Removal Procedure

    Notice: To prevent oil leaks and seal damage, the engine's oil pan must be removed if the rear oil seal carrier requires replacement.

  1. Remove engine oil pan. Refer to "Oil Pan - In Chassis" removal procedure in the General Information section of this service manual.
  2. Remove rear oil seal assembly bolts and discard bolts. New bolts are supplied with seal kit and will be used for installation.
