Thanx for the idea on the specs being off....that did come to mind.Ill prolly check that out today. But ya. The upper ball joint is definitely harder to change but can be done. You really just have to figure out a creative way to get that press in there the right way. For me...I figured saving a
good 100 more dollars at least in getting the control arms too, that I didnt need, was worth burning a very small hole on the top of my wheel well to fit in the screw for the press, which I was able to turn from the inside of the engine.
If the specs are correct and its just the dimension of the hole on the knuckle, any ideas on how to take a mm or so off cast iron? I know the metal is very hard and abrasive, so I'm not sure what I should machine it with. Definitely not High Speed Steel.
