Anyone DIY removed rear subframe bushes?

Has anyone removed their rear subframe bushes without the use of a press or a proper tool like the HPA one?

I've bought AKG 75d rear bushes to replace the current ones and on my e36 I burnt them, drilled holes and then the metal ring with a saw blade. Has anyone taken the e92 m3 bushes out in a similar manner (bar using a saw blade).

Unfortunately I'm located in the UK so hiring a tool is much harder and I don't trust the local shops here to use a hydraulic press without damaging the subframe.

We have seen it done with a torch and air hammer. First you will need to burn the bushing material out, then use an air hammer to split the bushing shell, but this is really a backyard mechanic process.

Thanks Harold, your feedback is much appreciated. I'm considering buying a 12 or 20 tonne press so might leave it a for a while until I can source one at a reasonable price. I've used that same process for my e36 and it is a horrible job with the smoke and smell.

It's worth buying the bushing tools. I've done many sets and the correct tools make the job so much easier!

If you have the subframe completely out of the car, you can certainly use a press to remove and install the bushings.

I removed mine with a 6" two arm gear puller. The rears came out fairly easy because the hooks on the puller can grab the sub-frame fairly easy. On the fronts I had to use a large C clamp to span and hold the hooks tight since its hard to get much bite on the subframe. In both cases you will also need a small plate that will fit over the hole in the bushings that the screw on the puller can push against. I used a 1.5" diameter x .25" thick piece I had.

I also heated the subframe a bit to release the rubber. Just warmed it up. Did not damage the paint. Took about an hour.

I replaced the bushes on mine on the drive, I lowered the subframe enough without disconnecting the brake pipes etc and used a few things I had laying around, (bearing cases, gearbox syncro sleeves etc!) and some threaded bar and nuts and penny washers to enable me to pull out the old bushes and pull-in in the new ones.

When I remove large bushings or wheel bearings, I use a big washer the size of the bushing shell, a short piece of pipe big enough for the bushing to slide into as it's coming out, and a big bolt, washer or plate with hole to cover the end of the pipe, and a nut to create an at-home press to pull out the bushing. Often times, the new one can be pulled in in a similar fashion.

Yes, it works on all E8x and E9x chassis.

No, you must drop the subframe to go the bushings regardless of M or not.

At least enough to get a bushing tool in there to removed the bushings. I say at least 10-12", that means disconnecting the two brake hoses.
