Filing in context
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 49 Mitsubishi notifications from 2008 in this archive. For scale, 3,312 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 years and 3 months.
Defect
On large route buses, the routing of the air lines and power steering lines is improper, causing those lines to contact the underfloor support members at the rear of the body. Continued operation allows vehicle vibration to damage the power steering lines, causing an oil leak. As a result, steering effort may become excessively high.
Corrective action
On all vehicles, inspect the clearance between the lines and the underfloor support members. Where clearance is insufficient, replace the line mounting brackets with corrected parts. Where the lines are already damaged, replace them with new units.

状況
大型路線バスのエア配管及びパワーステアリング配管の配置が不適切なため、当該配管が車体後部の床下支持材に接触するものがある。そのため、そのままの状態で使用を続けると、車体の振動等により、②パワーステアリング配管が損傷し、オイルが漏れ、ステアリングの操舵力が過大となるおそれがある。
改善措置
全車両、配管と床下支持材との隙間を点検し、隙間が狭い場合には、配管の取付金具を対策品と交換する。また、配管が損傷している場合には、配管を新品に交換する。
