20390840 Cabin Mounting — Volvo FMX FE Series trucks — FH400

This cabin mounting is engineered to isolate the driver's cabin from chassis vibrations and road shocks, enhancing operator comfort and reducing fatigue. It is constructed from high-quality materials to meet rigorous OEM specifications, providing superior damping and durability compared to a worn or collapsed mounting. Operators may notice increased vibration transmitted into the cabin, excessive noise, or a feeling of looseness in the cabin structure when this component begins to fail.

Installation & Application Notes

Torque all suspension fasteners to specification — under-torque causes wear, over-torque causes fatigue cracking. Replace bushings in pairs. Grease all zerks after fitting. Check alignment after suspension work.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The initial symptom of a failing cabin mounting is an increase in vibration and noise felt within the driver's cabin. If ignored, this can lead to significant operator fatigue on longer journeys and potentially cause stress on other cabin-related components. Continued operation with failed mountings can compromise the overall structural integrity of the cabin.

Installation Tip

Ensure all mounting surfaces are clean and that the correct alignment is maintained before tightening fasteners to prevent uneven stress. Avoid using excessive force, which could damage the mounting or the cabin structure.

Service Note

Inspect the cabin's subframe and attachment points for any signs of cracking or deformation during the replacement of the cabin mountings.
