I’m doing the front brakes on my 78 Ramcharger. Of course it is still constant hubs and these are likely the factory rotors. I got going not realizing how they remove! Yup, not just your average pull em off and stuff em on job. No, you need a tool to remove the assembly from the axle and then the hub and bearing press out of the rotor. Who does this stuff! :) Anyway, I built myself a puller. Of course my tolerances were way too tight and I had to hog out the holes! Oh well, it worked. I do love creating this type of thing. But I also love easy jobs!

glad you got them off. i have 2 factory removers for them and was going to list them in tools for sale but did not get around to it. so sorry on my end. the tool also fits 3/4 ton. again sorry. rick w.
 
also when you go back together, you may want to remove the 6 bolts as there is a seal behind the bearing that is still on the rotor. the hole in the rotor allows for socket to get in and remove the retainer. don't remember for sure but bolt heads are either 3/8 or 9/16 socket 12 point head.
 
They were actually on there pretty tight! You bet. I plan on removing to get at the inner seal as well. I think you are right with the 3/8, but they are 12 point according to what I have now read. I believe you can grease the wheel bearings and or remove the entire assembly by working through that hole. The grease zerk is at the upper left in my pic. Tomorrow's tasks!
 
That looks like a modified version of those stupid front wheel bearings. I hated them from the day they came out (on Dodge full time 4x4s) and now everybody uses a version of that mess
 
I've done a few of those. Totally archaic design for sure, BUT it's heavy duty as hell and WORKS.
 
I made that same puller for my '77 Ramcharger back in the mid '80s to replace the bearing set and do the brakes.

Ya, that is NOT a 1 hour job!

Lol, my right side took me two days!
I had a "reliable" local outfit turn the rotor, and it pulsated the pedal once back together. Tore it back down and they made another skin cut to .020" or so above limit, but it had the exact same pulse issue when reinstalled. I didn't take it back there a third time.
Took it to work and a toolmaker chucked it off the outer hub and indicated it in. He found a counter sink that the brake lathe was centering on was way out on one side. So he turned it for me on the shop lathe and it worked fine on the reinstall.
