HP D44 question

My Jeep has HP D44 axle in front, Ford 9" in the rear from a 1977 ford F150, the rotors on the D44 are warped and can not be resurfaced so I went to the auto store and bought just the rotors, tore the hub apart to find out its one damn piece. Any way, I got the rotor and hub assembly, but I have forgotten one thing and I dont remember. . .

My question is, once I have the old assembly out, will the inner bearing be easy to take out and reinstall on the new rotor/hub assembly or will I have to press it in?

If I do have to press it in how hard is that to do, or is there an easy way to do it?

Any help is appreciated!!!!!!!!!!

Thank you

mine is a '78 axle so I might be talking out of my arse here:rolleyes: but if you press the wheelstuds out you should be able to separate the rotor and hub
if not, then pressing the races out/in should be fairly easy with a punch/hammer. If you're carefull you might be able to reuse the inner seal as well:smokin:

Yea, I tried to knock out the studs but no go, it looked like it was 2 pieces but it is totally one piece. I bought new seals so no worries there, but what i'm most concerned about is the bearing, the outer bearing is easy enough its the inner bearing i'm concerned about since I didn't try to remove it initally after I found out I need the entire housing.

You should be able to drive in the new race pretty easy. Get a bearing race driver set and a deadblow hammer and you should be good to go. Just take some time to ensure it's going in straight and you shouldn't have any trouble.

I think some of the chalie cheepo chineeze knock offs are one piece or assembled as one piece. The originals are a 2 piece assembly, hub held to rotor by wheel studs like frwinks said.

A 77 F-150 will have the two piece hub/rotor held together by the wheel studs unless it is aftermarket as stated by 4XFORD. I replaced the bearings on my axle and just used an old race and hammer to install the new race. I turned the outside of the old race down with a grinder so it wouldn't get stuck after installing the new race. Just work your way around the race as you tap it in so it goes in straight.

Should I be replacing the bearings as well? I hadn't planned on it, they are fine, however I dont have an old bearing to use to help me press them in. What are your thoughts, replace the wheel bearings as well?

The inner bearing will fall out when you pry off the old seal. Then use a long brass punch from the outside to tap out the inner race. Do the outer race the same way. Clean them check for wear and heat checking, if they are ok grease them, and put it all back togeter. After cleaning the hub out install the race's by gently tapping them back in with the brass punch or brass hammer. Make sure they go in straight an not one side of the race before the other.

they are two pieces, have you tried banging the old studs out? You will need to bang them out (use a nut on them so the thread stays ok), then tap. When I removed my hub from the rotors that is all i had to do.
