I can't find a repair manual for 2009...  I assume the 2008 manual is still plenty current, but to be safe I decided to run it past you experts before I go ahead and buy it.  Also... is the Haynes manual below the best out there for my 2009 F or is there any other options for 2009's I should consider?

thanks in advance

The only change from 2008 to 2009 is the rear axle nuts.  The 2008 manual will do fine.

I always like to have the factory service manual also.

Thanks alot man...I figured they would be pretty close...  I am itching to do some tinkering, so I'll be ordering the manual asap.
