Ferrari FF & GTC4Lusso 4RM PTU Rebuild – 305902 / 324841

Ferrari FF & GTC4Lusso 4RM PTU Rebuild

GTE Engineering rebuilds the front Power Transfer Unit (PTU) used in applicable Ferrari FF and GTC4Lusso 4RM vehicles. The front PTU is a separate assembly from the rear transmission. Provide unit identification and diagnostic findings before selecting a service.

PTU Identification

Choose the correct service stage

The selected stage defines the work included. An inspection or targeted repair is not the same scope as a full PTU rebuild.

• Stage 1: right-side end-shaft bearing replacement and full inspection.
• Stage 2: PTU rebuild addressing the most common internal leak concern.
• Stage 3: PTU rebuild with the Power Bearing Upgrade.
• Stage 4: full rebuild including SX and DX clutch sets and the work specified in Stages 3 and 1.

Inspection, rebuilding and testing

Depending on the selected stage and inspection findings, work involves disassembly, seal and gasket replacement, bearing and internal-component assessment, hydraulic pump inspection, resealing and reassembly. Final bench checks cover pressure, engagement function and leaks. Additional damage and work outside the selected stage must be identified in the estimate before proceeding.

Fluids: gear and hydraulic oils are sold separately. Confirm filling, delivery condition and installation requirements for your job before dispatch or fitting.

Plan the complete repair

Discuss any bearing, cooling or calibration upgrade request with GTE before ordering; availability and scope must be confirmed for the specific PTU. Vehicle diagnosis, removal, installation and commissioning must be coordinated separately with GTE or the installing workshop. A component rebuild does not establish the condition of every vehicle-side system.

Contact GTE with symptoms, fault codes and unit photographs to agree the service stage, additional work and receiving arrangements.
