2 1 DIFFERENTIAL SYSTEM DRIVE LINE / AXLE DIFFERENTIAL DIFFERENTIAL SYSTEM PRECAUTIONS 1. Before disassembly, clean the outside of the differential assembly and remove any sand or mud to prevent it from entering the inside of the assembly during disassembly or installation. 2. When disassembling a connecting part made of light alloy such as a differential carrier cover, lightly tap it in with a plastic hammer. Do not attempt to pry it off with a screw driver. 3. Always organize and arrange the disassembled parts properly to protect them from dust or other foreign matter. 4. Fully wash and dry each part before installing it, and apply differential gear oil.do not use alkaline cleaner for aluminum or rubber parts or ring gear set bolts.in addition, do not clean rubber parts such as O-rings or oil seals with cleaning oils (such as solvent). 5. Sufficiently coat the sliding and rotating surfaces with differential gear oil before installation. 6. When securing parts in a vise, do not place the parts directly in the vice. Be sure to place aluminum plates between the parts and the vice. 7. Be extremely careful not to damage the contact surfaces of the case. Such damage may cause oil leaks. 8. Before applying sealant, remove the old adhesive or old sealant from the seal, and clean the area with a solvent. 9. Do not fill oil immediately after installing sealed parts. Wait at least an hour. 10. As it may cause oil leaks, do not scratch or damage the contact surfaces of the oil seal, O-ring, or gasket. 11. When tapping the oil seal into the end of the differential carrier, inspect the installation depth at 3 or more locations on the oil seal circumference. To prevent oil leakage, make sure that the difference between the maximum and minimum measurement values is within the standard value range. 12. When press-fitting an oil seal, be extremely careful not to damage the oil seal lip or its outer circumference. 13. When replacing a bearing, replace the outer and inner races as a set. OPERATION CHECK 1. INSPECT DIFFERENTIAL OIL CHECK OIL LEVEL (See page -3 for the procedure.) CHECK FOR OIL LEAKS (1) Visually inspect whether oil is leaking from the oil seal, differential carrier, plug, case fitting surface, or any other parts.

4 3 DIFFERENTIAL OIL DRIVE LINE / AXLE DIFFERENTIAL DIFFERENTIAL OIL ADJUSTMENT 1. DRAIN DIFFERENTIAL OIL Put an oil tray under the drain plug. Remove the drain plug, then remove the filler plug. (c) Check that the oil has drained completely. (d) Tighten the drain plug using the specified torque. Torque: 61 N*m (625 kgf*cm) 2. ADD DIFFERENTIAL OIL Make sure that the vehicle is level. Remove the differential filler plug and gasket. (c) Insert the gear oil injection nozzle, and slowly fill with hypoid gear oil (differential oil). If the oil is filled too quickly, it may flow back. This may cause you think mistakenly that the specified amount has been added. (d) Leave to stand for 5 minutes after the oil overflow from the filler plug stops. 0-5 mm Oil Level Filler Plug Wire C INSPECT AND ADJUST DIFFERENTIAL OIL Using your fingers or a wire, inspect the oil level. Within 0 to 5 mm from the bottom edge of the filler plug hole As it may take some time for the oil to fill into the differential, be sure to wait before checking the oil level. If the oil level is too high or too low, it may cause trouble. Stop the vehicle on a level road. If the oil level is low, check for oil leaks and add oil. (c) After oil is added, re-check that the oil has been filled up to the specified level. (d) Install the differential filler plug and a new gasket. T = 49 N*m (500 kgf*cm) (front differential) T = 61 N*m (625 kgf*cm) (rear differential) 4. ADD DIFFERENTIAL OIL Remove the differential filler plug and gasket. Rear differential (with LSD) (1) Add differential hypoid gear oil (LSD) Within 0-5 mm from the bottom edge of the filler plug opening. Full capacity: Approx liter (c) Front and rear deferential (1) Add hypoid gear oil (differential oil) Within 0-5 mm from the bottom edge of the filler plug opening.

5 DIFFERENTIAL DIFFERENTIAL OIL 4 (d) (e) Full capacity: Approx liter Approx liter (rear differential) Check the oil level. Install the differential filler plug and a new gasket. T = 49 N*m (500 kgf*cm) (front differential) T = 61 N*m (625 kgf*cm) (rear differential) After adding oil, re-check the oil level after driving.
