NOTE: For the purposes of this campaign, the above listed parts will be shipped in appropriate quantities and combinations with the related propeller shaft assembly. Gaskets and nuts will be in a separate box packed inside the main box containing the propeller shaft.

 

REPAIR PROCEDURE

This campaign involves replacement of the propeller shaft assembly.  During assembly of the front slip yoke component of the propeller shaft, the sealing cap may have become deformed resulting in the possibility of a transmission fluid leak.  Fluid leaking from the deformed sealing cap may leak onto the exhaust system.  Because none of the propeller shaft components are serviceable, the assembly must be replaced.  The following information outlines the procedure for replacing the propeller shaft assembly.

  • Before installation, inspect the new propeller shaft for:
    • Dents or cracks on the tube surfaces
    • U-joint bind or abnormal noise
    • Center support bearing for excess free-play, noise or binding
    • Oil seals for wear or damage
  • Record the customer’s radio station presets and (navigation system favorites where applicable).
  • Place the select lever in neutral.
  • Release the parking brake.
  • Disconnect the ground terminal from the battery sensor.
  • Raise the vehicle.
  • Remove the plastic engine under cover. CAUTION: The exhaust system may be HOT.
  • Remove the center exhaust pipe retaining nuts and spring bolts and separate the center exhaust pipe from the front exhaust pipe assembly.  Retain the nuts, springs, and bolts for later reuse.  Use brake parts cleaner to clean the bolt threads if contaminated with any leaked oil or fluid.
  • Disconnect the A/F and O2 Sensor wiring harness connectors.

  • Remove the bolt(s) which hold the center exhaust pipe assembly to the hanger bracket.
  • Remove the nuts holding the front exhaust pipe onto the cylinder heads. Retain these nuts for reuse.

front exhaust pipe

 

CAUTION:  The front exhaust pipe assembly is heavy and the heat shield edges can be very sharp.  Use appropriate personal protective equipment (PPE) and care while lifting.

  • Remove the front and center exhaust pipe from vehicle as an assembly.
  • Remove the exhaust pipe heat shield.

CAUTION: The edges of the heat shield can be very sharp.  Use appropriate PPE.

  • Apply a thin coat of spray type (NON-SILICONE) lubricant to the mating areas of cushion rubber(s) to ease pipe disengagement. Remove the bolts and self-locking nuts securing the muffler(s) to the rear exhaust pipe and remove the rear exhaust pipe.  Retain the bolts for reuse.  Use brake parts cleaner to clean the bolt threads of any residual oil or fluid before installation.

NOTE:  The self-locking nuts for the muffler installation and all the exhaust system’s gaskets are one-time use items.

CAUTION:  Where applicable, take precautions to keep the muffler(s) from contacting the underside of the rear bumper cover.

  • Apply a coating of CVT fluid to the machined surface of the new propeller shaft slip yoke.
  • Loosen but do not remove the 2 bolts securing the center support of the propeller shaft.
  • Remove the 4 nuts securing the propeller shaft to the differential input flange.
  • Remove the 2 center support bolts and remove the propeller shaft.
  • Install an extension plug into the back of the transmission or secure a plastic bag to the extension housing to catch any leaking CVT fluid once the old propeller shaft is removed.

extension plug

 

IMPORTANT NOTE:  There will be a very small amount of CVT fluid that will drip out of the transmission and the slip yoke after removing it from the transmissionAlways make sure to thoroughly clean any fluid residue off of the exhaust system and surrounding components.

  • Remove the plug or bag, insert the new propeller shaft into the extension housing and install the bolts securing the center support to the body. Torque the bolts to 52 Nm (38.4 ft. lbs.).
  • If there is a paint mark on the new propeller shaft, align it with the paint mark on the differential input flange as shown below. Use brake parts cleaner to make sure the 4 propeller shaft bolts and nuts are clean before reinstalling them.  Torque the nuts to 31 Nm (22.9 ft. lbs.).

  • Reinstall the heat shield and torque the 4 bolts to 18 Nm (13.3 ft. lbs.).
  • Reinstall the rear exhaust pipe assembly using new rear gasket(s) and self-locking nuts to secure the muffler(s). Torque the new self-locking nuts to 48 Nm (35.4 ft. lbs.).
  • Reinstall the front exhaust pipe assembly using new gaskets. Temporarily tighten the nuts holding the assembly to cylinder heads.
  • Reinstall the bolt(s) which hold the center exhaust pipe to the hanger bracket and torque to 35 Nm (25.8 ft. lbs.) for H4 models and 30 Nm (22.1 ft. lbs.) for H6 models.
  • Torque the nuts at the cylinder heads to 30 Nm (22.1 ft. lbs.). On H6 models, follow the sequence shown in the illustrations below.

nuts at the cylinder heads

 

  • Reconnect the A/F and O2 Sensor wiring harness connectors.
  • Re-connect the center exhaust pipe using a new gasket and torque the 2 spring bolt nuts to 18 Nm (13.3 ft. lbs.).
  • Lower the vehicle.
  • Reconnect the ground terminal to the battery sensor.

IMPORTANT:  Inspect the fluid level of the CVT following the procedure below:

  • Start the engine and raise the CVTF temperature to 35-45°C (95-113°F) using the SSM.
  • Operate the select lever from P → R → N → D and from D → N → R → P to fully circulate CVTF with the engine at idle.
  • Raise the vehicle again and with the engine at idle, remove the filler plug shown in the illustrations below.

CAUTION:  The exhaust system may be HOT.

  • The CVT fluid level is correct when it is up to bottom of the filler plug hole.

  • If necessary, adjust the fluid level.
  • Install a new filler plug gasket and torque to 50 Nm (36.9 ft. lbs.).

IMPORTANT:  ALWAYS check for any residual CVT fluid which may have dripped onto the exhaust or other components during reassembly or the fluid level inspection and thoroughly wipe it clean.

  • Reinstall the plastic engine under cover.
  • Lower the vehicle.
  • Reset the customer’s radio station presets and (navigation system favorites where applicable).
  • Road test the vehicle to verify smooth operation and no fluid leakage.
