good trick for getting old spring bushings out

Discussion in '1973-1991 K5 Blazer | Truck | Suburban' started by **DONOTDELETE**, Aug 30, 2001.

    going to replace the busings on a set of rear springs i have and i used an 1 1/8 socket and ratchet extention and just pounded them out with my BFH. worked slick, took 20 min. tops. of course the springs were out and on my garage floor so that helps too. make sure the socket and extention are ones you're not fond of cause they wont look the same after. just thought i'd share, it's rare when old sh*t comes out easy!

    Front 52"s?, What bushings are you going with?- still haven't been down that road yet. What is the I/D of the spring eyes? (1 1/8?)

    Probably not good for the temper to subject the springs to the heat of fire.

    Socket method can be improved upon by drilling two or three 1/8" holes around the outside of the bushings.

    <font color=green>most of us have tried to pound them out,and drill,,and file and and and,, doesn't alway's work. fire seem's to be the key to getting them out quickly with out breaking your hand's,leg's,shin's or any other part of your body that was close to the 20 lb sledge you were using. it doesn't actually need to be that hot, the bushing being made of rubber burn fairly easily and just fall apart, the spring doesn't actually see extreme heat,or shouldn't i should say. i usually give a few tap's with a hammer first to see if i can get them out easily,but it's just soooo much easier to use the " blue tip wrench ". takes about 5 minute's.</font color=green>

    Yeh, they can be a bitch.

    Just wondering what the long term effects could be on something tempered like spring steel.

    Got a set of '74 fronts that still have the original bushings laying in the pile, and I'm thinking about taking the bushings out. Ought to be a real laugh riot! We'll see if I resort to the "blue tipped wrench" or not :D

    The flame from rubber or urethane won't exceed 450-500 degrees normally - It would take alot more than that to have an effect on spring temper, plus the bushing only needs to burn for a few seconds to be charred enough to remove easily. No worries as long as you don't get wild.

    <font color=green>yeah,,as with any steel like that, if you get it hot it's going to lose some strength, but i think that some of the guy's on here ( look's around ) have had them hot enough to fry egg's on and still are using them on their truck. it's all kind of a guessing game, you want to burn them but not get the spring so hot that it's glowing red, that would not be good for it at all, but enough to get the bushing's out shouldn't really do any harm that you'd ever be able to see. i would rather use a 40 ton press to do it though.</font color=green>

    I just give them a little shot of WD40 or starting fluid and use a lighter - rubber loses integrity in nothing flat.

    You definitely wouldn't want to heat the springs to a red-orange temperature as that is when you will start to anneal, or soften, spring steel. I think the temp is around 2000F, but is different for different steels, as you might imagine.

    That said, you can put a flame to the bushings long enough to totally annihilate the rubber long before the steel gets anywhere near that hot.

    So if you can get 'em out without the torch, cool. If not, don't be afraid of a little judiciously applied heat!
