Corteco – Hydro Bushings – Technology Note

Hydro Bushings – Technology Note
A technical leaflet on hydro bushings for chassis isolation, comparing dual‑rubber and hydro layouts. It explains how fluid‑filled bushings achieve frequency‑dependent damping, reduce steering wheel vibration, and improve ride comfort without sacrificing control.

Overview
Fluid-filled bushings deliver frequency-dependent damping to isolate targeted NVH bands without compromising control.

What’s inside

• Hydro vs. solid bushing comparison and durability considerations.
• Orientation marks and preload instructions.
• Typical symptoms (shudder, steering nibble) and diagnosis flow.

Installation tips

1. Press using correct adapters; never deform the outer shell.
2. Align witness marks; torque at normal ride height.
3. Reinspect after 100–200 km for settling where specified.
