Overview
| MLIT filing number | 1115130 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | September 14, 2005 |
| Manufacturer(s) | Mitsubishi |
| Component | Steering linkage |
| Production period | December 1982 — August 30, 1990 |
| Vehicles affected | 7,843 units |
Defect
Defective welds are present at the ball joint socket weld of the bell crank, allowing repeated steering operations such as stationary turns to initiate a crack at the weld. As the crack progresses, in the worst case the affected area may fracture, causing the ball joint socket to pull free and resulting in loss of steering control.
Corrective action
On all vehicles, the bell crank is replaced with a corrected part. Because full supply of corrected parts requires time, an interim measure is implemented: the ball joint socket area is inspected, and any unit found to have a crack is immediately replaced with a corrected part, while units showing no defects are scheduled for corrected-part replacement at a later date.

状況
ベルクランクのボールジョイントソケット溶接部に溶接不良のものがあるため、据え切り等の繰り返し操作により、当該溶接部に亀裂が発生するものがある。そのため、そのままの状態で使用を続けると亀裂が進行し、最悪の場合、当該部が破損してボールジョイントソケット部が抜け出し、操舵不能となるおそれがある。
改善措置
全車両、ベルクランクを対策品と交換する。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ボールジョイントソケット部を点検し、亀裂のある場合は対策品と交換し、問題のない場合は後日対策品と交換する。
