Another front end knock thread! Changed everything!

Hi guys, I've read through the many knocking threads!

I have had many different front end noises. Car done 140,000 so no surprises.

Had a lower arm knock first, then the upper arm bushes failed and gave a knock/graunch.

Changed lower and upper arms. Changed the anti roll bar bushes and the drop links as well. They looked original and ropey.

Changed the track rods and the track rod ends.

The driveshaft gaiters were starting to split so ended up changing both driveshafts for new items as well just for the hell of it.

Still have a knock when small bumps and when weaving left/right.

Does anyone know what else the knocking could be?

I'm not sure there's much left? There's a rubber bush at the bottom of the air suspension strut, do these knock at all?

Thanks

I had to change the lower steering column shaft to cure a front end knock, it was picked up at the MoT.

Just in case anyone was wondering, the knocking has stopped now.

I changed, front anti roll bar bushes with new rubber spacers underneath them, both lower arms, both upper arms, both driveshafts, both track rods and ends and the lower steering column shaft.

And both front anti roll bar drop links.

It doesn't knock anymore, at least from the front end!
