I am attempting to remove my original ball joints.the upper I can handle by grinding off rivet heads but does anyone have any tips on how to remove the bottom ones without removing the lower control arm from the car? 2nd Gen

 

The lower ones seemed easier to me to remove than the uppers. BTW, if you are interested, I currently have brand new MOOG heavy duty lower ball joints that will fit the same as stock replacement ones that I am selling. These would be much better than stock ones, and also are cheaper. Let me know if you are interested, I can cut you a deal.
