after changing all of the differential bearings I had to face problems of the rear axle and maneuver in tight bends.
it jerks.
I consult the forum and I read that operation could "broke" Haldex.
my situation
no errors on display
no errors by plug-in computer under the steering
increase of consumption
claking from the rear axle in the outer wheel on sharp bend


Some feedbacks after I have been to the mechanic.

 to deactivate the Aldex simply remove the fuse FB6 near the spare wheel in the back.
This cuts off power to the unit.
at this point the effect that we can have is twofold.

it would be appropriate to put the car on a hydraulic bridge with freewheels.

 if you insert the first gear and turns the rear wheel by hand, it should turn.
if it does not run then it means that the hydraulic system of ahldex is REMAINED CLOSED and continues to transmit traction.
but if the rear wheel spins then it means that the Haldex is unlocked (and it could be a different issue).

between the two results the lock is to be preferred because haldex is not powered, so it is very likely that the problem is mechanical (and there is little mechanical inside the hAldex).

we proceeded by removing completely the Haldex and washing it with a special liquid, thoroughly cleaning the pump and replacing the filter.
checking plug the pump, and all the wiring there is no sign of overvoltage.

I'm waiting for oil for Haldex and then finally I will be able to tell if the solution is less expensive than I imagined.
doing the rear diff bearings, probably all the dirty in the haldex moves and block the whole device.
to complete thi aspect LR, in italy does't provide kit for haldex so, if you have a haldex4 you ca buy the haldex filter from volvo part nr. 31325173 for 35 euros.


let's keep our fingers crossed

Work is done.
Refilling with the right procedure fuond in this helpful forum, filter changed.
Haldex Is unlocked and rear wheels over the bridge with first gear on, are free.
Trying the car in the mud four wheel drive works and the other programs of terrain response too.

Everything seems working correctly but in te bord computer the instant consumption seems to be too high.
In the thigh bends no more problems.

Some doubt on the high diesel consumption.
