Are you DIY'ing the ball joints themselves? I might send them an invoice for my own personal labor at $100/hr considering that no one around here will touch my rig. If you do and they approve, let me know! If not I'll be the guinea pig .I’m about to swap out the other ball joint with a Moog K500018 to match what we fixed on the side that failed. From everything I’ve seen the upper arm is fine they just used an inferior ball joint. Once I get the other upper ball joint done I should be good. Then I’m sending Ironman a bill for labor and for an alignment.
