I would not rush to change them......well not the front anyway.
Backs can be changed by pulling the disc, knocking the studs back and fit new ones, torque and re-torque again after driving.
Re the fronts. As the hub needs to be pulled, so calliper, grease seal, pull and either clean or fit new bearings makes it a lot of work for something that may never happen, and the normal mode is it is the rears that fail more often than the front, I would replace a front set if in there with other maintenance you may be doing, a bearing or a birf ect.
Just a note, I seem to remember the stud length is different front and rear?
Might be worth having a chat with
@beno?
