Good point. I use the matching outer torque tube and shorten all of it from the pinion end. When I turn the solid shaft down to press I to the coupler I hold it in the lathe at the spot the carrier bearing rides on because the solid shaft tapers between the very front to the carrier bearing and then tapers again between the carrier bearing to the rear splines. This makes it easier to Install but when you go to respline in ths tapered area you have to remember not to cut the splines as deep as the ends because ths OD is slightly smaller. I have resplined them but prefer the inference press fit and weld it.
