What Does It Do?

The stabiliser bar bush holds the anti-roll bar securely against the chassis while allowing it to twist as the suspension moves.

The anti-roll bar helps limit body roll during cornering, improving vehicle stability and handling response.

Why Is It Important?

Worn bushes can allow excessive movement of the anti-roll bar, affecting suspension refinement.

Common symptoms include:

• Knocking or rattling from the rear suspension
• Increased anti-roll bar movement
• Squeaking over bumps
• Reduced suspension precision

These symptoms may also be caused by worn drop links or other suspension components.

Why Do Stabiliser Bar Bushes Fail?

Over time, the rubber can deteriorate through repeated suspension movement and exposure to road conditions.

Common causes include:

• Rubber hardening or cracking with age
• Compression and loss of elasticity
• Wear from anti-roll bar movement
• Contamination from oil, dirt or road salt

When Should It Be Replaced?

Replace the bush if it is cracked, excessively worn, distorted or no longer grips the anti-roll bar securely.

Inspect both rear bushes together, particularly when investigating suspension noises or replacing anti-roll bar links.

Installation Notes

Confirm the anti-roll bar diameter is 18.7mm before installation.

Clean the mounting area and inspect the anti-roll bar for corrosion or wear. Fit the bush correctly and secure the retaining bracket using Porsche's specified tightening procedure.
