All good advice, thanks.
I have pulled the brakes apart, not changed the tyres - even a rotate would change things.
The IND reported:
- definitely nothing wrong with the wheel bearings
- can't find any movement anywhere apart from the LHS inner CV which has a little but seen much worse
- can't hear it while driving .... hang on WTF?? Did you turn right and get up to 80? Yes, nothing...
And this is the interesting bit. As I drive off towards home, the clicking is gone, quiet... for about 8-10km and then it comes back over the next ~2km.
So next day I give them a call and the old guy who runs the place says bingo - and goes on to explain why its gone quiet after they pulled/pushed/prodded everything - which unfortunately I didn't follow as I not seen one apart.
He has recommended waiting until it gets more obvious just to be sure. Apparently they won't just let go.
After a heap of web searching the symptoms match results for inner CV issues - although I didn't find any for an L322.
