Knock From F/os Suspension

[JohnPic]

Have an O3 Alhambra 145,000 miles, new to me last summer. 

Have a knock going over bumps from the front off side suspension.  Not all bumps but most.  It does not relate to steering just to a bump.  I have had a look and cannot see anything obvious. 

I have replaced anti roll bar bushes - which has greatly helped the handling but not the noise.

Have replaced the drop link, which seemed fairly OK and no improvement at all.

 

Does anyone have any suggestions of what to check and how to check.  Car is in the open and maintenance gets done in the open, been OK so far!

Shock absorber top mount if badly worn or could be the shock absorber itself making the noise.

Also rear bush in wishbone has a tendency to split and part, allowing wishbone to whip up and down on bumps within fixing recess. You get a good rattle when that happens.
