Grassroots Motorsports LIVE! on Wednesday June 6: What’s the Best Way to Remove Bushings?

I don't know what the best way is, but I can say with some confidence that the guys in the photo should be using something other than a torch on that Miata.  Timely tale though, doing the job this weekend on mine.

Replaced every bushing on my Supra a few years back. I just looked through a couple hundred pictures of that process. Appears that I used a couple different hammers, a pry bar, a just-right-sized socket, a bolt and washer, a bearing puller, an air hammer, a hole saw, and quite a bit of PB'laster.

Everything but the hole saw worked wonderfully. Also, just looking at those pictures makes me a bit exhausted. Can look through them all in a few minutes, but all that work took probably 2 months!

Doing the job this weekend, will press them out and press new ones in using HF ball joint servicing tool

Do you have experience doing bushings with this tool?  I’m about to do an e36 rear subframe and will pick one up if it works well.

Be sure to heat the rear diff before attempting to press the bushing out.  On mine, the bushing was so stuck we cracked the diff cover trying to press it out!  

Sweet, a hammer and fire episode...

Just a bump since tonight's the night.

For that level of investment, I prefer this BMW-specific E36 tool kit:  PMD bushing/bearing press kit for E36 and E46

I bought mine AFTER I did my subframe bushings, so I can't promise it will get them done.  But it's the ONLY thing I know of that will do the outer control arm bushings quickly and without ever destroying the new bushing on reinstallation.  It does RTABs nicely, better than the Bimmerworld RTAB tool.  I even managed to use it to press in a rear wheel bearing, and that's a really tough job.

As for the subframe bushings, they are large diameter and very long.  The HF tool set doesn't have the long receivers and drive screws that I would need to deal with the subframe bushings.   The PMD kit doesn't have anything with a large enough diameter to do the job on its own.  But it has the length, and I would rather have that available while I kludged something together with an iron pipe nipple and a pipe cap as the press receiver.  Or more likely, I would borrow the AdvanceAuto Powerbuilt 23-piece balljoint/ujoint kit and see if the big receiver pipe in that set was large enough.  

I just did this two nights ago to get a LCA bushing replaced.

It worked pretty good

To remove the old one, I hammered out the center to break the rubber, then I cut sliced the ID of the shell with a hack saw (feed the blade through the hole first then re-assemble hacksaw). With two good slices in the ID of the shell, I was about to hammer and "screwdriver chisel" the shell out.

In reply to maschinenbau :

Reminds me of the time I used a 3 ton floor jack and 2x6's to help take the twist out of the side walls of an old 18' wide garage with a 16' wide over head door. 

Seriously though buying the Harbor Freight 12 ton shop press was a great investment.  Use it to replace all the bushings in my old FC RX-7 and it has come in handy ever since.  Recently had to press out the corroded in place hub bearing in the aluminum knuckles of my wife's Epsilon II based Buick turbo Regal.
