Don't forget to put anti-seize or grease on whatever you slide into the receiver. I left my bike rack installed for about a year and had a bear of a time getting it out. I had unbolt the hitch mount from the car, chain it to a tree and wail on it with an 8# sledge while my dad pulled on it with his tractor.

You can be sure I slathered on the anti-seize this time!
