Dana 44 quick question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Im pulling apart my Dana 44 front axel from my 72 chevy 3/4 ton. is the rotor and hub one piece? or two? can i replace the inner axel seals without pulling all the gears out? Thanks

Also, is there any diference in piston size between 72 and 73 calipers?

Yes, the rotor and Hub are one unit.
In order to get the inner axel seals out you have to remove the carrier inside the pumkin, so axels and everything need to come out. This will not mess up your gear alignment because the alignment shims are squeezed onto the diff by the bearings. Once you remove the diff/carrier you can pop out the seals. Use a long broom handel or something solid that you can push into the axel housing from the wheel side to contact the seal, then tap it out.
Clean and reassemble.

I think the calipers are the same 1/2ton & 3/4ton for all D44 but I am guessing on that one.

the hub and rotor have to be removed from the spindle in one piece but they are really two seperate pieces-#1 hub, #2 rotor and are held together as a unit by the "pound in" wheel studs.

True, I guess I was comparing that to the newer types that are two piece when you pullum off the spindel

Thanks guys. How do I get the rotor off of the hub? press it off? hammer out the studs?

Could someone send me a picture of dana 44 shock mounts? Both of mine are broken off and i need to fabricate some new ones. or is there some where i can buy replacment ones? thanks again

Never realy needed to do that but I would guess a shop press would be easier than trying to hammer them out.
