I've got a 1999 1.2 fiesta thats had new front suspension top mounts and also ARB D bushes. After a test drive there is still a rattle coming from the front. Checked the lower arms which are fine, and the track rod ends, but something is making a noise.

After more investigation the noise is coming from the drivers side front wheel area. Shaking the wheel, in the traditional way doesnt produce any noise. In fact the lower arms, top mounts and ARB check out fine. In a moment of frustration I kicked the tread on tyre which produce a definate metallic clunk. Other than outer CV joint (which does not make the usual noises) and strut road, what's left to check.

Any ideas?

I can't help with the Fiesta but my son's Saxo had a rattle on the driver's front wheel when lifting off the throttle.

I checked everything and couldn't find it - so I replaced the driveshaft and that cured it.

It didn't sound anything like the normal CV joint noise.

I got the complete driveshafts from HERE for £32 each with a three year guarantee.

They will probably do them for the Fiesta

Thanks. I really can't convince myself it is the driveshaft as it doesnt make the usual CV 'click' noise when cornering etc. It also only makes the noise on rough tarmac. It is not a 'rotational' noise or a noise affected by speed, but a random metallic chatter, two metal components hitting together. I've worked on a few KA's and Fiesta's over the last 6 months and have become quite an expert on issues with 'top mounts' and 'lower arms' but this noise is different. I cant find anyone who can confirm that a driveshaft or carrier bearing can rattle over rough ground when worn but not make noise otherwise Confused

Anti roll bar links?

Turned out to be the mounting bolt for the drivers side lower arm slightly loose? It was tight, but not fully torqued up. All done Very Happy
