Put Some BEEF In Your Birfields

First of all, secure the vehicle by placing it in gear, applying the Emergency brake and chocking the wheels. Break loose the lugnuts from a wheel and then jack it up just enough to clear the ground. Place your jackstand under the axle and lower the jack, but leave it in place for safety reasons.

Remove the wheel and begin to tear down hub.

Remove the disc brake caliper from the disc using the 17mm socket on the two bolts on the back of the caliper. Carefully move the caliper back and try to place it on the leaf spring. You might have to use some wire to tie it out of the way. Do not allow it hang from the brake line, thus preventing a kink in the line. Using the 10mm socket, remove the locking hub bolts and the snap ring at the end of the axle.

Next, bend the retaining ring tabs back so you will be able to remove the hub nut, the retaining ring and another 2 1/8" hub nut.

You should now be able to remove the disc from the axle housing. Be careful, because the wheel bearings will fall out upon removal, this might be a good time to clean and inspect them for replacement.
Newfield
Remove the plate from behind the Disc that holds the Birfields in with the 15mm socket.

Carefully remove the Birfield by rotating it to where the flat sides match and the Birfield releases from the knuckle. Be careful removing the axle shaft, as to not damage the axle seal inside the housing.

Using the piece of pipe, place the axle shaft inside and on top of a block of wood. Raise the pipe with the Birfield placed on top and sharply rap it on the ground, vertically. This will release the axle shaft from the Birfield. Place the old Birfield in a bag, keeping the grease on it, and it's now a spare or garage sale material.
