recently found a couple of 29 trucks....one had the usual worm drive rear but the other had one ive never seen. it looked just like the car banjo rear except 3x bigger! the cantalever springs and torquetube bolted just like they should. it didnt appear to be something cobbled in from another vehicle. it also wasnt the clamshell type from the later trucks. did i find some rare oddity or just something that doesnt belong ?
 
There was a large spiral-bevel gear type banjo rear used in the trucks for a short time. I don't know much about it. If you look at an era Ford Parts Price List book, you can see parts for this truck rear.

I think there were also 28-29 Canadian trucks with a banjo-type rear, and they had an open driveshaft with no torque tube. My friend has one of these trucks. It even has a different brake system that uses cables. The friend is an avid collector of AA's and he says the Canadian truck is authentic.
 
i checked the green book and there is some mention of a bevel gear axle for 28-29. must be what this is....thanks
 
Here are a couple of pictures of this bevel gear rear axle (early '29 usage I believe). The backing plates and radius rods are the same as used for the worm drive.

Some Canadian AAs had another variation as well. The one piece type diff housing with a removable rear cover.
Wooden spoke wheels were avail also.

O.K. all you truck gurus..tell me why there were so many different rear Diffs? I would think that Henry would have stuck with one style and maybe changed just the ratios.

A lot of the Canadian 29 AA s used a Timken rear end w -a removeable cover.They also had open drive shaft & cable brakes.In an old issue of Vintage Canada it stated that there was a bumper crop of Wheat that year & Ford couldnt get enough rear ends for trucks needed to haul the harvest,so they modified the chassies for the Timken rear ends,wood spoke wheels were also used.The wheels were similar to the 25-27 TT rearwheels,but with AA hubs & used all around.Most 28-29 AAs in Canada had Brantford cabs that had a lot of wood in them.
 
i have a 29 aa with one of these timkin rear axls but it has a torque drive in stead or the open tail shaft . the bango, axles and center are the same as open drive,but with torque tube.this truck has 29 disk wheels , cable brakes ,stake side style body , woden " c " cab 29 front body metal, 4 speed transmition, 5.16:1 crown wheel pinion. and is used as daily transport with my bussiness.
 
I only know a little about AA's and even less about the Canadian cousins. All very interesting, thanks!

Cable Brakes.... wow!
