L322 suspension knock

Hi, I have a 2003 Range Rover

It has developed a single knock from the front nearside when turning right and another single knock when straightening up. Local 4X4 specialists have replaced some of the bushes on the front. They say the front control arms look OK and so havn't been replaced....could they be the problem, or am I looking at a bearing?

any help appreciated before I end up running out of money!!

I would defineatly look at the lower arm . Mine was exactly the same on my L322 . Replaced it , noise gone. Had tiny play in it but the noise was horrible !

Thanks for the reply. I have already had the lower arms replaced...

Sounds like a bush to me. But it is hard to tell which. Not much help then.
