The 44,000 pound axle is a hybrid axle.
It has the larger beam size (52,000 pd and up axle) of 3 inches around.
But uses smaller hub and brakes of the 35,000 pound axles (tube size less than three inches)
The brakes are 10inchs for the 44,000 pound axle and down.
the 52,000 pound and up brakes are 12 inches.
So... the spindle, hub and brakes goes to the 35,000.
The beam, goes to the 52,000.
