just took out my rear lower control arms, i've got new bushings to replace the old ones, but having a heck of a time getting them out, any suggestions?

Air hammer and lots of oil.
It will take a while, but eventually they will vibrate out.

Might have to hammer on the arms close to the bushing---just a bit at a time all around.
and with the chisel attachment----you can pry and vibrate at the same time.

Put em back in the same way

Or if you don't have an air hammer, drill out the rubber. I used a 3/8 drill bit and put maybe 8-10 holes thru the rubber. Weakened it so I could push it out, then collapsed the outer shell with a hammer & chisel.

Use a propane torch on the metal sleeve and a sledge. It'll come out

damn, I suppose I should brace the arm so it doesn't collapse when I beat out the bushing and shell?

Nah, not that much effort is needed. :noway:
I just partially collapse the bushing's metal shell with the air chisle to relieve it's "pinch" and a couple whacks with a hammer will knock it out.

If you are worried about collapsing the bushing shell just carefully hack saw through the shell then it will collapse around the cut with less force, done it many times. Drill out rubber in the bushing first.;)

thanks for all the advice iended up drilling out the rubber hammering out the center sleeve, then cut the outer shell in two places near each inner end ,then with a drive pin i hammered out the rest, thanks again, oh ya i'm going to try someone's advice about putting the new bushings in the freezer for a day, then try hammering them in

freezing the bushing definitely makes a difference I just did it with all of mine. If you cut a piece of exhaust tubing so it fits in the arm it keeps it from flexing and bending when you try to get them back in.

I froze the new ones, pressed them in with a bench vise, then tack welded the flange at one spot to prevent backing out. Used a spacer on the arm to keep it from bending while pressing the new bushings in.
