Service bulletin 24PBF

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

SAFETY RECALL Repair parts and procedures are now available. Certain Peterbilt vehicles from Model Year 2025 may contain steering gear(s) with sector shaft gear teeth that may prematurely wear, crack, or fracture and interfere with the steering gear mechanism. This may lead to steering gear binding, which may increase the risk of a crash.
