Just a question about the Haldex couplings used by Land Rover. My old XC90 had the Haldex coupling but it wasn't full time 4wd but sent the power on to the rears if it felt the front wheels slipping. As I still possess a C30 Volvo I look in on the Volvo forums from time to time and there's a rapidly rising amount of members there finding out that when they need it, the AWD doesn't work. General consensus is that the angle gear splines strip out and the repair bills seem to vary from hundreds into the thousands to fix it. I was told the the RRS uses the same coupling for its 4x4 as the Volvo by a member over there but cant see it if its permanent in the Sport as opposed to "on demand"! Any of the longer term Sport owners ever had this problem?? Again I was told by a "learned" member on VOC that this is common on the Sport too. As an add on to this, my other half has a "W" plate Audi tt Quattro and the other night I noticed the front wheels spinning in the snow outside the house while the offside rear,(the only wheel I could see) remained stationary. Seemingly Audi use the same 4 wheel drive coupling too. Anyone with a bit of Audi knowledge know if the fronts should spin while the rears dont?? Or could this mean that quattro is now a front wheel drive like a lot of the Volvos are becomming?

Any help/pointers would be appreciated?

Cheers

I know how it works but how to put it in words briefly is not easy! 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

I know how it works. Its the incidence of them failing in the Sport as I've never found a thread on it!

On the XC90 especially it seems to be an almost daily occurence of new ones appearing! Not high mileage/older models either! Some are as low as 40-50000 miles!

Some are having to replace not only the spline shaft but the entire angle gear! One guy was told the whole auto gearbox needed changed at a cost of around 5k!

If its just the new redesign shaft its 85 quid for the part! Mind you with a redesigned shaft Volvo still have "never heard of the problem"!

Just being told that the failure is as common on LR models using Haldex yet I've not found anything is a bit of a niggling worry! Current, M135i in Estoril Blue with more extras than the cast of Ben Hur.

It is not a common problem on Land Rovers since the Freelander1 when LR learned a lot about the coupling and did some huge rethinking about them ( I suppose they never bothered to share the info with Volvo )
First thing LR found was that despite the Haldex Clutch being "sealed for life" the fluid needs to be changed every 3 years irrespective of miles as it degrades and looses it's viscous properties. The main failures were because on the first Freeelanders (R and S plate) they got the gearing wrong in the IRD which damaged the VC and also gave extremely rapid and very uneven tyre wear on the rear tyres ( a lady friend of mine went through a set of tyres every 2000 miles but LR acknowledged that problem and replaced them every time for free until they had sussed out the problem). I suspect that many of the Volvos and Audi which have an apparrent lack of 4WD need to have the fluid in the coupling changed. 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Funny you mentioning tyre wear! That's another HUGE bugbear with the XCs! Killing the shoulders in as little as 5000 miles and Debs barely got a year out of 4 tyres too! At least I can feel secure knowing I'm not likely to have a 2wd Sport sometime in the future! Current, M135i in Estoril Blue with more extras than the cast of Ben Hur.

Don't think the RRS uses a similar system.....

Land Rover is listed on Haldex website as a user of the hydraulic AWD systems along with VW, Skoda(wtf), Audi etc. Current, M135i in Estoril Blue with more extras than the cast of Ben Hur.

Haldex is only used on the freelander 2 - it is set to 50/50 4wd when pulling off then varies the percentage of 4wd from front to rear as required.

No other Land Rover has or curently uses it.

Cheers Doc. They don't list models on the Haldex website. Just the manufacturers that use them! Current, M135i in Estoril Blue with more extras than the cast of Ben Hur.
