Answer
It would appear that whoever is installing the internal components is getting the pinion bearing tightened to tight.

Once you get the axle housing overheated due to TIGHT bearings, The axle tubes and housing are HISTORY.

Going by the instructions in many cases is a major mistake. EXPERIENCE and a knack for feeling the tightness and backlash is what you depend on.
