ok im doing a engine swap and we have everything all done and put back to geather spet the lower ball joints in the front. every time we go to spin them the whole ball joint spins threds everything. so i have to Bang it bank into place and it will stop spings???

 

use a pickle fork on it and that should tighten it up enough to make it stop spinning. If not cut it off and replace them


EDIT: I thought you were trying to get them off. But if you are putting them back on use a impact to put it back on. But bump the trigger on the impact when putting it on

 

Lower the car down or jack the LCA up and it should keep it from spinning. Your joints may be wearing out, so check them for play.
