Thumbs up Rear noise diff or haldex ? Where to repair ?

Good evening everyone,

Now after repairing my AWD mechanical faillure. The AWD is working ! However, I have a noise coming from the rear now. I don't know if it is the haldex unit or the diff itself. The diff seems commun with freelander 2 who suffer from diff faillure as a commun issue.

Anyone know some good company that can repair diff or haldex unit ?

I still need to investigate but so far I can hear a noise if I move the input flange.

Anyone else experienced this kind of issue ?

I have a video of the noise when I move the flange if this can help someone.

Thanks all

My thought process ... 1st I'd check the quality / colour of the diff oil. After 85k mine looked almost new. I've not come across my diff issues here. The colour might give a clue to the diff state. There's more metal bits (bearings n gears) which are more prone to noise than the hydraulics in the haldex which is just a series of clutch plates which at the right time join the front back prop to the rear diff. As u are under there check the state of the haldex oil. Mine was horible and I flushed oil through 5+ times before I started to look reasonable when removed. One thing I learned is volvo wanted 10 hrs to remove the diff ( 2004 v70 AWD R) my issue was haldex dem not rear diff.
Sorry don't know any 3rd party repairers.
Good luck..
Cheers Bob.
