Overview
| MLIT filing number | 1104190 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | June 29, 1993 |
| Manufacturer(s) | Hino |
| Component | Power steering |
| Production period | December 1991 — June 18, 1993 |
| Vehicles affected | 4,568 units |
Defect
On vehicles equipped with a power steering system for dual-front-axle configurations, the hydraulic hose for the auxiliary sub-booster — which reduces steering effort for the second front axle — was installed in an excessively bent condition on certain vehicles. Repeated full-lock steering maneuvers may damage the hose and, in the worst case, cause power steering fluid to leak, resulting in a severe increase in steering effort.
Corrective action
On all vehicles, replace the hydraulic hose and, on U-FW series vehicles only, replace the sub-booster with the corrected parts, and add a hydraulic pipe.
