Part 2




Camshaft














Removal

NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan may cause engine failure.

All camshafts

41. NOTICE: Do not allow the intermediate shaft to rotate while it is disconnected from the gear or damage to the clockspring may occur. If there is evidence that the intermediate shaft has rotated, the clockspring must be removed and recentered. For additional information, refer to Restraints and Safety Systems &/or Air Bag Systems.

NOTE: Index-mark the steering column shaft position to the steering gear for reference during installation.

Remove the bolt and disconnect the steering column shaft from the steering gear.
- Discard the bolt.






42. Remove the 4 Y-pipe-to-catalytic converter nuts.
- Discard the nuts.






43. Remove the 2 Y-pipe flange nuts.
- Detach the exhaust hanger and remove the Y-pipe.

- Discard the gaskets and nuts.






All-Wheel Drive (AWD) vehicles

44. NOTE: Index-mark the driveshaft for installation.
Remove and discard the 4 bolts and support the driveshaft with a length of mechanic's wire.






All camshafts

45. Remove the drain plug and drain the engine oil.
- Install the drain plug and tighten to 27 Nm (20 lb-ft).






46. Remove and discard the engine oil filter.





47. Remove the Power Steering Pressure (PSP) tube bracket-to-steering gear bolt.





48. Remove the bolt, rotate the clamp plate clockwise and disconnect the PSP (Power Steering Pressure) tube from the steering gear.
- Discard the O-ring seal.






49. Remove the engine roll restrictor-to-subframe through bolt and loosen the engine roll restrictor-to-transaxle bracket through bolt.





50. NOTE: RH shown, LH similar.
Remove and discard the upper stabilizer link nuts.






51. NOTE: The hex-holding feature can be used to prevent turning of the stud while removing the nuts.

NOTE: RH shown, LH similar.

Remove and discard the tie-rod end nuts.
- Separate the tie-rod ends from the wheel knuckles.






52. NOTICE: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part number or equivalent part, if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

NOTICE: Use care when releasing the lower arm and knuckle into the resting position or damage to the ball joint seal or Constant Velocity (CV) boot may occur.

NOTE: Use the hex-holding feature to prevent the stud from turning while removing the nut.

NOTE: RH shown, LH similar.

Remove and discard the lower ball joint-to-wheel knuckle nuts.
- Separate the lower ball joints from the wheel knuckles.






53. Using a wax pencil, mark the relationship of the front subframe to the underbody at the mounting locations.

54. Position the Powertrain Lift under the subframe assembly.





55. NOTE: RH shown, LH similar.
Remove the subframe bracket-to-body bolts.






56. NOTE: RH shown, LH similar.
Remove the rear subframe bolts and the subframe brackets.






57. NOTE: RH shown, LH similar.
Remove the front subframe bolts.






58. Lower the subframe assembly from the vehicle.

59. Pull the RH wheel knuckle outward and rotate it toward the rear of the vehicle.
- Secure the RH wheel knuckle assembly.






60. Remove the 2 intermediate shaft bracket nuts.





61. Remove the intermediate and halfshaft assembly.

62. NOTICE: The sharp edges on the stub shaft splines can slice or puncture the oil seal. Use care when removing the stub shaft from the transmission or damage to the component may occur.

Using the Slide Hammer and Halfshaft Remover, remove the halfshaft from the transmission.






63. Remove and discard the circlip from the stub shaft.





64. Remove the 2 RH halfshaft support bracket studs.





65. Remove the 4 bolts and the RH halfshaft support bracket.





66. Remove the 2 secondary latches from the transmission fluid cooler tubes at the transmission fluid cooler thermal bypass valve.





67. Using the Transmission Cooler Tube Disconnect Tool, disconnect the transmission fluid cooler tubes from the transmission fluid cooler thermal bypass valve.





68. NOTE: Position a block of wood under the transaxle.
Install the Powertrain Lift and Adjustable Grip Arms.






69. Remove the transaxle mount through bolt and nut.





70. Remove the bolt, 3 nuts and the transaxle mount bracket.





71. Remove the nut, bolt and engine mount brace.





72. Remove the 4 engine mount nuts.





73. Remove the 3 bolts and the engine mount.





74. Lower the engine and transaxle assembly from the vehicle.

75. Disconnect the PCV hose from the PCV valve.





76. Disconnect the Throttle Body (TB) electrical connector.





77. Detach the wiring harness retainers from the upper intake manifold.





78. Remove the upper intake manifold support bracket bolt.





79. Remove the wire harness pin-type retainer and the fuel tube bracket bolt from the upper intake manifold.





80. NOTICE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

Remove the 6 bolts and the upper intake manifold.
- Discard the gaskets.
