Removal Procedure


    Object Number: 860042  Size: SH

    Caution: Ensure that the vehicle is properly supported and squarely positioned. To help avoid personal injury when a vehicle is on a hoist, provide additional support for the vehicle on the opposite end from which the components are being removed.

  1. Raise the vehicle on a hoist.
  2. Remove the right front road wheel.
  3. Remove the right upper wheelhouse panel

  4. Object Number: 861102  Size: SH
  5. Lower the vehicle enough to allow underhood access to the engine mount.
  6. Remove the 2 engine mount-to-midrail bracket fasteners.

  7. Object Number: 865474  Size: SH
  8. Place a floor jack under the engine oil pan. Use a block of wood between the oil pan and jack. Raise the powertrain just enough to unload the mount. The engine is raised enough when there is clearance between the mount and the midrail bracket.
  9. Notice: If the engine mount front cover stud turns or comes out during nut removal, the stud must be fully installed prior to installing the mount and/or nut. Damage to the front cover may occur if the stud is driven with the nut and does not sufficiently engage the front cover threads.

  10. Remove the 3 engine mount-to-front cover fasteners and remove the engine mount.

  11. Object Number: 861112  Size: SH
  12. From the engine side of the bracket, remove the four bracket-to-midrail fasteners.
