Output Shaft Seal: Removal

All vehicles 

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING article.

   All vehicles except Gasoline Turbocharged Direct Injection (GTDI) 

2. Remove the 2 exhaust Y-pipe-to-muffler and tail pipe flange nuts.
   • Discard the nuts and gasket.
NOTE: The resonator must be supported to prevent damage to the flexible pipe.
3. Using a length of mechanic's wire, support the resonator.

   GTDI vehicles 

4. Remove the 4 LH and RH exhaust flexible pipes-to-underbody catalytic converter nuts.
   • Discard the nuts and gasket.

   All vehicles 

NOTE: Index-mark both the driveshaft flanges for installation.
5. Remove the 4 driveshaft-to-Power Transfer Unit (PTU) output flange bolts. Disconnect the driveshaft from the PTU and position it aside.
   • Using mechanic's wire, support the driveshaft.
NOTE: Rotational torque of the PTU rear output shaft flange must be measured and recorded using a Nm (lb-in) torque wrench for correct pinion bearing preload when reassembled. This will be the torque-to-turn measurement.
