EB Drum Brake 44 to disc

I got the majority of the information I need to convert a D44 to High Steer using Chevy Flat top knuckles. My question lies here.

Can I take an EB drum brake D44 (which is close to the width I need for a stock YJ) and convert it from the smaller u-joint to the larger u-joints (the numbers escape me as I write this. But basically the smaller D30 size and the true 44 size). I looked today, and it seems to me that the ball joints may/will interfere.

What say those with the knowledge (and perhaps I should have posted this in the Ford section...?)

should work. just the same as the D30 can accept the larger 297/760 u-joint in place of the smaller 260 joint. balljoint in the way? i guess that's possible because the ears are a bit larger to receive the larger diameter cap.

So, what axle shaft goes in there to make that possible? I hate to make custom shafts out of full size long side shafts, or whatever else will work....

I have limited EB axle shafts at my shop, and they are both (yes, I have two sets of shafts) the small u-joint size.

i don't know if there are any stock shafts available with 297/760 joints that you can throw in there. this thread has some similar questions:

Thanks, I will read that tonight when I get home.

My plan is to trim what I need to in order to fit the bigger u-joints, chevy flat tops, caliper bracket, and spindle then ford hubs, calipers (or chevy calipers, whatever fits) from a 70's ford half-ton. Sky Mfg steering arms should complete it. 5.38 and ARB would be the final setup for the diff.

Shafts I will probably have to send to Dutchman and have them narrowed. Guess while I am at it, better send two sets for spares.

Ball Joints

I believe that the early bronco ball joints are a different size and do not accept the chevy flat top knuckles. (when converting from disc brake).

Some one chime in if I am wrong.

Then your going to have to find another axle.

ALL Dana 44 front axle shaft from 1967-2005 --> http://77cj.littlekeylime.com/Spicer...afts_Mr.N_.gif
Nothing is the same length as the EB shaft, You'll need custom.


You can swap those Chevy knuckles on you EB Dana 44, and the u-joint will fit no problem.

If you are using the chevy knuckles you need to use chevy spindles, ford disc brake spindles are 5 bolt, chevy are 6 bolt. To use ford rotors on the chevy spindles you need the small bearing chevy spindle. Use the chevy brakes. I believe the chevy outer axle will be the right length and have the bigger joint, Bronco graveyard has some replacement axles for the early broncos that take the bigger u-joint, might be as cheap as shipping and resplining.

Brewchief, after re-reading my post, I saw the confusion. I meant that I would use the knuckles, caliper bracket, and spindle from chevy, then ford everything else.

I will check out bronco graveyard also. Might chick into Toms Bronco Parts.
