Overview
| MLIT filing number | 1114680 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | June 29, 2005 |
| Manufacturer(s) | Mitsubishi |
| Component | Axle |
| Production period | September 17, 1993 — July 30, 2004 |
| Vehicles affected | 5,442 units |
Defect
The front axle knuckle stopper area has insufficient strength. When excessive stress is generated at the kingpin boss during vehicle turns or similar maneuvers, cracks may develop at the stopper. Increased kingpin play accelerates crack progression. Continued use allows the cracks to advance until the boss fractures. In the worst case, the kingpin separates from the boss, causing the tire to lean and rendering the vehicle inoperable.
Corrective action
Inspect the front axle on all vehicles and replace with a corrected part on any vehicle not already equipped with one. Additionally, establish a new wear limit for the front axle kingpin bore and add it to the service standards. Because full supply of corrected parts will take time, as an interim measure inspect the kingpin bore on all vehicles: replace immediately with a corrected part if cracks are found, or schedule replacement at a later date if no defects are present.

状況
フロントアクスルのナックルストッパ部付近の強度が不足しているため、車両旋回時等にキングピンボス部に過大な応力が発生した場合、当該ストッパ部に亀裂が発生するものがある。また、キングピンのガタが大きくなると、この亀裂が促進される可能性がある。そのため、そのまま使用を続けると、亀裂が進行してボス部が破断し、最悪の場合、ボスからキングピンが外れ、タイヤが傾き走行不能となるおそれがある。
改善措置
全車両フロントアクスルを確認し、対策品未装着の車両については、対策品と交換する。また、フロントアクスルのキングピン穴部の摩耗限度を新たに設定し整備基準に追記する。 なお、対策品の全数供給に時間を要するため、当面の暫定措置として、当該キングピン穴部を点検し、亀裂のある場合は対策品と交換し、問題の無い場合は、後日、対策品と交換する。
