Potential Number of Units Affected 5,641

 

Summary

Trail King Industries, Inc. (Trail King) is recalling certain 1992-2023 TKFA, TKPA, AB, and AB EXT trailers equipped with pin-on axles or pivot extensions. The shims that transfer weight between the trailer and the pin-on axle may detach if the air line or air suspension lose compression.

 

Remedy

Dealers will install new shims, tether, and hardware to tether the shims to the pin-on axle or pivot extension, free of charge. Owner notification letters are expected to be mailed September 8, 2023. Owners may contact Trail King customer service at 1-800-843-3324. Trail King’s number for this recall is TK202301.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.

 


IMPORTANT SAFETY RECALL

This notice is sent to you in accordance with the requirements of the Motor Vehicle Safety Act. This is to inform you that your vehicle may contain a defect that could affect the safety of a person.
This notice relates to the shims used on Trail King Flip Axles, Pin-On Axles, Air Boosters, and Booster extensions. Trail King has determined that a safety defect that relates to the shims used in the front of the units involved could become loose if the flip or booster loses compression.

 

What Trailers are being recalled?

This recall affects Trail King Flip Axles, Pin-On Axles, Air Boosters, and Booster Extensions manufactured dates of January 1992 through August 2023 model years that use removable shims between the unit and the unit these attach to.

 

What is the Problem?

The affected trailers use additional pin-on axles or pivot extensions installed at the rear of the trailer to extend the trailer’s load-carrying capacity and more evenly distribute weight over the trailersaxles. The pin-on axles and pivot extensions are attached to the trailer by lower pins and use shims to compress against the trailer at the top. The shims are used to transfer weight between the trailer and the pin-on axle. If an airline or the air ride suspension under the trailer or pin-on axle experiences a sudden failure (e.g., struck by road debris) and becomes disconnected, the pin-on axle or pivot extension could suddenly lose compression with the trailer allowing it to shift suddenly. In this event, while there is no loss of control of the trailer, the shims could become loose and ultimately dislodge from the connection point.

 

What should you do?

Obtain and confirm your trailer’s serial number from the VIN plate located on the driver’s side of the unit. You are receiving this letter because our records show you are the current owner of this vehicle.

 

What will we do?

Trail King Industries is conducting a safety recall campaign to address this issue. Trail King will provide new shims, tether, and hardware to bolt to the trailer. Trail King will provide up to 1 hour of labor and replacement parts necessary to remedy units. The repair will be provided on all affected trailers free of charge. Please contact your nearest Trail King Industries dealer to have your trailer inspected and repaired. You also can contact Trail King Industries directly at 1-800-843-3324 and our Customer Service Department will help you locate a dealer near you. We will send the parts needed to the dealer to repair your trailer.

Please note, it is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by the notification under a sale or lease until the defect or noncompliance is remedied.

 


Chronology :

On June 16, 2023, Trail King received a report from a customer that a shim located between a loaded heavy-duty trailer and the pin-on axle had detached while the trailer was in operation and with a pilot car following behind the load. The customer reported that a shim was projected into the air and into the front of the pilot car following the load.

Because of this event, Trail King initiated an investigation to determine if this condition was an isolated incident or potentially a broader issue. It was determined that the suspension supply line of the trailer had suddenly and unexpectedly become disconnected (possibly struck by road debris that severed the line), causing the air in the flip axle to quickly release, resulting in loss of compression on the shims. Trail King has been manufacturing trailers with the same pin-on axle and pivot extension design for decades and is not aware of any similar reports. Through the investigation, it was identified that with a unique chain of events such as the customer described the possibility that the same or similar chain of events could happen again could not be ruled out. Although no injuries were involved in this incident, Trail King thus decided to proceed with a recall.

On August 8, 2023, Trail King decided to conduct a recall for this issue.
