- Summary
- The driveshaft to the front driving axle is secured to a bracket using two pillow blocks. These blocks are of insufficient strength to support the driveshaft and could fail.
- Consequence
- Pillow block failure allows the driveline (jackshaft)to drop down onto the roadway and create a safety hazard to other vehicles.
- Remedy
- Mack will install thicker pillow blocks and support u-bolts.

Has your Mack 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 Mack dealer can also check your VIN. Recall repairs are free.
