1. REAR DIFFERENTIAL
When replacing a rear differential assembly, select the correct one according to the following table.
NOTE:
•Using a different rear differential assembly will cause the drive train and tires to drag or emit abnormal
noise.
•For option code, refer to “ID” section.
2. IDENTIFICATION
Identification label positions are shown in the fol-
lowing figures. For details concerning identification,
refer to the “ID” section.
3. REAR DIFFERENTIAL GEAR OIL
Recommended gear oil:
GL–5 (75W–90)
NOTE:
Each oil manufacturer has its base oil and addi-
tives. Thus, do not mix two or more brands.

C: CAUTION
•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Remove contamination including dirt and corrosion before removal, installation or disassembly.
•Keep the disassembled parts in order and protect them from dust and dirt.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
•Be careful not to burn yourself, because each part on the vehicle is hot after running.
•Use SUBARU genuine grease etc. or equivalent. Do not mix gear oil, grease, etc. with those of different
grades or from other manufacturers.
•Be sure to tighten fasteners including bolts and nuts to the specified torque.
•Place shop jacks or rigid racks at the specified points.
•Apply gear oil onto sliding or revolution surfaces before installation.
•Before installing the O-ring or snap ring, apply a sufficient amount of gear oil to avoid damage and defor-
mation.
•Before securing a part on a vise, place cushioning material such as wood blocks, aluminum plate, or cloth
between the part and the vise.
•Avoid damaging the mating surface of the case.
