View Full Version : Is it possible to press out rear differential bushings?

Planning on having my subframe chemically immersed to remove the rust, but I would like to keep the original rear differential bushings (pictured below). Has anyone successfully removed them without damaging either the bushing race or subframe? I've read there were concerns with this happening when removing the subframe bushings, but not the differential bushings. Thanks in advance!

why would you keep them if you gonna remove the whole subframe? if you going to rebuild, then you might as well rebuild everything. besides you will need new bushings for toe, camber, etc and diff bushings are about $40 bucks. you dont want to keep anything that has been pressed in, like rubber or urethane...it damages over time with weathering and removing them without damaging is impossible unless they are solid bushings.

The multilink bushings are part of the control arm/toe/camber/traction arms. The only bushings on the subframe are the 4 subframe bushings and these 2 differential bushings. I'm going to use ES polyurethane bushings on the subframe itself and switched to a s13 differential where the nose is solidly mounted to the subframe. To maintain some quietness in the car I'd rather use the OEM bushings which are still in good condition. The alternative to this would be use the Megan Racing hard rubber bushings, but that's money I'd rather not invest when the OEM ones are still ok.

What I'm concerned about though is the possibility of the subframe collapsing before those bushings come out. From what I've read, everyone burns the bushings out and cuts the bushing race instead of pressing it out.

It may be possible, but seriously difficult. You would need to get a pusher the exact size of the bushing. Then use something like a ball joint tool to remove and install them. There is no way to fit the subframe in a press as far as I can imagine.

Go rent a bearing/bushing press kit, they have tons of sizes you can get real close to the bushing and press out. I've done a number of control arm and subframe bushings this way.

That looks like one of the pieces for the front of the diff.



I don't see how you could press them out without damaging them. You're better off torching the rubber and cutting the outer ring/sleeve and just replacing the bushings. I know Energy Suspension sells polyurethane ones for that location.... or just go solid.
