Cost for A Body 8.75 Rear End

Keep in mind that 8 3/4 rears are formed, I suspect the steel is a bit more maluable than steel tubing, even the ends are formed from the same material, IIRC ford 9" only the center is formed and the ends and center are welded to tube.

My theory in how the 8 3/4 is formed...

Flat stock is formed around a round form and welded, this creates the axle tube

Next one end of the tube is split length wise and formed to be the top and bottom of the center.

Another part is made just like it.

A metal ring is stamped out of plate for the center section to bolt to.

The rear hump is stamped and formed.

The two halves, the hump and the bolt ring are jigged up and welded together.

Since the housings at this point could be any width they either made the halves the length they needed to be or made them all long enough for the widest they needed. Any way they were cut to a length.

The next step would be to form the bearing ends / flange into the tube, I assume the tube ends were heated and pressed into the flange shape.

The spring pirches welded on and the housing streightened.

The above is just my observations from the housings I have seen, the weld lines and the crimp marks on the tube from the ends being formed.

I would love to know from anyone who has first or second hand (ie dad worked in the plant)knowledge, if this is correct.
