NHTSA campaign 19V176000
Hazard
PACCAR Incorporated (PACCAR) is recalling certain 2020 Kenworth T680, T800, T880, W900 and W990 trucks. The rear axles may not contain oil.
Consequence
Without lubricating oil, the bearings, hub and axle shafts may wear, resulting in the separation of a wheel end from the axle, increasing the risk of a crash.
Remedy
Paccar will notify owners, and Kenworth dealers will inspect all of the rear axles for the presence of oil. If no oil is present, the wheels ends will be removed and the bearings, hub and axle shaft will be inspected for damage. If excessive wear or heat damage is evident, the components will be replaced, as necessary. Oil will then be added per the axle specifications. These repairs will be performed free of charge. The recall began April 16, 2019. Owners may contact Kenworth customer service at 1-425-828-5888. Paccar's number for this recall is 19KWA.
