D50 TTB to a solid D50

So if I acquired a D50 out of say an Excursion, could i use the knuckles off my ttb? from the little research I've done they are totally the same for the obvious fact that one's a ttb. The reason I want a D50 vs a D60 is the price, the D60s are going for $1500 in my area. I found a D50 for $400. So the price is right. Before anyone chimes in that the ttb is a good set up let me say I know this, but I want a solid front axle so lets skip the K.I.S.S. discussion. I'm also keeping my eye out for an 8 lug D44 but I'm hoping that I can expand my options. Thanks!

he is talking about a solid axle d44 from the late 70's i believe.

to the op, I have no knowledge of whether or not those parts will interchange. It would probably be heads and tails easier (and cheaper) to just get the excursions rear axle as well and change your wheels.

No, your TTB outers will not fit on the solid D50.

Also, you might want to consider cost of parts between the two. Those D50's can get expensive to rebuild (try around $200 per side for the unit bearing) and the cost of manual locking hubs (another $200). I'd do a little more searching before settling on that D50.

Also the solid axle from a Excursion or 99-01 F250/350 will not bolt in. The spring perches are at different widths, no provision for a trac bar and the steering linkage doesnt fit together

Spring perches are easy to change. Grinder and a welder. And I was talking about the solid d44 out of a 78-79 250 or 350. You don't need a track bar on a leaf spring suspension. It's the knuckles not swapping that kills it. If the knuckles would swap that would eliminate the unit bearings. I'll jet have to find a 3/4 d44. I refuse to pay $1500 for an axle unless it's filled with goodies like an air locker ect. Thanks for thehelp guys!

Oh an glovemeister, a solid d44 is way better than a d50 ttb. The ttb with leafs makes no sense because the traction beams cannot properly move through the "arch" with a leaf spring.

OP, guess what will work (I'm about 99% sure...I know it will on a SD d60)? Knuckles off of a 93-97 f350 front (balljoint d60). Problem is, when (IF) you buy those you can usually score the entire axle assy. Btw, everyone around my area also wants $1,100+ for a d60. I bought an entire 78 for $800 and traded the truck (- front axle) for another complete truck in much better shape, so it was basically free. And I was scrounging around a local yard last summer and bought an entire (disassembled) 93 d60 for $400. The deals are out there, you just might have to work at it a little.

And yes, in the 70's ford didn't use trac bars in the front of f2/350's, but have you ever seen the front of an 85.5-current monobeam truck? They all have trac bars (& for a reason) ...trust me, you don't want to try to get by w/o one.

Driver spring perch is cast into the pumpkin, good luck welding a steel bracket to cast.

An excursion was never offered untill 99 so i dont know how you are calling that a 78-79 axle?

The 78-9 was his alternate choice.

Rebuilding any axle is going to be expensive if you use quality parts...

I can get a complete solid d50 for $400. But I wanna use my knuckles so I can use my bolt pattern wheels and not use the unit bearings on the solid d50. Also I know rebuilding an axle is spendy, that's why I don't want to spend $1500 on the assbembly, then drop that or more on internals. I'm not looking for an axle thatll run 44"+ tires. I'm probably only gonna run 35-37". I mainly just don't like ttb.

Ok, but it won't work for what you want it to do. By the time you go through the axle and replace the bearings/seals/lockouts you'll be around a D60 price. Also, for the tire size you're wanting to run, you can use you TTB D50. I know you don't want to hear it, but if you can't afford to buy the RIGHT stuff, try SAVING. $400 isn't a good deal if all it gets you is a lawn ornament.

So if I get a d50 and rework it its $1500.... But if I get a d60 for $1500 and rework the internals then it's $3000ish..... I don't think your understanding what I'm trying to do.

But what you want will NOT work. You canNOT put TTB D50 Or D60 outers on a D50 Solid axle, so even if the parts were FREE it will NOT work.

And a 8 lug D44 is not going to work in a 80-87 truck either.

keep your eyes pealed for a complete parts truck, they can be had pretty cheap.

Where do you live anyway. you dont have it listed
