what type of diff. fluid in a 87 blazer 10 bolt open diff. with 3.73 gears?
i use 80w 90 gear oil
works well i guess, but the stuff reeks when you go to put newer stuff in
Same as the rest, 80w90... /forums/images/graemlins/k5.gif
I rather like the smell, Sometimes I imagine it would be useful as a good cologne... /forums/images/graemlins/rotfl.gif /forums/images/graemlins/rotfl.gif Good thing I'm married already! /forums/images/graemlins/thumb.gif
