If I was to pull an OEM factory hitch off a junked E53 2006 3.0 or 4.4:
-Exactly what all tools will I need?
-What are ALL the parts I should grab?
-Basic instructions on removing it?
-Is it a one man job?
-Can I do it without a lift and on the ground?
-What are some challenges I might encounter ie frozen (rusted) bolts? I do have an impact wrench.

I know it's asking a lot above for details but I'll be driving a couple hours and don't want to not have all the tools I need. I did research but not finding complete info.
