Does anyone know off hand how many quarts I would need for front and back gears for a 98 k2500 Suburban?

Front axle:
3.5 or 3.9 pints

Rear axle:
8½ and 85/8 Inch Ring Gear = 2.1 qts.
9½ Inch Ring Gear = 2.7 qts.
10½ Inch Ring Gear = 3.25 qts.
11 Inch Ring Gear = 4.2 qts.


FYI: Gear oil for both axles = SAE 80W 90 GL5 rating.
