Upper control arm question

You can remove the old ones with a good vise and an air chisel/hammer. ust a flat blade and hold it so that the flat end is parallel with the axis of the bolt and start at 180° apart. Then 90° until you collapse the outer sleeves enough to drive them out.

To install try using a sleeve over the smaller end that gets pushed through. Grease the **** out of the smaller part of the shell that contacts the control arm. Then on the other side, use another sleeve/socket that presses down on the outer shell portion and crank down with your vise. The trick is not to push on the inner part, only the outer part for the outside, and not contact the other end while pushing them in.
