Chronology :

Terran received two (2) customer complaints (July13 & 14, 2021 respectively) related to reported wheel vibration in one instance and friction causing smoke to emanate from an axle in another instance on trailers utilizing our axles. Beginning at 7pm on July 14,2021 Terran initiated a manual quality control review of the available axles in there manufacturing plant. The objective was to identify and manufacturing or assembly issues, with the axles, any safety risks and necessary repairs, replacements or adjustments. They enlisted their internal axle specialists and visually and manually inspected 125 axles to identify any axles that did not meet specification.

After assessment of this data with advice of internal axle specialists, they determined on July 17,2021 to initiate a notice of repair to their trailer manufacturer and their customers. The email was received that Terran axles required inspection of all axles to determine immediately if the spindle nuts were properly torqued. Terran management prepared written instructions for the necessary spindle nut torqueing along with step-by-step instructional video. On July 21, 2021 Terran management made a formal determination that remedial field action was necessary. Carson Trailer sent recall letters to all customer involved on January 12, 2022.
