Nothing too special. Sockets & extensions mostly. You probably should use a puller for the hub. I replaced a front one not too long ago, now the other one is howling at me. Got the lifetime warrantied one from ZZP for $70-something. I set the suspension back down on a pile of 4x4s to keep the control arm straight. Helps a LOT with managing the axle shaft. Keep some penetrating oil and a torch close by as well. Don't forget your fire extinguisher...
