Defect / Noncompliance Description
For this Defect/Noncompliance:
Describe the defect or noncompliance: On certain vehicles, the tie rod clamp may be loose due to the
supplied lock nuts being over-crimped. This can cause thread galling of the bolt and nut during
installation. When galling occurs, it is possible that assembly torque may be achieved but the clamp is
still loose.
Describe the safety risk: The tie rod clamp being loose could lead to the threaded tie rod ends becoming
loose and eventual steering loss if the rod end pulls out of the tie rod, or the tube is broken due to
vibration of the loose joint.
Identify any warning which can precede or occur: Decrease in steering response

Chronology of Defect / Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the
noncompliance decision:
Late December, 2020, despite a lack of warranty claims and any other indications of failures on customer
vehicles, DTNA’s axle assembly plant in Mexico reported a tie rod clamp nut quality concern and
promptly began a containment effort. January, 2021, DTNA discussed with the tie rod supplier the
concerns, and the supplier established what it believed to be a “clean” date for tie rods assembled with
properly crimped clamp nuts. No information suggested that the problem extended further, and all
indications were that no defective parts escaped the production plant. February 2021, DTNA’s axle
assembly plant in Detroit reported finding similarly suspect parts and promptly began containment.
March 2021, DTNA resumed discussions with the supplier on this issue to understand scope of issue.
Early May 2021, DTNA received DFMEA from the supplier suggesting a potential safety concern. May
2021, even though DTNA is not aware of any field failures related to this concern nor has any
information to suggest the existence of a defect with an unreasonable risk to the safety of any vehicles in
the field, DTNA decided to conduct a voluntary safety recall.
Identify the Remedy
Describe the defect/noncompliance remedy program, including the manufacture’s plan for
reimbursement. Tie rod clamp bolts and nuts will be replaced. Repairs will be performed by Daimler
Trucks North America authorized service facilities. Details of the reimbursement plan will be included in
the owner’s notification letter.

IMPORTANT SAFETY RECALL
Subject: Tie Rod Clamp (Lock Nut) Over-Crimped
Tie Rod End Clamp Bolts
Models Affected: 2, 3 & 5 DETROITTM Front Steer Axles
This notice applies to your vehicle
This notice is sent to you in accordance with the requirements the Motor Vehicle Safety Act.
Daimler Trucks North America LLC, on behalf of its DETROITTM Powertrain Division, has decided that a defect,
which relates to motor vehicle safety, exists on certain DETROITTM Model 2, 3 and 5 steer axles manufactured
between Dec 15, 2020 through Apr 14, 2021. DTNA is initiating Recall Campaign D21R7 to replace the tie rod
assembly.
The tie rod clamp may be loose due to the supplied lock nuts being over-crimped. This can cause thread galling
of the bolt and nut during installation. When galling occurs, it is possible that assembly torque may be achieved
but the clamp is still loose. The tie rod clamp being loose could lead to the threaded tie rod ends becoming loose
and eventual steering loss if the rod end pulls out of the tie rod, or the tube is broken due to vibration of the loose
joint, creating the risk of crash.
Records indicate that your vehicle has one of the affected steering axles.
Please contact an Authorized DTNA Repair Facility and arrange to have the recall campaign performed. The
labor time required to perform this replacement is 2.5 – 2.6 hours. To locate an authorized facility, search online
at https://demanddetroit.com/find-a-dealer. This service will be completed for you at no additional cost by a DTNA

within 10 days. If you are a subsequent stage manufacturer, Federal law requires that you forward this notice to
your distributors and retail outlets within five working days.
You must make an appointment with the repair facility, at least two weeks in advance of the actual repair,
so the repair facility can stock the replacement part(s) needed to complete this recall campaign. Failure
to provide advance notification to the repair facility may result in a delayed repair.

reimbursement. Requests for reimbursement may include parts and labor. Reimbursement may be limited to the
amount the repair would have cost if completed by an Authorized DTNA Repair Facility.
