Oil leak

To remove a CV joint remove the following;
Wheel
Lower suspension arm, (this will allow you to pull the hub away to be able to remove the axle), So, remove other suspension connections, tension bar, etc. That will keep you from pulling the hub out about a foot or so.
Hopefully you can avoid removing a ball joint by doing so.
Brake caliper and rotor.

Then you should be able to get a screwdriver or small pry bar up behind the axle and pop it out.

Things you will need and/or are recommended to be replaced;
The lock nut for the axle.
Borrow or buy the boot clip crimp pliers as not doing so will lead to a leak if the crimp is not correct.
CV grease, (axle grease that meets specs)
Axle retaining clip.

The othere thing to consider is if the joint needs rebuilding. If it has play in itor has run for a while without grease, it more than likely does.
A re-manufactured axle is generally $100 for a good one and can save you money and headaches in the long run.
You won't need all the smaller parts as they come with nuts, clips and the boots are greased and crimped.

Look around this site and see if there is a link to a reputable supplier near you.

Hope this information helps.
