Howard’s Mack trunnion service includes trunnion shaft replacement, trunnion tube work, and trunnion bar work. He does not perform trunnion bushing or trunnion stand replacement.

The Problem

When a Mack Trunnion Shaft Needs Replacement

Trunnion shaft damage develops for several reasons. Wear elsewhere in the assembly, poor lubrication, damaged bushings, cap problems or other component failures can contribute to shaft wear or damage over time.

Those related conditions are important context because they may explain why the shaft failed. Along with trunnion shaft replacement, Howard also performs trunnion tube and trunnion bar work. Trunnion bushing and trunnion stand work are not offered.

If another shop or technician has already identified the shaft as the failed component, call Howard with the truck information and location.
