I know there is some one out there that might be able help with the Companion Flange Press. Do all the Dana have that type Flange? Then I should be able to maybe rent one. OR make one . Any Idea's on my little bump in the road or should i say in my rear. Thanks George

 

What the heck are you talking about?????

 

The companion flange (Ford basic part number 4851) will be found between the driveshafts rear u-joint and the rear axle.

It's splined on one end to slip onto the rear axle's pinion gear. On t'other end, the rear u-joint attaches to it, then to the driveshaft.

Every Ford vehicle with RWD and an open driveline (no torque tube) has one.

But, I've never heard of a companion flange press. Why someone would need a press to install a companion flange, I dunno.

Look here to see myriad examples of the puppy: 1948/56 Ford Truck Parts Catalog / Volume II = Illustrations, pages 100-109.

8C-4851 .. Companion Flange: 1948/52 F1 & 1953/56 F100.

 

I yet to take the flange out i was looking in the manual and it said to use a companion Flange press to re install. Well I have always considered this a yoke with a pinon seal behind.I need to change the seal and looked at the manual about the rear end break down and saw the name companion Flange. I really dont think it is a big deal to change but when I saw that companion flange press got a question in my mind. Thanks for your help.

Some peeps call it a yoke, FoMoCo calls it a companion flange.

 

I have never heard of needing a press to push it on, at least on used parts. My son has done his Dana 44 axles on his Jeep several times and not needed one.

 

If you are just replacing the seal, mark the pinion and nut with a chisel, reasemble till they match. if you are installing a new pinion, bearings and sleeve, then you will have to crush the new sleeve and set the pinion preload.

 

I think you're thinking of a 9"; D-44's use spacer shims to set bearing preload. No sleeves.

Edit: I guess some very-late model D44's use crush sleeves, like 2007-up. Not ours, tho.

 

I replaced that seal not to long ago on my dana 44, no big deal and no press or puller needed.
