POWER TRAIN:DRIVELINE

Issued by PACCAR Incorporated · Reported Jul 21, 2023 · 72 vehicles affected

What's wrong

PACCAR Incorportated (PACCAR) is recalling certain 2023-2024 Peterbilt 536, 537, 548, 2023-2024 Kenworth T280, T480, and 2024 Kenworth T380 vehicles. The adhesive thread-lock may not have been applied to the four flange mounted yoke bolt threads, allowing the driveline fasteners to loosen.

Consequence

Loose fasteners may allow the driveline to separate from the truck, increasing the risk of a crash.

Remedy

Dealers will apply adhesive thread-lock and replace the fasteners, free of charge. Owner notification letters are expected to be mailed September 19, 2023. Owners may contact PACCAR's customer service at 1-425-828-5888 (Kenworth) or 1-940-591-4220 (Peterbilt). PACCAR's numbers for this recall are 23KWE and 23PBE.
