Western Star 4700 Recall 20V539: Suspension Bolts May Separate, Posing Crash Risk

NHTSA campaign 20V539, reported September 3, 2020, 103 vehicles potentially affected.

What this recall means for you

Certain heavy trucks with SL2065 steerable lift axles may have lower rear pivot cap screws that are too short to fully engage their locking nuts. Over time, the hardware can separate from the suspension system.

If the screws come loose, the separated hardware can fall onto the road as a hazard to other drivers and raise the risk of a crash and injury. Owners should watch for any sign of suspension trouble and avoid driving the vehicle if it appears damaged.

The repair is free. Dealers will inspect the lower rear pivot cap screws for correct length and replace the hardware as needed. Owners will be notified by the manufacturer, and you can contact Daimler Truckers North America customer service at 1-800-547-0712 (recall number FL-862). You can also check your VIN for open recalls.
