a 44 will live OK with 38s if you are not stupid. Expect accelerated wear on your balljoints, and steering. Maintenance is the key, along with good driving skills. If mud is all you do, a 44 is ok.

Unless it's a crewcab or crewcab front axle it's a d44 that said there were two different d44's available for the f250 in 75 one rated at 3000 lbs gawr and one rated at 3550 lbs gawr they both had drum brakes and are the closed knuckle design the 3000 lbs axle had small tapered hubs like a f150 the 3550 lbs axle had the large non-tapered spicer hub but like was said beford for mud and normal trail rides a d44 is ok for places where wheel spin to solid hookup is possible or the possibility of "catching air" you'll want a d60 high pinion from a 78-79 or later I have d44hds in both of my highboys and have run 14.5 x 36.5s and 12.5 x 35s without any trouble but they don't see any really hard use anymore.

It will mostly be mud and sand, it should be fine if im easy on it, eventually i would like to upgrade to the d60 with discs on the front, but thats when money lets me 
also, with a 6" suspension lift do i need to lengthen drive shafts, or is that an issue? i think i am going to run 37"s instead of 38"s
