I’m willing to bet tacos, it would end up being more expensive to pay someone else to press out and press in all those bushings versus having them replace complete units.
I’d BALLPARK 2-3 hours labor to press them all out and in. Ballparking labor $125/hr, ballpark cost $250-375. What’s the price difference between all new assemblies and just bushings? I know on the LCAs at least, the difference is minimal. Something to consider
I can see where people can save money doing it themselves if they have a press, time and patience, but paying someone an hourly rate to do it might get costly.
Encapsulated Toyota bushings can be a massive and royal pain to swap out, even with the proper tools and especially if ya live in a rust prone area. So time to replace will vary, and if your paying by hour, you could be up a creek sans paddle
We have a big fancy press and all the fittings for it here and after replacing the bushings of the LCAs on my Tundra, I swore I’d never bother doing that again, opting to buy the complete assemblies instead from now on
YMMV
