Haldex Coupling Pump Repair Kit – Generations 1 / 2 / 3 | Seal Kit
The Haldex AWD coupling relies on the internal oil pump to generate the hydraulic pressure that engages the rear axle. When the pump seals wear, oil pressure drops — causing delayed or absent rear wheel engagement and AWD faults. This seal kit rebuilds the pump, restoring correct AWD operation.
