GMC Sierra 1500 2014 rear differential oil change (FAST AND EASY)

This is how i change my rear diff oil on my GMC sierra 2014 1500. Using a vacuum pump with my air compressor. Doing this every two years or around 35,000 km will be enough. Using 75W-90 full synthetic,GM is recommending 75W-85 but it is way too expensive for what it is... The less expensive is 30 dollars a quart here in canada. Can 75W-90 Replace 75W-85 API GL-5 Gear Oil? A reader asks: I’ve got a 2012 Cadillac Escalade that calls for a 75W-85 API GL-5 gear oil in the rear differential. AMSOIL’ s application guide suggests Severe Gear 75W-90. Is this correct? Can I safely replace 75W-85 with 75W-90? Our answer: Yes, 75W-85 gear oil can most definitely be replaced by 75W-90. In fact, we know that some GM dealers will use 75W-90 gear lube in applications where Chevrolet/Buick/GMC/Cadillac suggests 75W-85.
