- Summary
- On certain heavy duty class 8 trucks equipped with air suspension proprietary axles and adjustable lengh torque rods, an interference between the adjustable torque rod and the brake chamber on the left side of the chassis may exist. The spring brake chamber clamp ring could possibly be distorted over time resulting in loss of air, which could lead to the spring brake at the chamber being inadvertently applied.
- Consequence
- Braking capability would be diminished, increasing the risk of a crash.
- Remedy
- Dealers will repair and replace the adjustable torque rod, with a fixed length torque rod, inspect and repair the brake chamber free of charge. The recall began on may 3, 2005. Owners may contact mack trucks at 610-709-2131.

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.
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.
