Field Service Campaign
February 2014
SF488A

Subject: Airliner 69K Axle Stops
Models Affected: Specific Freightliner 108SD, 114SD, Business
Class M2, Cascadia, and Coronado vehicles; and Western
Star 4700 vehicles manufactured October 1, 2012, through
July 15, 2013, equipped with 69K Airliner suspension.

General Information
Daimler Trucks North America LLC (DTNA), on behalf of its Freightliner Trucks Division and wholly owned
subsidiary, Western Star Truck Sales, Inc., is initiating Field Service Campaign SF488A to modify the vehicles
mentioned above.
On certain vehicles the axle stops may be too long creating an incorrect suspension ride height. An incorrect
suspension ride height can result in out of spec driveline and axle angles, which could adversely affect u-joint life.
The axle stops will be replaced with axle stops of the correct length.
There are approximately 215 vehicles involved.
Additional Repairs
Dealers must complete all outstanding field service campaigns prior to the sale or delivery of a vehicle. A Dealer
will be liable for any progressive damage that results from its failure to complete campaigns before sale or delivery
of a vehicle.
Owners may be liable for any progressive damage that results from failure to complete campaigns within a
reasonable time after receiving notification.
Please contact Warranty Campaigns for consideration of additional charges prior to performing the repair.

Work Instructions
Please refer to the attached work instructions. Prior to performing the campaign, check the vehicle for a completion
sticker (Form WAR261).

Replacement Parts
Replacement parts are now available and can be obtained by ordering the kit number listed below from your facing
Parts Distribution Center.
If our records show your dealership has ordered any vehicle(s) involved in campaign SF488A, a list of the customers
and vehicle identification numbers will be available on AccessFreightliner.com. Please refer to this list when ordering

Work Instructions
Subject: Airliner 69K Axle Stops
Models Affected: Specific Freightliner 108SD, 114SD, Business
Class M2, Cascadia, and Coronado vehicles; and Western
Star 4700 vehicles manufactured October 1, 2012, through
July 15, 2013, equipped with 69K Airliner suspension.

Axle Stop Replacement and Rear Suspension Ride Height Adjustment
Vehicles equipped with dual ride height control valves follow the same procedure as single valves, but with two
height gauge blocks and both height control valves adjusted simultaneously. Both linkages should be disconnected
when adjusting and both valves should be repositioned once the correct ride height has been reached on both
sides.
1. Check the base label (Form WAR259) for a completion sticker for SF488 (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, using a light application of the brakes. Shut down the engine, set the
parking brake, and chock the tires.

3. For each rear axle stop, remove the existing axle stop and replace with the stop and fasteners provided in the
kit. Tighten the nuts 136 lbf1ft (184 N1m).
4. Build the secondary air pressure to at least 100 psi (690 kPa). Shut down the engine.
5. Space the tire chocks 2 inches ahead and behind the tire so the vehicle can roll 2 inches in either direction.
6.

Release the parking brake and verify by hand that the vehicle can roll forward and aft. This should remove
any load from the suspension.

7.

Disconnect the height control valve linkage at the lever stud. (For dual valves, disconnect both.)

8.

If there is not enough room for the block between the axle stop and the top pad, lift the valve lever to inflate
the airbags enough to fit the block. (For dual valves, lift both arms.) Do not install the block yet.

9.

Pin the arm in neutral position with a 5/32-inch drill bit or nylon rod. See Figure 1. (For dual valves, pin both
arms.)

10. Install the height gauge block. (For dual valves, install a block on both sides.)
11. Unpin the valve lever and use it to lower the suspension until the axle stop rests on the block. (For dual
valves, unpin and lower with both valves.)
12. Move the arm to neutral and pin. (For dual valves, pin both.) The vehicle should now be at the target ride
height.

NOTICE
When loosening a Barksdale height-control valve from a mounting bracket, always hold the valve-side
mounting studs in place with an Allen wrench while loosening or tightening the nuts that attach the
valve to the bracket. Because the mounting studs are threaded into the valve body, loosening the nuts
without holding the studs can tighten the studs, which can crush the valve body and damage the valve.
Conversely, tightening the nuts without holding the studs can back the studs out, causing a separation of
the two halves of the valve body, and possibly a leak.

13. While holding the height-control valve mounting studs in place with an Allen wrench, loosen the nuts that
attach the valve to the mounting bracket. See Figure 2. (For dual valves, loosen both valves.)

stud in place with an Allen wrench when

14. Adjust the position of the valve body until the lever—still pinned in neutral position—can connect to the linkage.
Attach the linkage. The linkage rod should be vertical, and the valve body should now be in the correct position
for the vehicle’s ride height. (For dual valves, adjust and connect both.)
If the linkage cannot reach the stud, check the surrounding components for bent or damaged parts and remedy
as needed.
15. While holding the height-control valve mounting studs in place with an Allen wrench, tighten the nuts 95 lbf1in
(1100 N1cm). Do not overtighten, as that could damage the valve. (For dual valves, tighten both.)
16. Disconnect the linkage from the valve arm stud. (For dual valves, disconnect both.)
17. Raise the valve arm to raise the suspension enough to remove the block, then pin the valve arm in neutral
position. (For dual valves, raise and pin both valves.)
18. Remove the block. (For dual valves, remove both blocks.)
19. Remove the pin or drill bit holding the height-control lever in neutral position, then connect the valve arm to
the linkage. (For dual valve, unpin and connect both valve arms.)
20. Drive the vehicle unloaded for about 1/4 mile (1/2 km), then park the vehicle on level surface using a light
brake application. Chock the tires on one axle only, and put the transmission in neutral. Do not apply the
parking brakes.

21. Check the ride height of the vehicle again. See Table 3. If the distance is within the acceptable range, the ride
height is correctly set. Apply the parking brakes.
If the distance is not within the acceptable range, repeat the adjustment procedure.

22. Clean a spot on the base label (Form WAR259). Write the campaign number, SF488, on a blank grey
completion sticker (Form WAR261) to indicate the work has been completed and attach it to the base label.
