Front wheel clonking

hi,
I have a 2000 x reg 1.8 Freelander with 63k done. When i turn on full or near full right lock quite quickly round a slower corner (make sense?) I get a clonking noise from the front passenger side.
I first got this the day after I had a manifold fitted by, as it turns out, the local butcher. When I eventually got under the car to investigate I found the front subframe? that holds the sump guard in place only held on with 3 out of 6 bolts. Also the sump guard rivets had been drilled out and the guard was just resting in there, and the drivers side wheel arch liner was held in by 1 bolt.
Ive rectified all this and the clonking was instantly dramatically reduced, although it is still there.
At first I thought it was the subframe banging the chassis, but now Im thinking CV joint, but why did it improve after I tightened the subframe bolts up? The exhaust doesnt seem to hit the bodywork either. Its just passed its MOT with no mention of CV trouble.
Im Confused! Any suggestions please.......

Yeah, you know how it goes though, deny, deny, deny, it was already like that sir.
But I was more thinking along the lines of mechanical suggestions!

Are you sure that it front the front passenger side and not from just under where the gear select is?

If it sounds like its from there it is probably the VCU bearings that have given up. They usually start making a noise on tight corner, both ways, but not when reversing.

Nah, 99 per cent sure its from the front passenger side. From what ive read about the VCU thing it doesnt sound like that, i have no tightening up when turning.
Its the whole quietened down when i did the subframe thing which puzzles me.
