So rear trailing arm bushings, advice?

[shp4man]

I've read that you can remove the rear wheels and take loose the shocks to install the polyurethane bushings in the rear trailing arms. Drill out the old rubber to remove the old bushings, lube the polyurethane new ones and reassemble. Pry out the trailing arms with a crowbar? Both at the same time, or individually?
Anything else? Surprises?

You're overthinking. Just do the work.
Any local mechanic shop has a press and will do the bushings for a few bucks.

I did one side at a time and I burned my old rubber ones out with a propane torch. That left only the outer metal housing of the old bushing intact which is what the poly ones are designed to slip into.

FYI Poly bushings can sometimes be noisy, something to consider.

I pressed mine in and out, but then I had them all the way out anyway to fix a crack in the bend. Old time welder that repaired the crack and boxed in the arms said he used to do that a lot because the local ranchers were always cracking them in that same place. You might do that while you’re down there if you use it to carry loads.
