hd44 axle disc brake conversion

Post by mybros71 »

I've searched on here and been unable to locate a source of information on changing my front closed knuckle Dana 44HD axle over to disc brakes. It's on a 71 F-250 4wd. 3500#axle with factory drum brakes.

Supposedly it's possible with chevy spindles-out, but your miles ahead to swap in a complete 76-79 axle.

I think that's what we're going to end up doing. I just happened to have an open knuckle, 8 lug, Dana 44 with two flat top knuckles. It's out of an early Chevrolet. I wonder if the knuckles will bolt up to a high-pinion FS Bronco housing? I have one of those too. I don't like the thought of down grading the axle weight rating, but I want to have discs up front. Thanks for the info.

Not sure wether the chevy knuckles will work. The bronco axle needs coil springs and radius arms, your F250 4x4 has leaf springs

I intend on adding the perches for the leaf springs. The axles are both Dana 44s and should have the same ball joint locations. I don't know. It seems like the later model axle is the way to go though. Now to find one some joker hasn't bought up to put under his pavement pounding Silverado.

The DS perch will be right on top of the diff housing. That's why the perch is cast into all the leaf sprung axles.

Adding a perch to the housing is not that difficult. If I can scrounge a later model complete axle, that'd be much less challenging. The problem is, I'm a tight wad and have most of the stuff to use the highpinion. I am going to spend some time to try to find the later model axle so there's less fabrication. If I can't find it or the price isn't right, I'll get to modifyin'. Thanks for the input though. I really appreciate it.

Thanks Garbz. I knew I had heard of such a place, I just couldn't find it.
