Copy of Notice to Owners
Subject: Western Star 49X Airliner Rear Suspension
Daimler Truck North America LLC (DTNA), on behalf of its wholly owned subsidiary, Western Star Trucks Inc.,
is initiating Field Service Campaign SF656 A-M to modify specific model years 2021-2022 Western Star 49X
vehicles, manufactured September 16, 2020, through December 10, 2021.
Certain vehicles were built with an incorrect airliner rear suspension for their specific vocations.
The airliner rear suspension will be retrofitted to meet the demands of vocational services.
Please contact an authorized DTNA dealer to arrange to have the campaign performed and to ensure that parts
are available at the dealership. The campaign will take approximately 25 hours and will be performed at no
charge to you. To locate an authorized dealer, search online at NorthAmerica.DaimlerTruck.com/contact-us/.
Scroll down to “Locate a Dealer,” and select the appropriate brand.
This Field Service Campaign will terminate on June 30, 2024. Please make sure the campaign is completed
prior to this date. Work completed after this date will be done at the customer’s expense.
As stated in the terms of your express limited warranty, DTNA will not pay for any damage caused by failure to
properly maintain your vehicle. DTNA considers the work necessary under this campaign to be proper
maintenance and will, therefore, not pay for any damage to your vehicle caused by your failure to have the
repairs that are the subject of this campaign performed in a reasonable time.
Contact the Warranty Campaigns Department at (800) 547-0712, from 7 a.m. to 4 p.m. Pacific Time, Monday

Work Instructions
Subject: Western Star 49X Airliner Rear Suspension
Models Affected: Specific model years 2021-2022 Western Star
49X vehicles manufactured September 16, 2020, through December 10, 2021.

40K Airliner Rear Suspension Retrofit
1.

Check the base label (Form WAR259) for a completion sticker for SF656 (Form WAR261) indicating this
work has been completed. The base label is usually located on the passenger-side door, about 12 inches
(30 cm) below the door latch. If a completion sticker is present, no work is needed. If a completion sticker
is not present, proceed to the next step.

2.

Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.

WARNING
Never work under a vehicle that is supported only by jacks. Jacks can slip, which can result in serious
personal injury, death, or component damage. Always support the vehicle with safety stands capable of
supporting the weight of the vehicle.
3.

Raise the rear of the vehicle, and support the rear axle(s) with safety stands. Raise the vehicle so that all
weight is removed from the leaf springs, then securely support the frame with safety stands. For instructions to raise and lower the vehicle, see Section 00.06 of the 47X and 49X Workshop Manual.

4.

Remove the spider (anchor plate) assembly. For instructions, see Section 42.31, Subject 170 of the 47X
and 49X Workshop Manual.

5.

Remove the air spring assembly. For instructions, see Section 32.01, Subject 150 of the 47X and 49X
Workshop Manual. See Fig. 1.
