How do i replace the coil springs on a 2006 honda

Front are McPherson strut and you need highly specialised tools to change,plus they're under compression and if you are not experienced DON'T try to service them.Any brake-shock shop will change them out quickly and safely.The rear ones can be easily replaced with a floor jack and some common hand tools.Block the front tires(front and back of tire),jack car on the jack pad in front of the tire your going to change the spring.Remove the bottom shock bolt,this will allow the control arm to drop enough to pull out your old spring.Some times you need to unhook the sway bar to get added clearance.Replace the new spring making note of the original springs orientation.
