Trailing arm bushings

[ryans69chevy]

I can't seem to get these out. First I tried using a hammer then I drilled out the rubber and got the inner sleeve with rubber out, but couldn't get the outer sleeve out so I took a saw zal and cut it in half which I now think was a bad idea... With the other trailing arm I went and rented a ball joint press and could only get the inner sleeve 3/4 out cuz it would hit part of the clamp.

I've read on here that people use these all the time. So what am I doing wrong??... I know I could just take these into a shop and pay to get them replaced, but I enjoy doing this stuff on my own and figuring it out, but I can't seem to figure this out!

Thanks,
Ryan
