Doesn't sound right to me, please confirm

I was *reading* about TTB50s, on Pirate (yeah I know), and someone said TTB44 knuckles, hubs, brakes, etc are the same as 78/79 F150/Bronco stuff.

I'd think the knuckles are different.

If they are the same, then there is a new source of disk brake conversions. But someone else would have figured that out by now.

I don't think they are the same either. Maybe a Dana catalog would show the different part numbers. Next time I'm in a yard I'll do a visual comparison.

If I recall correctly, everything from the spindle out (5 bolt pattern versus the drum/Chevy 6 bolt) is the same, or pretty damn close from 1976 on.

The knuckles are definitely not the same. They don't fit, and the caliper brackets are integrated into the knuckle. I don't know whether the calipers themselves swap. As Zac mentioned, spindle is supposedly the same.

Others have looked into this:

Some parts interchange, which can be helpful to complete an axle someone has partially stripped.

From the above thread:

THINGS THAT WILL SWAP OVER:
gears
rotors
calipers
lockouts

THINGS THAT WILL NOT SWAP OVER:
knuckles
spindles (FSB thread says it is six bolt)
axle shafts

That makes sense. Too bad.

EDITED : The TTB50 knuckles are NOT the same as D50 or D60 solid axles, they have different ball joint spacing & a bunch of camber built into them.

I was hoping I could use my TTB50 knuckles on a 654 front axle, but it looks like I need to find knuckles from a solid D60.

I have a little 1st hand with this. The dana 50 outers are more or less a dana 60 out and 44 inner. There are some similarities to a 50 and 60. The knuckles brakes and spindles are virtually the same as later 97 ish ball joint dana 60 stuff. The spindles will fit a earlier Dana 60 but the index ring is smaller due to the brake bracket being cast in on the later ball joint stuff the earlier Dana 60 has a separate bracket so it needs to index thru the knuckle and the bracket. The later 60 and 50 stuff swaps over fine. The inner is not the same as a anything other than Dana 50 from what I have researched

I recall this being true for the solid dana50 axles which no one wants. Sorry saw ttb 50 after

Thanks, I'm reading a lot, but that involves a bunch of posts that are misleading or wrong all together.

At this point, I just want to use as much stuff as I can from the TTB50. It looks like I can use the hubs, spindles, rotors & calipers (although they will be replaced with new). I hopefully gears, but I'm still not sure. I need knuckles from 92-97 ball joint D60, they will work with the TTB50 spindles. That is info posted by Mr. N, the guy with the D44/D60 info sites, so I'm sure that is good info.

I just edited my post above. Apparently TTB50 knuckles have different ball joint spacing and WILL NOT bolt to D60 inner C's. Either I was confused, or a few people posting on a few threads were confused. Or it was a team effort.

I think they will work

That is one of the threads that got me confused. "Flipped Out" did the conversion with solid axle D50 knuckles, not TTB50 knuckles. He jumps to the conclusion that TTB knuckles are the same as straight axle knuckles. I'm pretty sure he's wrong.

There is a Pirate thread about putting Ford knuckles on a Dodge D60, and it gets confusing too.

TTB50 knuckles won't fit D50/60's, just like TTB44 knuckles won't fit D44s.

I just read this, I think its more reliable:

I'm wondering if they are getting camber and caster confused. Building a ton of either into a knuckle would be a little weird. Caster is almost always on the inner c and how it's oriented on the tube Camber I could see that built in but you can't put in too much. I saw one guy reference the knuckle having toe built in. Lol

Post by **trei75bronco** » Mon Feb 16, 2015 9:36 pm

I would look for a solid axle 50 to be safe .02 I've never been a fan of ttb

Post by **Gunnibronco** » Mon Feb 16, 2015 9:46 pm

I think because of the crazy

TTB design the knuckles had a bunch of camber built in. They won't bolt to a solid axle anyways, so its all irrelevant.

I'm just scavenging parts from the TTB.

I'll be welding D60 inner C's to a HPD44 housing. Then using 92-97 D60 knuckles, brakes, hubs, etc, and D60 axle shafts.

Hows that for a big screwy mess?

I think what they are actually talking about is Steering Axis Inclination, not camber.

I'm sure you are right. And when mated to the correct TTB inner, the camber is fine. When people look at how it would bolt to a D60, it ends up looking like a lot of camber.

I knew I was going down a weird path when I started reading Dodge owner's comments about Ford D60 parts.
