Why Replace the Suspension Arm Rear Bush?

The rear bush of the front suspension arm is one of the highest-load bushes on the Abarth 500 and 595. It controls the fore-aft movement of the suspension arm under braking and acceleration, and its condition directly affects steering precision and suspension geometry consistency. OEM rubber bushes degrade over time — cracking, hardening, and losing their ability to control arm movement accurately. Symptoms of a worn rear bush include:

• Vague or imprecise steering feel
• Pulling under braking or acceleration
• Knocking or clunking from the front suspension
• Uneven or accelerated front tyre wear

Replacing with Powerflex polyurethane eliminates these issues and provides a bush that will outlast multiple sets of OEM rubber replacements.

Bush-Only vs Complete Arm Replacement

If your suspension arm is in good condition but the bush is worn, replacing the bush alone is a cost-effective alternative to full arm replacement. If the arm itself is damaged, corroded, or the ball joint is worn, a complete arm replacement is recommended instead — see our pre-assembled Powerflex arm kits:
