i have just finished replacing the rear bushes...my god, they were SO easy. took about 1 hour to get the axle of then about 10 minutes to get the old one out by drilling out and hitting it out. i made a tool myself to press the new one in..hey presto that took about 10 minutes too

whole thing took no less that 2 hours from stop to Finnish...hardest part was connecting all the hoses back up, took about 2 hours to do that on its own!
I thought it would take ages and be really hard to do...ill put the photos up of the tool i made

If anyone is thinking of doing this let me know and ill let you know how to make the tool
