Knocking on Front Offside Discovery 4

I have a knocking on the front drivers side when driving over bumpy terrain. I have had all the joints checked and the mechanic has said he can't find any worn joints. Has anyone experienced similar or know of a common fault? The disco is a 2011 and has 120k miles on the clock.

TIA

Two main areas, anti toll bar bushes even if they look okay change them, or the lower susepnsion arm bushes have died.

I just had similar, it was the drop link from the end of the anti-roll bar to the upper control arm, Item No 30 on page 313 section 204-01 Front suspension, when you get play in the ball joint it just knocks, but you may not feel any movement until it removed totally, one of my ball joints on the rear was totally snapped but as it just stayed in the cup could not be seen on a ramp, only found it as I had to remove the shocker to check if it wa the problem, and had to drop the axle to refit the shocker the ball came out of it housing total separation, so I just replaced the all

Thank you for the information chaps, very much appreciated. I'll update the thread as soon as I have got the knocking sorted. Will update asap.

It turned out to be the lower suspension arm. New one fitted and back to normal now. Thanks for the guidance chaps .
