Ok today i was driving my car into my driveway. My lower castle nut came off! So i tried putting it back on but it wouldnt'. The ball joint kept spinning. The thread seems to be messed up. Do i have to get a new lower ball joint?? Or is this problem fixable without getting the new ball joint? I have an extra hub but the bushing on the ball joint is ripped. I dont know if its still useable? Thanks
