Inspiring technique that I just used to remove my subframe bushings. My advice to others is to make sure that whatever you jam into the subframe, try to find something that fills up all the vertical space so it remains relatively flat when the puller engages. I bent a hefty screwdriver in my first configuration. In the final version I had a piece of bar steel on one side, and the back end of a 2 ft bar clamp in the other. Everyone was the same shape afterwards. Plus the puller drove the bushing more straight down and less to the side. Thank you Andrew.
