Inset both bushings into the drop links first. Then squeeze them on to the sway bar side, then onto the strut bolt. I used a little Gibbs (super penetrating oil) and the biggest pliers Harbor Freight sells To do that.
Each time:
Pinching the link with the bushing installed, onto the side of the ball, then rolling the pliers with the bushing and link, over the ball and towards the other side. It will pop on.
(Directly lined up, and squeezed never worked for me)
Boiling water will help when inserting them into the drop link. Still will have to work squeeze them in there.
