REMOVE ENGINE ASSEMBLY
1. Remove the engine assembly Click here.
INSTALL ENGINE ON TO ENGINE STAND
1. Install the engine onto an engine stand with the bolts.
  Note
  - Pay attention to the angle of the sling device as the engine assembly or engine hangers may be damaged or deformed if the angle is incorrect.
  - With the exception of installing the engine assembly to an engine stand or removing the engine assembly from an engine stand, do not perform any work on the engine while it is suspended, as doing so is dangerous.
2. Remove the 2 bolts and 2 engine hangers.
REMOVE FRONT DIFFERENTIAL CARRIER ASSEMBLY
1. Support the front differential carrier assembly with a jack.
  
  CAUTION:
  
  As the front differential carrier assembly is very heavy, securely support it with the jack.
2. Remove the 4 bolts and front differential carrier assembly.
  Note
  
  Do not damage the installation surface when removing the front differential carrier assembly.
  
  The remaining oil may leak out when removing the front differential carrier assembly.
REPLACE FRONT DIFFERENTIAL CASE OIL SEAL
1. Set the front differential carrier assembly to an overhaul stand as shown in the illustration.
2. for LH:
  1. Using SST, remove the front differential case oil seal LH.
    
    SST
    
    09308-00010
  2. Using SST and a hammer, tap in a new front differential case oil seal LH to the front differential carrier assembly.
    
    SST
    
    09608-32010
    
    09950-70010 ( 09951-07100 )
    
    Standard depth
    
    -0.5 to 0.5 mm (-0.0197 to 0.0196 in.)
    
    Note
    
    Tap the front differential case oil seal LH uniformly so that the oil seal is straight.
    
    Do not excessively tap the oil seal.
    
    Make sure the difference between the maximum and minimum measured values is less than 0.57 mm (0.0224 in.), as a greater difference may lead to oil leaks.
3. for RH:
  1. Using SST, remove the front differential case oil seal RH.
    
    SST

    *1 Front Differential Case Oil Seal RH
    
    Using SST and a hammer, tap in a new front differential case oil seal RH to the front differential carrier assembly.
    
    SST
    
    09550-60010 ( 09951-00570 )
    
    09950-70010 ( 09951-07100 )
    
    Standard depth
    
    1.0 to 2.0 mm (0.0394 to 0.0787 in.)
    
    Note
    
    Tap the front differential case oil seal RH uniformly so that the front differential case oil seal RH is straight.
    
    Do not excessively tap the oil seal.
    
    Make sure the difference between the maximum and minimum measured values is less than 0.47 mm (0.0185 in.), as a greater difference may lead to oil leaks.
4. Remove the front differential carrier assembly from the overhaul stand.

Standard depth
-0.5 to 0.5 mm (-0.0197 to 0.0196 in.)
