The defect
PACCAR Incorporated (PACCAR) is recalling certain 2020-2021 Peterbilt 348, 365, 367, 389, 520, 567 and Kenworth T800, T880, W900, W990 vehicles equipped with Watson and Chalin steerable lift axle suspension systems (model SL2065). The axles may have lower rear pivot bolts that are not long enough to sufficiently engage the locking feature of the corresponding nuts.
The risk
The short screws can cause the hardware to separate from the suspension system and become road hazards, increasing the risk of a crash and/or injury.
The remedy
PACCAR will notify owners, and dealers will inspect suspect chassis and replace the pivot bolts, as necessary, free of charge. The recall began September 29, 2020. Owners may contact Kenworth customer service at 1-425-828-5888 and Peterbilt customer service at 1-940-591-4220. PACCAR's numbers for this recall is 20PBE and 20KWC.
