Default Dana 44 knuckle brake question

OK, so I have a scout dana 44 axle. I had Dana 30 knuckles on it with the original dana 30 brake calipers and caliper mounting brackets. The bracket mounted onto the knuckle with two bolt holes.

Well, I just got 2 new Dana 44 flat top knuckles off of a chevy (the 6 bolt ones) and am putting them on the scout axle. How do I mount brake calipers on these? They do not have the same 2 holes to mount the brackets to.

Is there a special bracket for the chevies, or do I need to fab something up?

Yeah, don't think too hard.


And don't mention to the guy at the parts store that you are working on a Jeep. You are working on whatever year Chevy pickup or Blazer the knuckles came from. For all practical purposes, you don't even own a Jeep.

Do the chevy calipers mount straight to the knuckle then with that one hole? Or is there a bracket that holds the caliper that i need to get? I guess im asking, how is it that the chevy calipers mount to the knuckles?

Thanks for the responses!

You need the chevy calliper bracket, like what monkeyevil posted. I run this set up. It's the chevy small diameter spindle, with the chevy backing plate, with the chevy calliper, with a ford f-150 hub and rotor. That will keep your pattern 5x5 1/2.

There is a good tech article on POR for biulding a hybrid 44, talks about this conversion.

That bracket simply uses the same 6 bolts that hold your spindle on now. Leaves the spindle on, just pull out the bolts, slide the bracket on and install the 6 bolts. Go to Autozone, spend $30 on calipers and slide pins and your good to go.
If you want to keep the same size brake line banjos, the Waggy calipers use a smaller banjo bot than their chevy counterparts.

Ignore the D30 part, but the rest is exactly what you all need to know.

I don't mean to hijack the thread, but I'm having a little trouble with this myself. Last year I ran stock later waggy knuckles, with spindles that had been turned down to Ford bearing sizes and it worked ok.

Now I'm doing Hi-steer and got some knuckles, spindles, and stub shafts supposedly from an early FSJ-(I'm thinking that it's true, as neither of the flat-top knuckles was drilled.) Anyway, The spindles are small bearing, (the bearings fit on the spindle)

The trouble I have is with the inner bearing seated and the hub installed, the outer bearing hits the end of its journal on the spindle by at least 1/4".

Basically the bearing won't fit all the way into the hub because it hits on the spindle.

Did the waggy use a different "small bearing" than the Chebby? I've read for a while that they were ok to use too, but apparently I've got the wrong ones.

Thanks for the help.

Phill

It depends what hub/rotor assy you are using? What lug pattern do you want to use?

I'm using 5 on 5.5, it's a F150 rotor from the Junkyard, I'm guessing late 70's early 80's. Were they not all the same until abot 88-89 when they did one piece deals for a while?

It should work. Take a close look at your spindles, and look at this picture taken from this web page http://www.partsmikeparts.com/spindles.htm



This shows the difference between the later and earlier spindles. It sounds like you have the later spindles (the one all the way to the right in the pic).

If you have spindles that are turned down for the small bearing style, use those. Or look closely to see what is different between the ones that worked for you and hte ones that arent.

Hey Shawn,
I appreciate your help . . .

I have the small bearing spindle. (I also have a set of large bearing ones)
I The issue is not with the inner wheel bearing, it's with the outer one. It just won't go on far enough to tighten it hits the next diameter step beofre it seats in the race. . . .

I don't have time to investigate now, I'm gone from home from now till sunday night, but I'll have to look at rotor/hub/bearing part numbers.

Thanks again.
Phil
