Filing in context
This notification is a joint filing by 2 manufacturers: Hino & Toyota.
The Power Steering is the most frequently cited component category in this archive, appearing in 43 of its 4,890 filings. This filing is one of 12 Hino notifications from 2003 in this archive. For scale, 2,137 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 4 years and 6 months.
Issue
The hydraulic line attached to the power steering hydraulic pump is improperly routed. Engine movement during travel over rough or uneven road surfaces causes cracks to develop in the joint fitting at the line attachment point. Power steering oil then gradually leaks from the joint fitting, increasing steering effort required to operate the steering wheel.
Corrective action
On all vehicles, replace the hydraulic line with a corrected part.
