dodge flatop knuckle

Trying to see if a early 80's dodge pass side flatop knuckle can be used for crossover steering on a 83 J10?If not what vehicles can they be found in?

I dont know much about nothing, but I have a set of 76 dodge flattops in my garage and I can tell you for sure that they are not the same as FSJ knuckles....meaning that the stuff off the FSJ won't work on the Dodge knuckle, so you need to get all the dodge stuff to make it work. The prob with that is that the Dodge setup is so dad-gum moronic that you would have to be half crazy to install it on oyur rig. It has been a while since I pulled the axle apart, but it was an exercise in patience as the design is just absolute crap. It took forever and I was making oaths against ever owning a dodge halfway through that hellish job.
Not sure if your are the same though, and yemv
Here's the ones I am talking about:









If you've ever seen an FSJ knuckle, you'll immediately note some big differences....but like I said...these are from a 76, so take all my rant with a grain or two of salt.

flatties

There were differences in the Dana44 fronts that Dodge used in its half and 3/4 ton trucks when they changed from the small,pathetic, oddball 5 on 4.5" unit-bearing live-spindle (hubless) design used on the full-time 4x4 models from '74-79 ......to the 5 on 5.5" 'normal' Dana44 fronts with the more commonly known Dana44 bearings and knuckles used in the '80-93 front axles.

Find an 80-93 Ramcharger or a 1/2 or 3/4 ton pickup Dana44 front and pirate the knuckles off of it.

The pre-80 Dodge Dana44's are absolute junk

You can find the 'good' flattop knuckles on any
'72-77/78 Chevy/GMC Blazer/pickup Dana44 front axle
'73-ish-76/77-ish FSJ Wagoneer/Cherokee/J-truck Dana44 front
or the fore-mentioned Dodge axles

I have a friend that has a couple of early 70's Chevy Blazer Dana44 fronts with the flattop knuckles here in Texas if you want one. I bought a pair of pre-machined flattops off of a guy that bought them on ebay, so you might wanna check there.

flattops pop up all the time on CK5.com

Great tech wicked wagon. Glad to hear Dodge firgured out how to make these things after 79. Absolute junk is an understatement.

well, yes, if you are talking about a unit-bearing dodge, then the knuckles are a no-go. but i thought the question was about a mid-80's dodge, which should be the 'normal' spindle and caliper mount style stuff.... of course, if you REALLY wanted to use the unit-bearing stuff, you could, you would just have to use the dodge caliper, or take a stock car rear caliper bracket for a GM big caliper, and modify it to bolt onto the dodge knuckle...

a lot of people bag on the unit bearing dodge front ends, but they still use the same basic design and even some of the same bearings on the new one-tons, all those 1500, 2500, and 3500 dodges of the new body style run that same system.

perfect? no. useable? yes.

peace
Dave

no. An 82 or 83 Dodge factory Dana44 front axle will not have the weak unit-bearing design. As long as you know for certain that the truck is an '80 or newer

you're good to go

actually, the 80-84 Dodge front Dana44's are the only years dodge/dana spicer didn't mess up the axle as a whole. The '85-'01 factory dana44 fronts all had the troublesome CAD ( central axle disconnect ) vacuum operated housing. If you can get the whole axle assembly off of an '80-84 from a wrecking yard you might be able to gain some coin selling it without the knuckles, as they're getting difficult to find for those that are looking for them.

Some Dodge fanatics look to keep a Dana44 front under their '85-93 Ramchargers/pickups but replace the CAD housing and tubes with an '80-84 unit.

Anyway,
good luck man

They will work. You'll have to use the Dodge brakes. They also use smaller TRE's than the big Jeeps, so you'll have to ream out the steering arms to accept the bigger TRE's. I have an '85 Dodge D44 swapped into my J2000.

are you trying to just swap in dodge knuckels on the jeep axel or are wanting to spring over and cross over by swaping in the whole dodge axle?

here is what i did when i swaped in the whole dodge axle for my springover and crossover. the steering arm is just a 1x2 bar with a 1x2 spacer under it I did not machine the knuckle just filed it pretty smooth. I used the stock draglink (j-10) then extended it by screwing in the hiem joint at the end you can see all the details in the pics

The search has ended for me.I found a flattop from a cherokee yesterday.I do think the dodges will work as long as they are from the correct year.But knowing that the cherokee would work is what made me go that way.
