20429148 Bump-Stop — Volvo FMX FE Series trucks — FH400

This bump-stop is an essential component of the suspension system, designed to absorb impact and prevent excessive suspension travel, thereby protecting other components from damage. It is manufactured to OEM quality standards, offering superior resilience and longevity over worn or collapsed stops that can lead to harsh impacts. Operators may experience a rougher ride, bottoming out of the suspension over bumps, or hear loud noises from the axle area when this part is failing.

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 first indication of a failing bump-stop is often a harsher ride quality, with impacts feeling more severe than usual. If left unaddressed, the suspension may repeatedly bottom out, leading to potential damage to shock absorbers and other suspension linkages. The worst consequence is damage to the chassis or axle components from repeated, uncontrolled impacts.

Installation Tip

Ensure the mounting surfaces are clean and free of rust or debris before installing the new bump-stop. Avoid using excessive force or leverage, which can damage the new component.

Service Note

Inspect the shock absorbers and suspension springs for any signs of damage or premature wear when replacing the bump-stop.
