Haldex and tire wear

[darry]

Hello Guys,

i have problem with my high tire wear on rear axle. I put new tires before 15tkm and front looks like new and rear are dead. Tires are equally wear. I have also bigger car consumption. I also have problems when the road is slippery or i rode over a canal or center line so rear axle seems to get slip or it feels like that rear axle is thrown sideways. I think that there is no any problem with haldex but i change oil and filter and no any change. It seems that there is some problem with rear differential that maybe is locked up under some condition or i do not know, because i tried to pull out the fuse for rear axle but without any change. I think that there is also some valve for the LSD but is strange that this problem is same even i pull out the fuse. No any DTC on dash.

Can anyone please help here?

When you jack up the car - is it possible to rotate one rear wheel?

[darry]

Yes it is. When i turn slowly i can see that both rear tyres turn together, when i turn faster other wheel turns really slowly.

[mortoss]

Jack up only one side and try tu turn. In my case you need to use some force but wheel turns

I know, that left wheel spin, but i did not test right. But this is really strange, because already two pairs winter and summer tyres were totally wear by really short amounth of time.

[mortoss]

Have you checked the alignment?

It was done before new winter and also summer tires in original opel service.

Wow, I have never seen such used tires (except in cars used during track days, drift etc.). Maybe you should try to go to some tune up shop to check your car on a dyno. Look for some shop with a dyno which can chekc 4x4 cars and then see how the power is distributed between each wheel?

Guys, is oil for haldex clutch and differential (eLSD) clutch same, or differential (eLSD) clutch use different oil? Do anyone from you have some pictures from inside of the haldex? How the eLSD clutch is depressed? I know that there is some valve which is controlled by haldex ECU and inside of the eLSD is some piston which push on clutch pack, but how is this piston depressed?

[Robert36pl]

No, you have 2 different oils.
Change:
oil for clutch - 93165388 - about 0,7l
oil for haldex- 93165387 - 350-400ml
seal or gasket/filtr - 20986573

You have a problem with e LSD. At the beginning I also wanted to advise you to jack up one rear wheel and check if it turns. But if the car is off e LSD does not work and the differential is open
Are you the owner of the news? Because there is the possibility that someone modified the eLSD electronics so that the differential was still closed or haldex is modified and still switched on.
Is there only one fuse that you left behind for the operation of eLSD and haldex?
To be sure, you can disconnect the plug at the oil pump on the rear axle.
Does your car respond well to steering wheel? Is the turning circle increased? Can you do it with another insignia?
Have any components of the drive system been repaired in your car?
Lift one rear wheel and check if it turns. If it does not rotate. There maybe a problem with haldex or e LSD. Maybe some valve blocks pressure. Maybe a problem is with the pressure accumulator. And the pressure is in the system even when the car is turned off. Of course, when car is on pressure will also be.
If the wheel rotates, You can be sure that the pressure does not block Haldex and e LSD.
If one raised wheel can not be rotated. Pick up the second one. The two rear wheels are to be raised. Rotate one of them. If the haldex is turned on the second one will turn in the opposite direction. If the haldex is turned off and the LSD is closed, both wheels will rotate in the same direction.
These are the tests you can do with the car turned off so that you can be sure that haldex and e LSD are off.

@Robert36pl You have incorrectly written the oil 93165388 to the differential (dyfra) and not the clutch. Haldex ok.
@darry Before you start doing what I wrote you with this lifting the wheels. Disconnect the cable from the pump or valve that can be seen in the foreground picture. This is an e LSD valve. Ride the car and see if there is a change.

This valve is above the half-axis of the left rear wheel. Two hydraulic and electric hoses are connected to it.

