Cheers for the info.

Check for worn drop links and upper strut bushings.

Thanks Rokit, Everything is new, I even have Powerflex polly bushes installed on the control arm, yes, firmer ride, not by much and feels more M3 than X5 in the corners but then again my bushes in the CA where shot. So any new part would feel amazing. Everything is tight underneath now, and no issues. I am a happy camper because nothing more embarrassing then pulling up at a set of traffic lights in a nice car only for a loud, clunk as you come to a stop.

They were way loose compared to the prescribed torque
Before you do anything to find a wobble or front end noise, make sure everything has been tightened corrlectly. This was the source of months of frustration and some unnecessary spending before I found the culprit

So three years later, I'm chasing a similar problem - a sharp click I can hear and feel through the floor every time I hit the brakes. Definitely from the lower front right side. Checked calipers, front thrust arm etc. - nothing. Used Google to search Xoutpost and found my way back to this thread, shot outside and checked the lower control arm inner bolt. Not loose but maybe only 50-60Nm. Torqued it up to 100Nm and bingo! - noise gone.

Odd, as I've never touched this bolt. I did remove the left-side bolt when I changed the CV boot on the left a few year back (and I re-checked that today - still at 100Nm).

Quoting myslef here but for clarity, this DIDN'T fix my noise issue. It was gone for a day or two, so I thought it had...

I now think it's poor quality brake pads - they seem to have some free-play within the pad carrier and can move appreciably when the brakes are applied - creating a click.

Looking to swap out the pads for some Bendix DB1409-Euro+ pads to see if that cures it.

*edit* the Bendix pads DID cure it - the cheap pads were a loose fit in the calliper and moved eerytime I hit the brakes...
