Diff quick wearing,why?
Just installed the "superior axle" 5.13 ring and pinion. Done 30miles and found huge shavings when Checking for oil levels. Everything was done as per book like backlash , pinion depth, ring gear markings was perfect as well. My previous one lasted 200miles and started to make a loud noise. Where did I go wrong/ or what am I doing wrong? I used 75w90 oil. Drove in town not more then 60mile and not longer then 7 miles at a time . Can anyone help?

The shavings are from the ring and pinion gears. Looks like they eating each other. The surface of the ring gear is not smooth. Although the front is fine and I did engage into 4wd as much as I could for the first 30miles.

Very doubtful. This sounds more like the gears were installed incorrectly. Without having specs to your install (pinion depth, backlash, bearing preload etc) it's impossible to know exactly what has caused the problem.

i did the same with the front diff.
now after 70km of driving in town not exceeding 15 km at a time over the weekend. On monday checked for the oil levels and found huge fillings in the rear diff but none on the front. ( i did engage in 4wd from time to time).
what confuses me is if my install was incorrect the front diff should also be grinding, but in this case the front diff is perfect with the teeth showing perfect polish and the rear pitting.
is there any manuals that i use to correct this instal for my third attempt.
in the meantime i will try CALTEX 85w140 oil and try run the gears and hopefully they set in until my third set arrives.
any help will be appreciated.