Hello guys,

thanks a lot for replies.

i think that i will have locked rear diff, because when i had both rear tires jacked up so when i turned with left wheel so second one turned in same direction even my car was or was not started.

guys i need to confirm this:
1. if the haldex is off both rear tires need to turn in same direction?
2. when is on, one tyre turn to left and second to rigt?
3. i know that there are two oils but which oil is used for clutch in differential?
4. differential clutch is in default locked?
5. the fuse in car is for rear haldex computer but car had same problem even i disconnect this fuse

today i checked rear tyres and they are really rought

[hubertus]

1 Yes. Then the differential mechanism does not work. The shaft on which there is less resistance moves. If less resistance is on the disconnected haldex clutch, both wheels will spin together. That's why you can pick up one wheel on the switched off car to force the differential to work. Then, by turning the wheel, you will move the shaft in the haldex coupling
2 Yes if the haldex is switched on then through the shaft and gearboxes, the resistance is acting and by means of the satellites the other wheel is rotated in the opposite direction.
3 Haldex oil and eLSD oil are the same. The oil in the differential gear is different.
4 I do not think I do not know.
5 Is there only one fuse? Try to disconnect the pump and valve with I showed you in the picture. The one with two hydraulic hoses and one electric wire.

[darry]

Guys i think that we make a little mess here in information. When the car is turned off and back both tyres are lifter so one tyres need to turn to left and other one to right, because eLSD and haldex is switched off. Only when the eLSD is on, both tyres need to turn in same direction.

[hubertus]

That should be theoretically. Please, do it and write what happened.
Theoretically, because as I wrote earlier, the differential rotates where there is less resistance.
If you raise the rear axle. And you will turn one wheel, Your movement must be transferred somewhere.
1 Can be transferred to the second wheel. If there is more resistance on the haldex than on the second wheel. And then it will turn the other way around.
2 Can be transferred to the shaft of the disabled haldex. If the resistance on the differential is greater than on the disabled haldex. And then the wheels will spin together.
Maybe I am writing too intricately.
Try to raise both rear wheels and spin. See what happens. If you do it the other way around, You can be sure that the differential opens at least when the car is switched off.
If the wheels will spin together. Leave one of them to give him more resistance. And force the differential to work. Then, as I wrote above, yours movement will be transferred to the shaft of the excluded haldex.
If the wheel can be turned, the differential eLSD is open. If the wheel can not be turned, the differential e LSD is closed. You will know if the differential is running or blocked. When the car is turned off

Hello guys,

i tried to spin when on rear wheel was on the ground and vice versa and botw were able to spin to both directions, but it seems that there is some resistance.

here is video when both wheels are lifted and how they spin:


i asked my friend which have same insignia so i will post here also result from his car as i will have them.

[hubertus]

The video shows that when your car is turned off your differential is working good..
You can see what I wrote about. The movement is transmitted where there is less resistance. Usually it is the shaft of the excluded haldexa. That's why the other wheel is spinning in the same direction. But you can see that not always and not with the same speed as the wheel moved by you. So the differential on the turned off car is open. The question is whether the same is true when the engine is running and the haldex pump works?
What is this noise 0:11?
To make sure and how I wrote to force the differential to work. Repeat this test with the other wheel on the road. Then you will have 100% confidence.

[darry]

As i wrote, when i have other wheel on the ground it was possible to turn them to both directions or maybe i did not catch the point?

i also tried to test this when car was turned on in park and N mode and i think that both tires were able to work together and when i spin with one wheel faster there was automatically connected the second wheel (to same speed), so it mean that eLSD is working probably.

today i will try to test this on my friend car, so i will have direct comparsion about rear diff.

i will test:
1. if both rear tires will be up so what will happened when i will rotate with one wheel, what will do other one
2. take up only one wheel and tried to turn and wice versa.

is it ok guys?

[hubertus]

Do the same as with your car on video. If it's the same, it's okay with you.

[darry]

Yesterday i took my car to the best proffesional in czech for OPEL and we tried over diagnostic to check valves in haldex and in diff and everything works ok. He also tried to turn with wheels and when he catch front right wheel the rear tyres were able to turn in different direction. We also made a test drive when we take car to the limit and he think that when we take left curve so car is run ok but when we take right turn so he feel that car is understeer. But as he mentioned we are unable to check this rear haldex and diff more, because we only can open or close valves, but we cannot step them.
