front and rear diff lube and t-case

[Justin Fleming]

I have an 86k5 blazer from what I read

80/90 gear lube for the front and rear diff

t-fluid for the transfer case

Is t-fluid for the transfer case correct???? I have some 85 quaker state gear lube that I was wondering if i could use that to top off the diffs??


thanks

if you have the np208 t-case atf is the correct lube. I run 85w-140 in my diff's, but thats mainly cause both are a little leaky, and it leaks slower with thicker oil.

that's what my 87 takes. tranny fluid.
