SERVICE INFORMATION:
Beginning at the start of production for 2001 on all AX4S transaxles, Ford Motor Company
introduced a new design pump bearing that includes an integrated seal, as shown in Figure 47.
When this new design bearing and seal assembly went into production, it was installed with the
seal on the valve body side of the pump instead of the rotor side.
Greatly reduced pump bearing, pump rotor and vane ring failure, for much improved durability
and reliability.
