Not being mean. But... It isn't for some one to tackle unless you have access to the proper tools and a bit of knowledge. A spring that is compressed in the strut housing can injure or kill if it releases without the proper tools. If you have any doubt about your abilities and if you don't have the proper tools I would suggest taking it to a mechanic. You can also get a Haynes manual that will take you through it step by step.
