I love my polyurethane. But they aren't for everyone and they don't last forever. Life is actually shorter than stock,
What? Shorter than stock? That's goofy. That outright shouldn't be happening. Did you forget to grease the bores before installing the inserts?
the ride is much better IMHO. Some people like mush...different bores and strokes for different folks. In a cab, some people would claim the car's ride was 'harsh'.
You can design the bushing for different characteristics. Right now all the offerings are solid bushings designed as ultra-durable replacements for the OE bushing, but if you design the car to use poly bushes from the beginning, you can design as much squish into them as you like.
Bushings are a bitch of a job, even with a hydraulic press. You'll need some steel stock, a band saw and welder to make a custom drift before you are done.
I use a miter saw with a grinding wheel to chop metal stock. It has kind of a wide kerf but it's not really a practical problem. You can use sockets to push poly bushings (they come in a variety of sizes and have a nice rounded edge which won't chew the bushing) and I have a pretty comprehensive set all the way from the itsy bitsy ones up through 3/4" so that provides for installation of most bushings. I also have the HF 4x4 ball joint kit, which can be used in a pinch, if clamped into a vise. My vise is mounted on a pedestal made from a Chevy astro axle shaft and brake drum. And I do have a hydraulic press. The only poly bushes I ever pressed in, though, were big ones from whiteline for the radius rod on the 240SX S13 front suspension. Maybe those were easy.
