Should the bottom Anti-roll bar bush bolt have this much free movement? I've got a terrible knocking at the front , just replaced the front antiroll bar links and found the bolt was like this. I'm wondering if the bush has worn or the knock is elsewhere

 

With the anti-roll bar bush in situ, there should be no movement of the bolts.

Check the lower strut bushes as they tend to perish and can cause a knocking sound. Also check the bushes on the upper and lower suspension arms for wear, and the tie rod ends for any looseness.

 

The arm bushes are all ok, I replaced them all couple of years ago. The bush in the video is one of just 2 that I didn't replace, the other being the large bush on the end of the lower arm. I would hope the bushes haven't failed already as they were genuine Jaguar and cost an arm haha. Tomorrow i will try disconnecting the antirioll bar links and drive it around the block to see if the noise vanishes
