Disco 2 crunch coming from drivers front wheel area

Hi all

Advice needed please
car passed its MOT around 5 weeks ago ,it had the upper and lower drivers ball joints replaced,but also had a advisory ref anti roll bar bushes getting worn

thing is now i have a crunch from that side every time im going slow and go over anything like a speed ramp or a curb

any one have any ideas of most likely part thats gone?????

cheers

Is it a knock?

Could be the drop links

more like a crunch ,metal on metal kind of noise

wondering would i maybe be able to find the problem if i lift the front need up?and if so would i need both sides lifting

its really ****ed me off to be honest as car had been running spot on

how do you test a drop link???

hold it while someone rocks the car
