- The spring center bolt is not the proper size or length. As a result, location and alignment of the spring to the front axle may not be correct. If the front spring clips loosen, the inadequate center bolt may result in spring to axle misalignment, shifting of the axle, and loss of steering control.
- Remedy
- The defect will be corrected by the addition of a spacer between the spring and the center bolt head to increase the effective head length. A longer center bolt will also be installed for positive retention.

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.
