You should just be able to pop it back in. I have never seen this, but one of my rears popped out and I just popped it back in. Try taking the coilover out so that theres no tension on the lower control arm, this will allow alot of free movement. When you do this, you will have a better shot at popping it back on. Try putting alittle WD40 on it. Hope this helps.
