I’ve used Haldex coupling pump repair kits from Klifex USA https://klifex.net/collections/haldex-coupling-pump-repair-kits, and they worked great for restoring proper AWD performance. Their kits come with quality components, and the installation is pretty straightforward if you follow the steps carefully. The biggest tips are to keep the pump area clean, replace the filter, and make sure the fluid is fresh. Klifex USA has been reliable in terms of shipping and support, so definitely worth checking out.
