Filing in context
The Spring / Air Suspension is the most frequently cited component category in this archive, appearing in 27 of its 4,890 filings. This filing is one of 140 Mitsubishi notifications from 2005 in this archive. For scale, 2,954 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 5 years and 1 month.
Defect
On the leaf-air combination suspension, the mounting structure and tightening torque of the U-bolts securing the leaf spring to the front axle are incorrect. During cornering and similar maneuvers, excessive twisting force is applied to the U-bolts, causing cracks to develop. Continued use allows the U-bolts to fracture and, in the worst case, the suspension may shift off the front axle, compromising driving stability.
Corrective action
On all vehicles, inspect the U-bolt mounting components. If the corrected parts have not been installed, replace the U-bolts and mounting components with corrected parts. If corrected parts are already installed, replace the U-bolts and nuts with new ones.

状況
リーフ・エア混合式サスペンションにおいて、リーフスプリングとフロントアクスルを固定するＵボルトの取付構造及び締付けトルクが不適切なため、旋回時等に当該Ｕボルトに過大なこじり力が発生し、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、Ｕボルトが折損し、最悪の場合、当該サスペンションがフロントアクスルからずれて、走行安定性が損なわれるおそれがある。
改善措置
全車両、Ｕボルトの取付部品を確認の上、対策品未装着の場合には、Ｕボルト及び取付部品を対策品と交換する。すでに対策品に交換されている場合は、Ｕボルト及びナットを新品と交換する。
