Anti-roll bar bush or mounting worn
How it can appear on an MOT certificate
- “Anti-roll bar pin or bush worn”
- “Anti-roll bar mounting insecure”
What it is
Rubber bushes hold the anti-roll bar to the car's body. Like other bushes, they perish over time.
Why it matters
Worn bushes can cause creaks and knocks and let the bar move about, reducing its effect. An insecure mounting is a fail.
What to check when viewing a car
Listen for creaking or knocking over speed bumps. This is usually a straightforward repair.
