  STEERING:LINKAGES:TIE ROD ASSEMBLY

  Daimler Trucks North America, LLC (DTNA) is recalling certain 2012-2015 Freightliner Cascadia, Coronado, Business Class M2, 114SD, and Western Star 4900 trucks. In certain front axle, brake lining, and brake spider combinations, braking may cause high vibrations, resulting in early failure of the tie-rod tube.

  SERVICE BRAKES, AIR

  Daimler Trucks North America (DTNA) is recalling certain 2015-2017 Freightliner M2 Business Class, 108SD, and 114SD vehicles. The affected vehicles might not have a required check valve installed in one of the ports of the spring brake modulation valve. Without the valve, the primary air system is not isolated from the secondary air system.

  Risk: A rapid loss of air pressure in the secondary system could cause a similar rapid loss of pressure in the primary system, which may lead to a sudden application of the parking brakes. This could increase the risk of a crash.

  Remedy: DTNA will notify owners, and dealers will inspect the vehicles, installing a check valve, as necessary, free of charge. The recall began on August 24, 2017. Owners may contact DTNA customer service at 1-800-745-8000. DTNA's number for this recall is FL-740.

These vehicles specify a front axle weight limit that may be greater than that of the hub capacity. As a result, the hub may fail and the wheel may separate from the axle.

  Risk: If a wheel separates from the axle, there would be an increased risk of a crash.

  Remedy: DTNA will notify owners, and dealers will replace the front axle hubs, free of charge. The recall began during November 2016. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-718.

The rear disk brake caliper may have been installed incorrectly, thus allowing the caliper to contact the suspension.

  Risk: Caliper contact with the spring suspension may reduce the braking effectiveness, increasing the risk of a crash.

  Remedy: DTNA will notify owners, and dealers will correct the orientation of the rear brake calipers, as necessary, free of charge. The recall began on June 8, 2016. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's recall number for this campaign is FL-705.

The affected axles have hex nuts on the flange yoke that may not have been properly tightened.

  Risk: If the hex nuts are not tightened to specification, the driveshaft may disconnect from the drive axle, resulting in a loss of propulsion and increasing the risk of a crash.

  Remedy: DTNA will notify owners, and dealers will inspect the hex nuts, tightening them as necessary, free of charge. The recall began on February 5, 2016. Owners may contact DTNA customer service at 1-800-745-8000, or Marmon-Herrington customer service at 1-800-547-0712. DTNA's number for this recall is FL-699.

In the affected vehicles, when the transmission shift lever is moved from reverse to neutral, the reverse gear may stay engaged. When the transmission shift lever is moved from reverse to a forward gear position, the transmission may mechanically lock because both the reverse gear and forward gear are simultaneously engaged.

  Risk: Even though the transmission has been shifted out of reverse into neutral, the vehicle may unexpectedly move backwards, increasing the risk of a crash.

  Remedy: DTNA will notify owners, and dealers will inspect and repair the affected transmissions if necessary, free of charge. The recall began on November 24, 2015. Owners may contact DTNA customer service at 1-800-745-8000. DTNA's number for this recall is FL-693.
