Summary of Issue

A fleet of Car Haulers (CRC Transport) received a citation for "Hubs - No visible or measurable lubricant showing in the hub - outer wheel". The suspension is a grease filled hub with a solid hubcap. The grease cannot be seen.

Justification or Need

This is not a new design. Grease filled hubs with solid hubcaps have been used on trailers for many years (>20). Drive Axles have utilized solid hubcaps for decades.

Request for Action

Add clarification language to OOS 14(i)(5) to differentiate and clarify hubcap styles and ability to see lube/grease.
