Exactly why I made the video! I seek to educate and help others. 😃

Excellent video and step by step guide. My question, where did you buy that copper ring, brushes and o-rings for the pump? Thanks.

[@SolvingSaab]

@@alfonsoaslbox4121 directly from haldex site or on ebay! Just do a few searches for aoc brush kits on google.

Excellent video 👍 What fault code did you have?

[@SolvingSaab]

C0407-64 low oil pressure. I knew it wasn’t the clutch seal because I did that fix already and fluids were not cross contaminated.

@@SolvingSaab I have owned my TX for 13yrs and got my first XWD fault code last week. Not had a chance to investigate the code is C040704 WIS says AWD Oil Pump Motor Open. The differential clutch pump current is less than 0.3 A for 30 s. I will need to investigate.

@@firesaab31 that may be a bad pump, try a xwd service and that may fix it.

@@SolvingSaab I have serviced my Haldex every 2yrs since owning the car despite covering just 3000 miles a year. I serviced just a few weeks ago. I should have time to investigate next week. Keep up with good work and keep posting videos 👍

What were some of the indications that the pump was bad before it was dissembled?

[@SolvingSaab]

@@okletsskate a code on the tech 2 for low pump pressure. Usually this is a bad filter or bad pump.

@@SolvingSaab Cool, thank you. I know what to look our for!

I just have a question for you! If I have in stock a Differential Pump not ELSD can I put it on my car that have ELSD ? thx

[@SolvingSaab]

@@Marc-AndreRiendeau-jf4nr LSD and ELSD pumps are not interchangeable because they have different plugs. The kit in the video will fix both though because they are the same internally.
