PRECAUTION [04/2013 - ]
- 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 and installation.
- When removing an installed part made of light alloy such as the differential carrier cover, tap it off with a plastic hammer. Do not attempt to pry it off with a screwdriver.
- Always arrange disassembled parts in order and protect them from dust.
- Before installation, thoroughly clean and dry each part and then apply hypoid gear oil API GL-5 or differential gear oil LT 75W-85 GL-5 to them. Do not use alkaline cleaner for aluminum or rubber parts and ring gear set bolts. Also, do not clean rubber parts such as oil seals with non-residue solvent.
- Coat sliding surfaces and rotating parts with hypoid gear oil API GL-5 or differential gear oil LT 75W-85 GL-5.
- When holding a part in a vise, be sure to place aluminum plates between the part and vise. Do not put it directly in the vise.
- Do not damage the sealing surfaces of the case. Such damage may cause oil leakage.
- Do not add oil within 1 hour or allow rapid acceleration or deceleration within 12 hours of installing sealed parts.
- Damage to surfaces in contact with an oil seal or gasket may cause oil leakage.
- When press-fitting an oil seal, do not damage the oil seal lip or outside periphery.
- When replacing a bearing, replace the inner and outer races as a set.
- When replacing a hypoid gear, replace the ring gear and drive pinion as a set.
