thats a track rod end
springs look nice and new so im guessing recently lowered
worth a shout at whovere did it as if they didnt cause the damage they propbably at least noticed it or they just havent tightened it properly
if it is shagged and loose itll be seized most likely and needs replacing asap as it controlls the steering of that wheel so if it comes of that wheel will turn wherever it wants and youll end up in a hedge/bush/fence/lampost ect ect
not a hugely hard part to sort they just screw out the track arm but setting the tracking back up after if your not sure i wouldnt attempt
best bet is off down the garage for a quote matey
