Bulletin Summary
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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
