Has your Peterbilt been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Peterbilt dealer can also check your VIN. Recall repairs are free.

August 6, 2003NHTSA 03V288000132 vehicles potentially affected

Power train › Axle hubs

Summary
On certain heavy duty trucks, the locking tab that locks the outer spindle nut onto the spindle was not engaged or properly bent over.
Consequence
Failure to properly engage the locking feature into the nut could cause the nut to loosen which will eventually cause the wheel bearing to over heat and fail if undetected. If the loose nut is not detected, the outer end (tire, wheel and hub assembly) could become separated from the vehicle, increasing the risk of a crash.
Remedy
Dealers will inspect the hubs to determine if the locking tabs are properly bent. If the locking tabs are not bent, then dealers will inspect the appropriate components for premature wear and replace such components as required and properly secure the retaining nut by bending over the locking tab. Owner notification began September 17, 2003. Owners should contact kenworth at 1-425-828-5440 or peterbilt at 940-591-4201.
