Replace steering box

Replace steering box
Dang, I hate doing this job again but it's time. Any suggestions on getting it out without breaking my back? It came out the top last time. Maybe I'll take off the hood and get some help.
Looking to use a Red Head ( I think is the company) replacement possibly with a tighter steering ratio.
Any thoughts on just replacing the lower seal and bearing in place.
Thanx

I would use a cherry picker? Or get a buddy, a piece of pipe, tie a piece of rope to the box and with the pipe on each of your shoulders, roll the pipe lift the box then walk it out, like carrying a deer.
Or as far as both seals, so I have read....It’s done before with the box on the bench, but I think it can be done on vehicle? Out put seal..remove the pitman arm (gear puller if better than a pickle fork) from the steering box output shaft (sector shaft), then there's a snap ring that needs to be removed.
Once that's out of the way there is a washer, then a seal, then another washer and another seal. Remove the first washer exposing the first seal. Take a sharp center punch and pierce the seal, screw in a sheet metal screw and pry the seal out. You can do two screws 180 degrees apart too.
Once the first seal is out, remove the second washer and repeat the process. You can also try just removing the snap ring, after the pitman arm is off) turn the wheel to the left and start the engine, it will usually blow the whole thing out, both seals and spacers but you better have a huge drain tray under it, then reassemble.
To replace the seals, apply a thin coating of grease to the inner lip of the seal and a thin coat of sealer to the outside diameter of the seal (I like No. 2 Permatex non-hardening). Slide the seal over the shaft and take a deep socket that’s just slightly smaller than the OD of the seal and drive the seal in until it seats. Replace the washer then the next seal, washer, then the snap ring.
Reinstall the pitman arm, hook up the steering linkage and that's it. If you don't have a socket that's deep enough you can use a piece of pipe or tubing too. The killer on these is getting everything centered. With the exception of the sector shaft Ford basically only sold the internals as an assembly.
