lower control arm pivots

Ok so maybe I should have worded my question differently. I know how to get the lca bushings out. Its the pivots that I wanted to know if I could use my air hammer to knock out from the back where the torsion bar slides in. Doesnt really matter now though cause all I did was f*%k them up...so guess I will have to wait a little longer now. And the wife wonders why I wanna trade all my junk for something thats already done :banghead:
