There is a special tool to remove the bushings. It costs about $110 to $130 depending on where you buy it, but Performance has it. I just did the rear end bushings on my 300E about three weeks ago (Front and Rear). The bushing are very inexpensive from the parts shop on this site. I started the job and realized that it was more involved than what I was comfortable with. I took it to my mechanic and it cost $237.00. I did not buy the special tool, he used an air hammer instead. Everything worked out great and the differece is tremendous!
