VOLVO Gen 5 Haldex Pump for Rear Axle AOC AWD 31367750 - BorgWarner

Volvo Gen 5 Haldex Rear-Axle AWD Pump — OE 31367750 (BorgWarner)

The Haldex hydraulic pump builds and maintains the oil pressure that engages the rear-axle coupling on Volvo's AOC all-wheel-drive system, sending drive to the rear wheels when it's needed. This pump is a common wear item on higher-mileage cars or where service intervals have been missed, and its failure shows up as reduced rear-wheel traction and grip. Fitting a fresh pump restores full engagement of the AWD system.

This is a BorgWarner-boxed unit; BorgWarner is the OEM behind the Haldex system, so you're fitting the same design and manufacturing standard used on the original production line.

This listing is the BorgWarner-supplied unit. Also available as ET2329-ST (S-TEC).

Parts Included

Haldex hydraulic pump, complete with 2x fitting screws.
