suspect that the haldex is working as a rear wheel was spinning. I also suspect that the traction control is not working, as it should have braked the spinning wheel - this should show a fault code. Tangiers Orange - gone, missing her

Couldn't wait!!!! Took it down to the bottom of road (quiet section) put it on full lock and floored it. Loads o front wheel spin alright so further investigation required to see what the culprit is!

Note that with special programs off the Haldex disconnects the rear when there's significant steering lock on. This is to prevent transmission wind-up and potential damage to the transmission when starting off on high-grip surfaces.

With a special program selected the Haldex will remain engaged, but personally I'd be wary of a test like this on tarmac as there is the potential to damage the transmission.

The abs and other stuff will only take over if you have the engine rev's above 1800. Then the special programs kick in and the abs locks the spinning wheel to transfer the power to the none spinning wheel. Have a look at the link. https://youtu.be/V1taiNf2BHs

Bit primitive suggestion....

With the front end jacked on a PAIR of trolley jacks sitting PARRELEL with the wheels and the car on a FLAT surface, engage first gear and VERY GENTLY key the clutch out.

If the front wheels spin it is disengaged and if the vehicle offers or does move forward it is all ok!

People will say this is a bit rough which it is a bit, but if the trolley jacks are parrelel with the car wheels and you are on a level surface they will roll rather than twist.

Not only can I remember them but I can also recall when they took over from horses in the 50's. Sad 3 x FL1 2 manual + 1 auto

I wasn't even a dirty thought yorkie! Rolling with laughter

But is that a scammel coupling because I have seen one before if it is?

Thanks for that guys I'm going to bring it to a tyre centre (lift that picks it up from jack points) and try that. Hopefully I'm imaging things but I have my suspicions that it's donald ducked. Am I also right in saying that if I stick it into sand mode while it's up there that the 4 x 4 drive should hopefully engage?
