Rear differential confusion- and how much and what type of oil?
I'm so confused.
The manual says 75W-90 UNLESS its a Dana 60. 70, 0r 80. How can you tell?
Dodge also told me I need 4.5 Quarts. 4.5 quarts of gear oil??? wtf?
Autozone says there is no LSD on 9.25 rear axles. For 9 1/4 they said its 2.5 PINTS. Well I have my build sheet and it says:
9.25 LD Rar Axle, 3.55 Rear Axle Ratio, Anti-Spin Differential Rear Axle
Does that mean I don't really have 9 1/4, I don't really have LSD, or I have one of those other Dana rear ends?
Either way, one of the three of us is wrong, so Help is appreciated!
Thanks!

all 1500's have the chrysler 9.25 (9-1/4).
anti-spin is the same as limited slip. you have it. which means you need the little 8 oz bottle of friction modifier, available at any parts store.
any multi-grade gear oil is fine 80w90, 85w90, or the expensive 75w140. it doesn't really matter.
you need 2.5 pints, which is 1.25 qts, so you need to buy 2 qts.
use black rtv as a gasket. orange looks silly.
there. confusion solved.
