2002 owner looking to convert to 4x4

Hey guys I have a 02 xe 4x2 and I was wondering what was the most cost effective way to convert to 4x4. I dont care if it requires taking salvage parts but if someone could give me a list of what I need and a price estimate I would love that thanks.

Pretty much for free. You can buy this one:

And from the prices I have seen, sell yours for the same or more.

Do what I did:

1. Take your 4x2 truck...



2. Add full-coverage insurance and a distracted teenage driver...



3. ...and voila! A 4x4 for only $30 a month more in insurance premiums.
