Re: Upper Ball Joint bolts
It's not going to hurt anything to drill the control arm out to 5/16th... It's not a big size jump... I would say stay with the grade 8 bolts as well... Don't use lock washers... Get regular washers and grade 8 lock nuts... I've seen way to many lock washers rot out or break and than you have a sloppy fit...

He was only worried (by the sounds of it) about the warranty if for some reason he needed to send the control arms back for warranty...
