Correct, those are the wrong bushings. The correct rubber bushings are not rotatable.
On the originals the sleeves are part of the bushing. Molded together. It's a tough installation. In fact you may need a heavy press to do it with AND you need the special tool to hold the a-arm in the press while you do it. There is very little "meat" on the knuckle to hold the arm with.
The poly-urethane bushings however will slip right in now.
They don't squeak any more then the rubber bushings do but are grease-able where as the rubber ones aren't.
The rubber also will split eventually as well.
