When I did this job, I managed to get the tool on the bushing a little crooked. When I tightened the bolt, the tool bent the outer shell of the bushing outward a little, sort of mushroomed it. No amount of tightening on th bolt would move the bushing. I had to take a punch and hammer the mushroomed part back in before I could get the bushing to move. When I did the second bushing, I was very careful to get the tool centered on the bushing and then the bushing came out much better. PBlaster was also a great help. Lube the tool threads each time you use it.
