On the front? You should be loosening the nut. You may be able to just tap the bolt out once the nut is removed. If you’re lucky like me, they'll be rusted in place and you'll end up beating on them with a hammer for 5-10 minutes a piece to get them out and have to buy replacements Also, you should mark how the camber washers are oriented before you remove them so you can get your alignment at least close after reassembly.
.....you should remove the nut and tap out the bolt....f.y.i. ...the bolt has a groove in it that lines up with a groove in the cams/washers...if things aren't lined up you'll never get the bolt out....look closely and you'll see what i mean....i found out the hard way when i did my l.c.a.'s..
You might wanna try a 21mm standard socket. A deep well socket might slip when you put alot of pressure on it. Just a suggestion
neither of them worked real well, the standard socket wouldn't fit over the bolt protruding from nut, and the deep socket wouldn't clear the tie rod, so i used standard on the bolt side and adjustable on nut side.
