Bulletin Summary
Parts and repair procedures are now available. Certain Kenworth model T380 and T480 chassis equipped with a Meritor 10-16K or 18-23K Front Steer Drive Axle have been identified as possibly having insufficient wheel bearing grease. Insufficient lubrication in the wheel bearing may cause the wheel hub to overheat and become damaged, which may increase the risk of a thermal event. The driver may observe noise, excessive steering play, and/or smoke from the front wheel.
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.
