Crazy alignment problems
Correct, I have a piece of pipe that is the same size as the bushing lip to press them in the arm, I also put a little gear oil on the outside of the bushing (metal part only) don't get it on the rubber, it will press into the arm a lot easier.
You can run a bead of weld down the inside of the old bushing and when it cools it will shrink the bushing and it will come out easier. Just don't burn through it.
