i have a 1973 Jeep4000 camper version looking to upgrade front axel to disk its an 8 lug i would also need to do an upgrade on the instrument cluster
also can some one help me decipher Tag Date: MAR.1973 GWR 8000 GAWR: FRT 3650 REAR 5250 VIN J3A482ZN46945
To upgrade the axles, you have a few options. But none of them will bolt in for a 73. I assume your current truck is 8 lug based off the GVWR, so you just want an open knuckle front with disc brakes.
The most easy axle to find will be a GM D44 HD. It won't bolt in, you will have to weld on spring perches if you want to keep your post mount front springs. You can also opt for a D60 front if you are going to be going with much larger tires and want the extra strength.
thanks, guys I am looking to keep it factory including paint it's going to need some love it has no rust someone added a 2nd tank it all needs to be removed and put back to the original tank I am going to remove the bed and pain the frame
Has anybody tried to fit a closed-knuckle 8-lug Dana 44 with disks? The 5-lug axles have been done a lot, but I don't recall ever hearing of the 8-lug axle conversions. The 5-lug knuckles are all the same for the closed-knuckle axles, but what about disks for the 8-lug hubs?
What do you want to do to the instrument cluster?

I think this isn't done much because Ford and GM switched to open knuckles much earlier than Jeep did. And when they did used closed knuckles, they were drums.
Surprising to me that no one has mounted the Chevy caliper brackets to the drum brake 8-lug knuckles (which I would guess are the same as the 5-lug knuckles) and used an 8-lug disk on the existing 8-lug hubs. Or possibly re-drilled a 5-lug disk to fit on the 8-lug hub. I wonder if it's because no one has tried, or they tried and could not find a combination of parts that works. I would suspect that the caliper brackets are not the problem.
I'm following up on this because it seems like that's what the OP wants to do. And because I'm curious.

I used this guy on off eBay for my closed knuckle d44 5 lug disc conversion. He put a nice kit together with everything I needed. I had to clearance the calipers some but that was it. Might be worth a shot messaging him to see if he could do 8 lug. https://ebay.com/usr/horsepowersales-llc
I contacted horsepower sales back in September his response below
Hi Roger, Sorry we do not have or know of anyone who has a kit for a 3/4 ton 8 lug Jeep.
We have them for 1/2 tons only.
Nice truck! Thanks, Dan
would anyone know where I can get a Jeep j4000 oil pressure adapter plate/fitting I have a leak and would like one in hand just in case i snap off the old one
