General Information

Daimler Trucks North America LLC (DTNA), on behalf of its Freightliner Trucks Division, and wholly owned subsidiary, Western Star Truck Sales, Inc., has decided that a defect that relates to motor vehicle safety exists on the vehicles mentioned above.

On certain vehicles, the steer axle spindle nut snap ring may not be fully engaged. If the snap ring becomes dislodged, it may not prevent the spindle nut from backing-off causing the hub to loosen and potentially cause a wheel-off condition, increasing the risk of a motor vehicle crash or injury.

The snap ring will be inspected for proper installation and repaired as needed. Repairs will be performed by Daimler Trucks North America authorized service facilities.

There are approximately 1,677 vehicles involved in this campaign.

 

Additional Repairs

Dealers must complete all outstanding Recall and 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.

Replacement Parts

Replacement parts are now available and can be obtained by ordering the kit and/or part number(s) listed below from your facing Parts Distribution Center.

 

Spindle Nut Snap Ring Procedure

1. Inspect the base label (Form WAR259) for a campaign completion sticker for FL866 (Form WAR260). If a sticker is present for FL866, no work is needed. If there is no sticker, proceed with the steps below.

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

3. Place an oil drain pan under one of the steer axle hub caps.

4. Remove the capscrews, washers, and hub cap.

5. Remove and discard the hub cap gasket.

6. Inspect the snap ring for proper installation. The snap ring must be installed in all of the grooves all the way around the spindle nut.

The top two snap ring tabs should be in line and close together. The lower tab should be fully installed in the locking hole in the spindle nut.

For examples of incorrectly and correctly installed snap rings, see Fig. 1, Fig. 2, and Fig. 3.

 

7. Confirm the snap ring is properly seated in the spindle nut groove. If the snap ring looks like Fig. 1 or Fig. 3, ref. A, install the snap ring correctly in the grooves.

8. Confirm the locking tab is fully installed in the spindle nut locking hole.

If the snap ring looks like Fig. 4, go to step 9.

If the snap ring looks like Fig. 5, go to step 10.

9. Completely remove the snap ring and tighten the hub spindle nut 300 lbf·ft (407 N·m). If the hub spindle nut moves at all, remove the hub and check for damage; replace the hub if it is damaged. For replacement instructions, see Group 33 of the applicable workshop manual.

If the hub spindle nut does not move, install the snap ring.

10. Clean the area where the hub cap gasket will be installed.

11. Install a new hub cap gasket and the existing hub cap. In a star pattern, tighten the capscrews 15 lbf·ft (20 N·m).

12. Remove fill plug and fill hub with oil, then install the fill plug.

13. Repeat steps 3 through 12 on the other steer axle wheel.

14. Clean a spot on the base label (Form WAR259). Write the campaign number, FL866, on a blank red completion sticker (Form WAR260) to indicate the work has been completed, and attach it to the base label.
