A true alignment from someone that knows what is required for a TTB should be done. I suggest you take to a Ford service center.
That being said, you can get very close on your own if you have a level surface and the proper tools.
You may need to buy new alignment cams and install them.
First, go buy some Kroil or Liquid wrench and spray the nut on top of the upper ball joint and both ends of it's pinch bolt. Then do it again, and again when you start your alignment.
You will need a 12mm, 12 point socket (1/2" driver preferred)
1 1/8" deep well 1/2" drive and (2 maybe 3) 6" extensions
I used a 15mm on the tie rods, I think that's a 5/8.
2 steel plates per wheel (4 total) with grease in between them. You can also use 2 magazines per wheel.
2 bubble levels that will fit level on your wheel. The smaller the bubble the more accurate.
2 4-5' copper pipe, or straight rods or something long, light and straight.
Drive over your slip plates. Do not use a jack. Set the parking brake and chock a real wheel. Inflate your tires. Use zip ties and mount the bubble level flat to your wheel so it is perpendicular to the truck. (pointing away)
Loosen the tie rod bolts, and upper ball joint pinch bolt. It is best if you make opposing alignment marks on the cam. This is so you disturb your caster as little as possible. Using the big deep well socket and extensions, turn the cam one way or the other until the bubble level is just on the outside of level (if possible). Don't turn one alignment mark past the other and your caster should stay put. Tighten the pinch bolt and recheck level.
Now take off your levels and zip tie your pipe flush to your wheels so they extend forward of the tires. Make a mark on the end, and as far back as possible on each pipe. Measure these two points and write them down. For the best handling you will want the tow in just a hair. So the farthest point away from the tires will have a very slightly shorter measurement than the nearer point. You will turn the tie rod sleeve the same number of turns each side (unless your steering wheel is off center). When your ever so slightly toe-ed in, tighten the sleeve pinch bolts and recheck.
Go for a test drive. Take it easy at first to make sure it doesn't pull or do anything funny. I would check everything again after a drive. It will change. I did mine on a dealership rack three times in a row. It does change after a drive and you will want to set it back.
Now your done, have a beer and pat on the back.
