General Information
Daimler Truck North America LLC (DTNA), on behalf of its Freightliner

Campaign SF660 to modify the vehicles mentioned above.
On certain vehicles, the drag link tapered joint, at the steering arm, may not have been tightened to

in separation of the joint leading to a complete loss of steering, which could lead to a crash.
The drag link will be inspected and torqued to specification. Repairs will be performed by Daimler Trucks
North
America authorized service facilities.
There are approximately 59,039 vehicles involved in this campaign.
NOTE: Only approximately 2% replacement is expected. Please do not overstock replacement parts.
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.
Please contact Warranty Campaigns for consideration of additional charges prior to performing the repair.
