Well, I guess rust plays a part but not through weakening the stressed member but by adding wiggle room.
I do have a spare unit but its a couple years older, everything looks the same but the brake calipers are different as are the mount on the knuckle, but the ball joints look the same as do the hubs and the spindle itself.
I think my spare unit is from an 86 but definately want to do some closer comparisons.

Have a question, I'm guessing that this is a Dana 50 IFS as it has the big lockout hubs on both the truck and the spare axle. I have seen a few with the big "50" cast into the housing, neither of mine have that.

An easy way to tell a 50 is the u-joints have external snap rings, the 44 u-joints are smaller & have internal rings.
Never seen a 50 without it cast in the pumpkin.

Hmm, well all my snap rings are external and the lock hub is the same size as the rotor hub. It is the 4600lb axle code 26. 3.55 ratio from the looks of it, seems to match the description of a D50 ifs.

My mistake then, I thought the hub looked necked down in the pic. It must be a 50 center section as well, because I can tell you from experience that you can't get the snap ring in if putting a 50 shaft in a 44 housing, I tried to use a 44 center section rather than changing the ring & pinion on a 50, but couldn't do it.

I guess its odd to me, most '50's I've seen have the cast 50 on the housing, but I have two that don't, maybe that was for another date range. Hub might look small with the excavator tooth shoving it downwards

Good deal Dan, yeah, mine ran for 80-100 miles with the cracked housing, tons of load on the inner axle bearing, lock hub and spindle bearing. I've replaced the lock hub and spindle bearing but the diff oil was glittery, drat!! slap a magnet on the fill plug and run it, first day came off with a wad of metallic grease the size of a large grape. Soon as the snow is gone I'll see about swapping it off. No chips yet, just powder but all bad.

mine snapped the mid-shaft at the splines too - I was trying to yank a snow plow out of a snow bank. I replaced the whole mess with a D60 and detroit tru-track and never had another problem other than a slightly rougher ride. Need a used 411 D50? All or parts -CHEAP!
Also broke the mid-mount and replaced it with a Trailmaster lift mount which was stout enough to finally break the bolts right out of the cross member leaving big star shaped holes in it. Nice quality stuff..............

Sounds like a hard day there Alta, after adding another leaf to the front and getting my springs re-arched, I had a lot of torque on those inboard mounts and the camber was way off. I reinforced the oem brackets and extended them down 2 inches, moving the bolt down to get the camber spot on and put things in a neutral axis with the spring perches.
I did pick up a dozen rare earth magnets that were 5/8 x 1/4 inch, a little lathe work on all the fill plugs on the fleet and now everything has magnetic fill plugs. nuff magnets to do the drain plugs too.
