    Rear Subframe Bushing Broke and Sleeve is still attached to Body

    Changing the rotten rear subframe bushings and while lowering the subframe - I broke both bushings right below the big top washer.

    The bushing sleeve is made of pot metal - it is rusted / seized onto the frame - it broke about an inch down - 1/2inch still inside the tube that runs into the body under the bench seat.

      Any thoughts on how I can remove the remaining sleeve?

      Can I push it out from the top using a thin socket - tapping the top of the bolt splined sleeve?










      Or is it better to drill it out - or chisel it out from the bottom?

        Drill into it and then take a cold chisel and get it to rotate inside the body. They come out very easy after that. The broken piece that is stuck in the body will probably crack and fall out after you run a bit all the way through it. There is no way to force it out from above.

          Find the correct size lag bolt (5/8 I think) and screw or up into the remaining material from underneath, then drive it out with a drift from inside the car.

          You will have it out in minutes with this method, rather than banging and chiseling away at it.

            the bushing sleeve is made of *aluminum*, not pot metal.

            the problem is if it's 25 years old and has never been replaced, it will rust to the body. yes, aluminum corrodes..

              5/8 is the correct size.

                      Also do you think there is some type of adhesive on this from the factory? Look at the first pic..

                        That's why I used a 5/8 tap on mine and then inserted a 5/8 bolt. Much more thread engagement that way.

                        I don't believe that the factory uses any adhesive, it wouldn't serve any purpose.

                          Get yourself a dremel, a 16oz ball peen hammer and a cold chisel.

                          Use the dremel to cut a slot into one side and then the other of the broken off piece of bushing. Then with the cold chisel hammer then remainder out. It will take about 20 minutes a side with the right bit.

                          Its what I had to do to get it out.

                            A pencil grinder would do wonders, but I ended up using a chisel to chip it away until I could pull the last bit out.

                            Ironically, both bushings came out intact on my iX, which is rusty as hell.

                              insert the lag bolt further. keep at it until the thing pounds out.
