The waggy d44 uses lighter axletubes than a full-width d44 you would find in a truck, but they're still heavier than a d30 or a Rubi d44.
I run a Waggy front d44 and I've had enough of the low pinion. I've got a HP44 in the garage from a fullsize Ford truck, a local 4x4 shop has quoted me $300 to narrow it to Waggy width. I will then build it with my Waggy shafts and highsteer knuckles, everything that is on my current axle.
$300 isn't bad to upgrade from a LP to a HP and get a stronger housing.
