Filing in context
The Suspension Arm/Rod is the most frequently cited component category in this archive, appearing in 24 of its 4,890 filings. This filing is one of 27 UD Trucks notifications from 2020 in this archive. For scale, 3,360 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 3 months.
Defect
On large trucks equipped with multi-leaf spring suspension, the V-rod center joint ball sleeve and flange may be insufficiently engaged due to an improper manufacturing process. Repeated large load variations, such as crossing road irregularities, reduce the clamping force of the bolts securing the flange. This causes the center joint housing to fracture and, in the worst case, may compromise vehicle driving stability.
Corrective action
Replace the V-rod on all vehicles with a corrected part.

状況
重ね板ばね式緩衝装置付大型トラックのＶロッドにおいて、製造工程が不適切なため、センタージョイント部ボールスリーブとフランジとの嵌合が不十分なものがある。そのため、段差乗り越えなどの大きな変動等を繰り返し受けると、フランジを固定するボルトの締結力が低下し、センタージョイントのハウジングが破損して、最悪の場合、走行安定性が損なわれるおそれがある。
改善措置
全車両、Ｖロッドを対策品に交換する。
