Overview
| MLIT filing number | 1118690 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | April 18, 2007 |
| Manufacturer(s) | Mazda, Suzuki |
| Component | Propeller shaft |
| Production period | March 2001 — March 13, 2007 |
| Vehicles affected | 381,551 units |
Defect
In four-wheel-drive freight vehicles, the rear propeller shaft bearing is made of an unsuitable material. During extended high-speed operation, lubricating oil temperature rises, accelerating a chemical reaction between the sulfur in the oil and the copper in the bearing, which generates large quantities of copper sulfide. The copper sulfide accumulates on the bearing, increasing sliding resistance and raising temperatures further. This causes the bearing to pull out of the transfer case, producing abnormal noise. In the worst case, the transfer case and output shaft sustain damage, the rear propeller shaft detaches, and the vehicle becomes inoperable.
Corrective action
On all vehicles, inspect the rear propeller shaft. Where no heat discoloration is found, replace the lubricating oil with the corrected part. Where heat discoloration is found, replace the transfer case with the corrected part and replace the rear propeller shaft with a new unit.

状況
四輪駆動の貨物自動車において、リヤプロペラシャフト軸受の材質が不適切なため、長時間の高速走行を行った場合、潤滑油が高温になり、潤滑油中の硫黄成分と当該軸受の銅の化学反応が促進され、硫化銅が多量に生成されることがある。そのため、そのまま使用を続けると、当該軸受に硫化銅が堆積して、摺動抵抗が増大することにより更に高温となり、軸受がトランスファケースから抜けて異音が発生し、最悪の場合、トランスファケース及びアウトプットシャフトが破損してリヤプロペラシャフトが脱落し、走行不能となるおそれがある。
改善措置
全車両、リヤプロペラシャフトを点検し、熱変色が認められないものは、潤滑油を対策品に交換し、熱変色が認められるものは、トランスファケースを対策品に交換するとともにリヤプロペラシャフトを新品に交換する。
