Control Arm Bumper

It's not hard to do at all.
All that you need is a thin wall 9/16 deep socket, 1/2 inch drive, or if you can beg, borrow, steal, buy, a 9/16 deep socket , 1/4 inch drive that will fit up there between the two halves of the LCA.
Don't see where your having a problem with a 1/2 inch drive socket.
