Getting the bushings out was the biggest problem I had. They all went back in relatively easy though. I didn't use a hydraulic press, but I'm sure that would have been easier than using my weight to force them in. Some needed more work than others, but I got them all in just fine. I'm not sure if this is a good idea, but I stuck all my front suspension bushings in the freezer for about an hour or two before I installed them. You will be able to install them either way, but the right tools would definetly help. Just remember to clean all the holes out and put the grease all over. I'm much happier after putting them in and they're worth every penny. Auto-xing sometimes, the tires would seems to lose caster and steering would go numb, but I haven't felt it since.
