Almost 50,000 Kenworth and Peterbilt trucks are being recalled after a steering-related issue was discovered.

Paccar is recalling more than 47,000 Kenworth and Peterbilt trucks of various models because certain steering gears may have been assembled with fewer than the required number of recirculating balls, according to National Highway Traffic Safety Administration recall documents 

The following Kenworth models are affected by the recall (all model years 2024-25):

  • L770
  • T280
  • T380
  • T480
  • T680
  • T880
  • W990

The following Peterbilt models are included in the recall, also model years 2024-25:

  • 389
  • 520
  • 535
  • 536
  • 537
  • 548
  • 567
  • 579
  • 589

A steering gear with fewer than the required number of recirculating balls may bind when loads are applied. In some cases, the balls may align on the same side of the gear’s worm shaft and concentrated loads may cause the gear’s internal parts to fracture, resulting in a loss of vehicle steering. Loss of steering increases the likelihood of a crash.

Paccar dealers will inspect and replace the steering gears as necessary, free of charge.

Notification letters to owners of affected trucks are scheduled to be mailed out on March 25.
