ARB bushes

[racerboy59]

How do I know if my anti roll bar bushes have failed? On visual inspection they look ok, all in place and holding the anti roll bar securely in position. But i'm experiencing a clunking sound when going over speed bumps and rough roads.

I have a Mazda RX8. It's done 47,000 miles and first registered May 2004. I find that the sound disappears if I drive over the speed bump with only the right wheel, whilst keeping the left wheel flat on the ground. The noise happens as soon as the left front wheel hits a bump. This leads me to believe its something in the front suspension.

Ahh well heres the thing. I've been experiencing this problem for a few months and after it being originally diagnosed as droplinks, i got them replaced. But the same problem remained.
I think if the ARB bushing has gone soft then the ARB itself might be making contact with the chassis, therefore causing the clunking over bumps. I've ordered powerflex bushes anyway. We'll see what happens after I get them fitted.
