For the power trains of 4WD vehicles, the gear ratio of the front differential is not properly set, and therefore, while driving in 4WD mode, twisted torque may occur on the power train in proportion to the difference between the numbers of front and rear tyre revolutions depending on the wear of the rear tyres and the load conditions. With such torque, even as the mode is manually switched from 4WD to 2WD, the driving may remain unchanged. When driving at high speed in such a condition, the front differential may generate heat damaging the oil seal, which could allow oil to leak, in which case the bearing and the gear could burn out and at worst the front wheels could lock causing the vehicle to stall.
Case Number:
RJ-1295-2
Make/model:
Issued:
Thu, 2004-11-11
Component:
front differential
Affected:
10 429
Correction:
The front differential should be replaced with the factory approved replacement unit, and the 4WD control unit should be replaced with the one that includes additional functions; the unchanged 4WD mode warning and the oil temperature warning. Incidentally, it will take time to supply all the factory approved replacement units, and therefore as a temporary measure, the 4WD operation and the oil amount in the front differential should be checked, and if any abnormality is found, the following actions should be taken; (1) The front differential should be replaced with a new one. (2) The vehicle owner should be informed not to use the 4WD mode until the permanent factory approved replacement is carried out. (3) The caution sticker to inform the instructions in case of using the 4WD mode in an emergency escape etc. should be placed on the sun visor, and the vehicle owner should be informed of it.
Identification:
sticker on the back of the fuse box cover located inside the passengers compartment, orange one for the temporary measure, red one for the permanent factory approved replacement
