Service bulletins for the 2020 Kenworth T880
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| A003 | 2020-11-05. Service bulletin. POWER TRAIN; STEERING. PACCAR has determined that all Set Forward Front Axle (SFFA) models with the PACCAR 20K front steer axle and wide-based tires have the potential to experience a shimmy or shake in the front axle. Wide-based tires include any series tires with widths of 385 mm or higher. This is due a lack of friction in the current axle rotating components. Replacing the thrust roller bearing with a thrust washer assembly creates enough friction to eliminate the shimmy. |
