Core support dog bone bushing removal (the easy way)

Looked for awhile and didn't see any posts on this so I thought I would share my positive experience while contributing to the forum.

First step - buy poly bushings. The rubber ones were worn, and my removal method will not work for install. I suppose, if one was so inclined, you could make your own as well. But, I was at ZZP anyways so in the name of f*ck it, I bought a set.

This process is easiest to do one at a time. Leaving one side hooked up keeps the engine oriented and makes the job simpler in my opinion.

Step 2 - remove a dog bone, and find a ratchet strap.

Step 3 - tie a figure 8 or clove hitch or similar non slipping knot on the bolt head end with the hook side of the strap. I prefer the figure 8 as it takes up less space and always tie a safety knot to prevent unwanted slippage. I also used a spare section of strap left over from a tail I shortened for a marine application.

Step 4 - insert bolt into bushing with nut on exterior facing side. Attach ratchet end to opposing dog bone core support mount or other stable location.

Step 5 - run strap through ratchet and start cranking. Once you get good tension on the bushing make sure the strap is firmly secured to the bolt and won't slip over the bolt head. Then continue tightening until the bushing begins to tear. After that physics pretty much handles the rest and the center section will rip enough to allow the rest of the rubber to fold up and flop right out. If you wish to make it interesting you can keep cranking away until it flies out but I aired on the side of caution in this case.

Step 6 - install new poly bushing and reattach dog bone.

Repeat mirror process for opposing side.

Start to finish this way took me a good ten minutes. Not accounting for the half hour of fiddle f*cking around with other unsuccessful methods.

I'll try this method when the times comes. Not a bad idea. I've heard of cutting them out, chiseling them out, and one guy on here said he melted them out... However, this approach seems like it gets the job pretty cleanly and efficiently.

I tried cutting them with a buck knife. A sharp one. Images of busted up knuckles or sliced open fingers from slipping kept me from using too much force and it was just not something I felt comfortable continuing along with. Bleeding out is not my favorite past time.///// I don't see how chiseling rubber is even possible. And I tried ripping chunks off with pliers and it worked but after 10 mins of cutting, pounding, ripping and wasting time...... I hadn't even made it halfway through the top part.///// Melting........ Yeah....... Firefighter here. Not a fan. If your 3.8 leaks flammable engine lubricants like mine does.......lighting rubber on fire near that front valve cover just doesn't seem like that great of an idea.///// my method works, is clean, and requires little to no effort. Just have to know how to tie a good knot.
Fiddle Fvcking is one of my favorite pastimes....
Mine too. But I have to go back to work next week and I don't have the time to waste anymore. Layoff season is over. It's crunch time.

I just used my jigsaw to cut across the top and bottom of the mount. Pulled out the metal center, lifted out the rest with a flat head screwdriver.

Easier? Maybe with a small jig saw. Smaller blades would probably make it easier. But I didn't have one, and I wasn't gonna buy one for this.

As far as safer, I was patient and used just enough tension for the rubber to start giving. And I stayed on the side away from the pull. I fully trust my knot tying capabilities as a firefighter I have to be good with them as I might have to trust my life to a knot I tied in the dark with gloves on.

I just used this method (except I was exceptionally lazy and I just wrapped the ratchet strap around the core, used some lube (always necessary), and POP! Think it look me maybe two minutes? Glad I found this post before I did this. Nice work!
