These could actually be rubber, as it says; according to my book, I put a set of Dormans on the Red Cougar in about 2004, and they died within 6 months.
(I keep a book with all my mods and replacement parts, so I know what works, what sux, and what's on what car.)
I Replaced them with factory stuff, after I joined here about that time.
I thought I posted on it, but I can't find one.
I had to go to the JY to get the washers, thus my comment above.
I also took those bushings, rods, etc, but they were wasted when I looked at them years later.
They've made changes; the sleeves were cheap thin sheetmetal, and the washers and bushings were crap also.
They were not rubber, they were hard plastic, so this is different.
Hell, it's been over 10 years; If everyone else had the same experience I did then, they HAD to change.
If the bushings are intact, but loose, I'd absolutely hit it with an impact and tighten it up.
You'll be destroying the sleeves to get them out, so I would avoid that if not totally necessary.
I put a piece of hard leather between the strut rod flats, and a big pipe wrench, and stuff the end of the pipe wrench into the ground, so it won't move.
The leather keeps from putting stress risers into the arm, and DO NOT put the wrench near any of the bends, just the straight section.
The alignment is really set by the center of the two nuts, so if it's loose, I'd measure the distance, and move both nuts toward the center, if possible.
This is fucking hard to do, as you can't get an impact on the inner nut.
