Applications

Tech Note 1: Shaft Specs
The length of QU40575 from the center of the u-joint hole to the end is 10-1/16". The spline size is 1-1/4" x 19 spline.

Tech Note 2: Matching Parts
Matching Parts for QU40575 Axle Shaft are:
QU40424 Factory Replacement Axle Universal Joint
QU40025 Spindle Bushing
QU40032 Axle Shaft Snap Ring

Tech Note 3: U-Joints
QU40575 uses solid cross, external snap ring universal joints without seals that are designed to be bathed in lubricant from the closed knuckle balls. By today's standards, the QU40424 u-joints are undersized for 3/4 ton models, but given the lighter vehicle weights and modestly powered engines of the early 1960's to mid 1970's, the joint size was adequate.The solid cross gives it a little extra strength, but these original equipment u-joints are expensive. I do not like to run greaseable u-joints in these axles, but you can use our QU40731 u-joints if you remove the seals and are willing to accept a little loss of strength. Our super strong Torque King® TK40719 cold-forged universal joint CAN NOT be used unless you grind some meat off the axle shaft yokes to gain clearance for installing the cross. Since the axle shafts are not all that strong anyway, grinding is obviously not something most people would want to do.
