Affects Peterbilt 385, 320, 379, 378, 357 · 2001 — about 2 vehicles.
The hazard
Certain Peterbilt Class 7 and 8 tractors with interaxle driveshafts produced and supplied by Spicer Driveshaft, Inc. (SDI). The SDI driveshafts with universal joint cap bolts were not tightened to SDI's full torque specification. If the driveshaft assembly became separated from the retaining bolts, the interaxle could be ejected from the truck's driving axles, resulting in hazardous debris. This could occur with little or no prior warning to the vehicle's driver, and could also result in loss of vehicle power. Correction: Dealers will re-torque the retaining bolt fasteners.
