Check towing eye for bending, excessive wear and/or deformity. Contact Tronair for
repair/replacement if towing eye is bent, excessively worn or deformed.
•
Check towing eye mounting bolts. Ensure fasteners are not loose or missing. Tighten to 25 ft-
lbs or replace as required.
•
Ensure that the towing eye does not turn; if the towing eye can turn it indicates that the
centering pin within the shock assembly may have been broken and repairs are needed.
•
Check the shock assembly for preload on the spring by pulling on the towing eye. If the shock
can be moved by hand it indicates that the spring is worn out and Tronair should be
contacted for repairs.
