Start soaking all connection points now. Get under there and spray loads of PB blaster on every nut, bolt and potentially siezed orifice.

Walrus covered the good points. The long bolt that holds the lower A arm in is always what gets me. Sometimes they come out easy, sometimes you have to hammer like a madman for hours to get it free.

There is a tool you can rent from autozone called a 'ball joint press'. They charge you $99, give you $99 when you bring it back. You can do it with the picklefork but this will make it a little smoother.

The upside of this tool is that it can be used with a decent assortment of large sockets as pushers and receivers for pressing the bushings in and out of your suspension bits. Real lifesaver on my carport.
