I purchased Elephant Racing poly bronze bushings for the rear. I spent a ton of time and several broken drill bits removing the stock rubber from one trailing arm.
This task was a big PIA.
Is there another way, for those who don't have a 20-ton press, to remove these bushings? Any advice is appreciated.

Have you tryed heating with a propane tourch to melt / burn the rubber out of the arm ?? The propane tourch shouldn't get the metal too hot to ruin the heat treatment of the shaft and arm. (IMG:style_emoticons/default/blowtorch.gif)

yes, I applied heat and had them smoking. Worked great for the front, but not so great for the rears I am working on.
The elephant set comes with special shafts, so I am not worried about getting those hot. I did not want to use heat on the painted surface 'cause I don't want to repaint, but it's too late now!

Here's what I do. They come out smoothly. No broken tools, no cursing, 20 minutes for both sides.

Yes, they are a pain to get out! I found that my 2 favorite tools helped a lot

After heating, I pounded the thing (pulling looks nicer). Then I used a razor blade to cut out what was showing of the bushing. This helped get more access for the heat to melt away the bushing inside. It took like 2 hrs to do the first one, 1 hr to do the second one. Good luck (IMG:style_emoticons/default/beerchug.gif)

Mark,
So are you pushing the rod through the bushings and out the other side of the swingarm?

This is exactly what I did , pushed the shaft out one side , got the bushing out , put the puller / pusher on the other side pushed the shaft back through the bushing and then removed that side using heat from a propane tourch - both sides done (IMG:style_emoticons/default/piratenanner.gif)

McMark: (IMG:style_emoticons/default/pray.gif) You saved me hours on the second trailing arm. So why does Chuck at Elephant recomment drilling the bushings out?
To anyone doing this job. DO NOT DRILL, use McMarks method. Minutes compared hours...

Now what?

Pushing out the hubs with a 12 ton press and bang! Hub came out taking one of the bearing races with it, on each side!! (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) Attached Image

Figured Eric would have the answer!

Bet I'll need the dremel as hard as the hubs came out!! Sounded like an explosion when they finally "fell" out!!! Damn they were under a lot of pressure!!!

Installing rear bearing video won't work- hopefully just a temporary problem...

Yep a 12 ton HF that looks like the one in one of your videos... used it to pop out the hubs along with one of the bearing races (IMG:style_emoticons/default/smile.gif)

I simply press the shafts out. As follows:

1. Set the shelf at the 4th hole from the top. Heat the shaft with a MAPP torch (the threaded section sticking out from the bushing) until there are wisps of smoke from the rubber.

2. Press the shaft through the first bushing.

3. Using the largest flat head screw driver you can, pry the rubber bushing up and out from the inside. Go back and forth and you'll see it move upward and eventually out. Not hard at all.

4. Drop the shelf to the 5th hole down.

5. heat and press the shaft through the other bushing. Get the shaft very hot so it can press through the bushing without binding. Otherwise the bushing can bind and go into the arm.

6. The press will not have enough travel to get the shaft through the second bushing. Move the shelf back to the 4th hole and finish the job.

7. Repeat step 3.

Very easy. No mess. Not much stink. Yada, yada, yada...
