What car do you have?

They prolly didn't know what to do so they decided to take appart the lower control arm that mounted the your braking system where the axle mounted to so that they cab slide the shock&spring assembly in easier. Arg.........I don't know what the terms or how to call it, but they shouldn't do that. Anyways, just re-insert the axle to the assembly, it shouldn't be a pain in the a**. Just becareful and NOT TO hammer the axle really hard.
