2018-2021MY Isuzu FTR Vehicles
This bulletin supersedes previous campaign bulletin CB22-E-001. This bulletin is being
revised to correct the torque specification for the adapter base. Please discard previous
campaign bulletin CB22-E-001.
INFORMATION
CONDITION
Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in
2018, 2019, 2020 and 2021 model year F-Series vehicles. The jam nut for the steering stopper
bolt on the left side may loosen and allow the bolt to back away from the steering knuckle. This
could result in an increase in the turning radius of the vehicle in left turns, which could make it
difficult to make sharp turns. If the vehicle’s turning radius is increased, there is an increased
risk of a crash. A prior recall (19V-467) was conducted to address this issue, but we have
identified this condition on vehicles that were remedied in that campaign as well as those that
were produced after a change in production intended to prevent the condition.
CORRECTION
Isuzu dealers will replace both right and left side stopper bolt assemblies, which include new
Spiralock Nuts, and torque the new Spiralock Nut to a new specification. This service will be
performed free of charge.
VEHICLES INVOLVED
Involved are 2018, 2019, 2020 and 2021 model year FTR vehicles.
NOTE: It is not necessary to open a TAL case or generate a health report in order to
submit a warranty claim for this campaign.
Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Isuzu
Vehicle Inquiry System (IVIS).
For dealers with involved vehicles, a report of involved vehicles containing the complete vehicle
identification number has been or will be provided. Dealers will not have a report available if
they have no involved vehicles currently assigned.
PARTS INFORMATION
An initial supply of Stop Bolt Assembly Kits will be shipped to dealers. Additional Stop Bolt
Assembly Kits may be ordered from American Isuzu Parts Distribution Network (AIPDN).
Please refer to your “involved vehicles listing” before ordering parts. Normal (non-emergency)
orders should be placed on a Stock Order. In an emergency situation, parts should be ordered
on a VOR (Vehicle Off Road) Order.

properly, snug the Spiralock Nut with a ¾” open wrench. Using a ¾” deep well
socket and a torque wrench, tighten the Spiralock Nut to the specified torque.
