I have a front D44 from a waggoner & I want to get some Chevy flat top knucles for HI-steer set up. I have found a Chevy 3/4 ton 8 lug D44 housing for sale. Are these the same flat top knuckles as the 1/2 version? Will the 3/4 ton 8 lug Chevy D44 knuckles work on the waggy axle? If the knuckles fit I would like to use all the chevy stuff(rotors,hubs,calipers,ect...) is this possible? Thanks

PS> I tried "searching" didn`t get a good answer:flipoff2:

All I can say for sure is I have used flat top nuckles off an 8 lug axle for 6 lug crossover, fit perfectly. The nuckles are exactally the same 8lug or 6lug as far as I know.:D

I can't believe the search didn't answer this, but it does get clogged up with flame fests and the real tech gets lost in the mix.

Yes, Chevy and Jeep 8-lug and 6-lug knuckles are the same, and the eight lug stuff will bolt up to your Jeep axle, no problem, or you can stay with your 6-lug and just use the Chevy knuckles.

The difference between the knuckles is in the way the spindle bolts up the waggy, knuckle studs are clocked differently but if you are going to use all chevy stuff, knuckles and everything --no prob.

Thanks... I know it was a simple question that has probly been asked hundreds of times but I just wasn`t sure if it would work.
Thanks guys

There will probably be some difference in the height at which the stock tie-rod attaches to the arm on the knuckle. It's higher on the Jeep, in order to raise the tie-rod over the springs in its factory SUA setup. It's lower on the Chevy, to keep the tie-rod clear under the springs in the Chevy's SOA setup. This will only be an issue if you are keeping the axle SUA and trying to use the stock tie-rod along with the high-steer drag-link.

Jeep and GM are the same, Ford uses different bolt count (5 and 6 bolt) and clocking.

GM and Jeep were almost always "toploader" type knuckles. Dodge and Ford like to have the tie rod coming in from the bottom of the knuckle.

What are the chances of putting a chev 44 long side shaft and stub into a 79 ford hp44? I just picked up both and the chev has a craked housing and the ford has nothing from the knuckle out on the long side. So my plan might be(if it will work) to put every thing from the knuckles out from the chev onto the ford. I was too tired tonight to go at it but some rough very rough measurments show that the chev might be about 1.5 longer.

Right. I thought I saw a set of comparison pictures on a Dodge site that showed the difference between the height at which the tie-rod end dropped into the steering arm, but the closest I could could come up with was this page comparing the Scout knuckle:

I got this link from the following page; good resource, even for us non-Bronco folks-

Thankx for the info
Im not using stock tie rods or drag link, also It will be SOA with waggy 44044 springs. Im going to fab up my own heim jointed tie rod & drag link. Im still not sure which pittman arm I will be using yet.

Chevy knuckles out will be fine on the Ford, but you'll have to find a Ford long side shaft, or cut-down the Chevy one.

The Chevy axles will be 36.13" for the long, 18.31" for the short. If the Ford axle is coild sprung the long side will be 33.91", and the short side will be 18.91". If the Ford axle is leaf sprung the long will be 34.75" and the short will be 18.625"

Where are you getting you 18.31 for teh Chevy? :confused:
I'd bet it's 18.5" (has to have 5-297x u-joints)

Also on the Ford Reverse Spiral info, it depends on the axle as Ford ran a LOT of different axle shaf lengths! Check my Dana 44 artilce and click on the Dana 44 axle shaft length link. I list all of Ford's axle shaft from 67-80. :idea:

O Yeah, no the Chevy long side will not work, have you been to my Dana 44 page?

From the Warn "It's been wrong so many times it's not even funny" axle chart....I've been meaning to verify some of the Chevy facts but my parts pile is 250 miles away covered in snow. I do know that the Chevy short side is a straight up swap for an Early Bronco short side, and a cheap upgrade to 297 joints, and you list the EB short shaft as 18.3125" on your chart (which I feel no need to verify, you've done an excellent job and I'd tend to believe your numbers over a tape measure and part in my own hand)

I'm working on a Dana 44 user's guide with housing dimensions, axle shaft specs, knuckle dimensions, etc. When I've verified all my numbers you'll be one of the first people that gets a copy to review and mark up.

Do you have Dodge and IH specs like the Ford and Jeep ones on your site?

This is 100%, without a doubt, True. I just had my EB and cheby short axles laying next to each other a few weeks ago. EXACTLY the same length! The fs ford short axles are a tad longer.

Yep, in the X510-8 DSD book (from 67-78). Before 1967 it's hard to find info from Dana. Also after 78 (80 for Ford) it's hard to find detailed info (searching the web page is OK at best). I've collect some books, but still think i need a Job for a couple weeks at Dana to see more :p

It's not EXACTLY the same length. From my Dana article --> "Note for the Early Bronco's, It's a common swap to use an F150 short side shaft to replace the EB shaft. This is to increase the u-joint from a 260 to a 297. While reading the chart you'll notice the EB shaft is 18 5/16" and the F150 shaft is 18 5/8 to 29/32" in length. Thus it's common for the F150 shaft to be trimmed to fit on the pumpkin side. However the Chevy Dana 44 shaft is 18 1/2" so it would work much better as an inner shaft than the F150. Also a Dodge W100 from 1972.5 - 74 with B.O.M. 603413 has the exact same length axle shaft but with a 297 u-joint! (I'm not sure on the grove in the spline, yet)"

I knew I should have taken a picture :shaking: :flipoff2:

Thanx boys I diving into it Sat. Keep it coming.

Get the pic!

A big thanks to you Mr N. for all the useful info on you web page:http//77cj.littlekeylime.com/web_rs44.html I haven`t found this much info on dana axles anywhere else.
Thanks again:flipoff2:
