I'd say it's a weekend job if you have all the parts, nothing goes wrong and you've got a press and some air tools. Otherwise... plan on your 5 day thingy.
When you say remove hub do you mean you'll be replacing your bearings as well? You don't need to remove the hub to get the bushings off.
Bushings come out best with a press. I heat the rod end that I'll initially be pressing with a MAPP torch. It helps break the bond it has on the bushing. Press it through and remove the bushing with a large screwdriver. Turn the control arm over and press the rod back the other way. Same torch method. Same screwdriver. Best to cut grease grooves in the new bushings and lube with your favorite synthetic grease. If you don't have a press you can probably use the torch to burn the bushings out. It's worth the $99.00 Harbor Freight investment to get the press (IMHO).
If you'll be removing the hub and the bearings it's best to use a drift on the hub. I use an old 911 torsion bar with the fat end. One whack with the sledge and they're outta there. Next the bearing has to come out. I use a blunt ended chisel on an air hammer. If they don't move after a couple of short bursts then I apply heat with the MAPP torch again. That usually breaks the bond.
Good luck. Let me know if you have any questions while digging in...
