REAR DIFFERENTIAL DISASSEMBLY

id031400800500

Warning

• The engine stand is equipped with a self-lock mechanism, however, if the rear differential is in a 

tilted condition, the self-lock mechanism could become inoperative. If the rear differential 
unexpectedly rotates it could cause injury, therefore do not maintain the rear differential in a tilted 
condition. When turning the rear differential, grasp the rotation handle firmly.

1. Disassemble in the order indicated in the table.
