Upper Ball Joint came out while driving

Question. If he does actually weld the ball joints in. Wouldnt he have to hope that those ball joints last the life of the car. It would seem like alot of work to grind off the spotwelds later and also risk warping the control arm re-welding it, no ?
I tac welded mine in place,the threads were still there but getting worn.I had a wet rag handy for cooling down after tacking.My car is for 1/4 mile only,not a daily driver,so I should be fine.Unless they pop out after wheelies?LOL:toothy10:
