Volvo Gen 3 Haldex tear-down.

Tearing into my used 140k Haldex unit to diagnose a noise issue.

Thanks for this video, I don’t think there’s anything like it on the internet.

This is THE EXACT video I've been searching for. Thank you for posting, Rob.

Welcome. What's wrong with your unit?

[@helidevil123]

@@mnopracing I have a unit with burnt clutch packs from the "real AWD" experiment, swapping DEMs ad pressure sensors, and I'm tired of my AWD reliably failing every winter for one reason or another. I'm thinking to pull out the old burnt clutch pack and drill holes to pin the stupid thing and make the system mechanical again, like it should have been from conception.

@@helidevil123 So you would be effectively welding the haldex solid, right. Kind of a full time awd setup?

[@helidevil123]

@@mnopracing Exactly. Then we'd see where the next weak link is. :D

@@helidevil123 You might run into issues with binding between the front and rear wheels. There is a guy who converted an 850r to awd and welded up the Vc so that the rear wheels were no longer able to freewheel. Basically doing what your planning on, just with the gen 1 awd system. He had issues at low speed turning with the rear wheels wanting to "hop". I'm assuming you've tried getting the haldex to just be locked all the time threw a haldex controller, right?

Thanks a lot your video save me a lot money ...the quality video and light make a difference......I'm speechless and happy thanks

[@mnopracing]

No worries. I was exited just to take it apart and see why it failed.

[@paulo5861]

Could the noise be coming from the pinion shaft bearings that the AOC unit connects to?

I have a 2009 s80 with 275k on it and when I accelerate it shutters ever so slightly. Volvo told me it is a failing haldex. The fluid was changed at 160k I drive mostly highway. Do you know the part number for the clutch packs

[@Noidea242]

Did your Volvo shutter under acceleration?

[@roscaionutmarius3670]

Does any body knows from where to buy The Rollers inside the Clutch? Shown in video at minute 14:00

[@Noidea242]

Any part numbers you could give me would be helpful
