Steering: critical fasteners

22V27700017,641 vehicles affected

The problem
PACCAR Incorporated (PACCAR) is recalling certain 2018-2020 Kenworth T270, T370, T440, T470, T660, T680, T880, T800, W900, W990; and 2018-2020 Peterbilt 330, 337, 348, 365, 367, 389, 520, 567, and 579 vehicles. The Dana D-Series axle steer arm fasteners that attach the steering arm to the steering knuckle may fail.
The risk
Fastener failure can result in a loss of steering control, increasing the risk of a crash or injury.
The fix
Dealers will replace and torque the steer arm fasteners, at no charge. Owner notification letters were mailed November 8, 2022. Owners may contact Kenworth customer service at 1-425-828-5888 and Peterbilt customer service at 1-940-591-4220. PACCAR's numbers for this recall are 22 PBB and 22 KWB.
