'Fraid it's not as easy as it could be to just replace all the bushings...
Factory bushings are not avail., as they are installed in a "one time" manner - nice & secure in there but not replaceable. Std. factory fix is replacing the arms complete - they're relatively inexpensive & at shop rates this is actually cheaper than replacing bushings.
Aftermarket has performance Poly bushing kits available which CAN be backyard installed, however a press or some skill with a good vise is the minimum to be able to do it.
The largest PITA most run into (especially on cars that have seen winter) is that the bolts rust into the bushing sleeves making removal whole nearly impossible. Once thoroughly frozen in the bushings most posters have reported having to cut the bolts for removal. In some cases even having to cut off the tack welded captured nuts if the bolts can't be turned free. ( if you get them to turn B4 cutting you could unscrew the remnants afterwards, many don't put that much effort into saving the tack nuts)
The simple appearing job turning difficult due to the "Rust Monster" is the reason most just replace worn out items (in pairs recommended) OR go "Whole Hog" and re-bush the entire rear end.
LCA's (lower control arms) would be the first place I'd look for sacked bushings if wiggle was starting to be an issue.
