What rears do I have?
Hey Red,
There are two places to check. One is the driver's door jamb should have a white tag with codes on it. On the bottom of the tag is the word axle with a code under it. Your owner's manual will decode it. If you don't have a manual post the code here and we'll decipher it for you. There should also be a tag on the rear end housing that gives you the axle ratios.

How do I know if it's a semi float? I'm asking because I got my truck back from the shop yesterday and they did some work on my rear and the tech said it was a full floater. Which is better, semi or full floater?

A full-floating rear axle is theoretically stronger & safer because it only receives the torque of the driveline. A semi-floating axle gets that load AND the weight of the truck on each rear wheel. If a full floater breaks, that axle is dead, but you can lock in 4WD and drive home in front-wheel drive. If a semi breaks, the wheel comes off.
FFs are easy to ID by the small ring of bolts on the outermost end of the rear hubs. These bolts connect the axleshaft to the hub, and by removing only them, the axleshaft can be slipped out of the axle housing with the wheel still on the ground.
All live (4WD/AWD/FWD) front axles are FF.

Thanks for the info 84f150. I thought that my truck had 4:10's out back, because it revs pretty high going down the road. Also is that a strong rear? I have heard that the Dana 40's aren't the toughest so is mine any thougher?
