From the manuals.........

ZF is Dexron Mercon 3........ plain or synthetic.

1993 Rear axles used synthetic from the factory......

Approximate Lubricant Capacity (In-Vehicle Repair)(a) (b)
Vehicle F-250, F-350 Regular & Chassis CAB, F-250/350 H.D.

Axle 10.25-Inch Ring Gear

U.S. Pints 6.5(c) (d)

Imperial Pints 5.4

Liters 3.0

(a) - Ford design conventional axles use Rear Axle Lubricant XY-90-QL or -KL (ESP-M2C154-A) or equivalent.
(b) - Service refill capacities are determined by filling the axle with the specified lubricant to the bottom of the filler hole with the vehicle in running position.
(c) - Plus 8 oz. (U.S. measure) additive friction modifier, C8AZ-19B546-A (EST-M2C118-A) or equivalent for limited-slip applications.
(d) - Rear axle lube quantities must be replaced every 100,000 miles (160 000 km) or if the axle has been submerged in water. Otherwise, the lube should not be checked or changed unless a leak is suspected or repair required.
Note: 6.5 pints of lubricant is the fill specification when the axle is installed in the vehicle. If the axle is out of the vehicle, fill with 7.5 pints of specified lubricant.

Front TTB axles are DANA 50.........

Use axle lubricant F1TZ-19580-A (WSL-M2C191-A) or equivilent..... 1.8 Litres

use atf in the zf5 gear oil is no good for it. when i first got my truck there was gear oil in it and it shifted like crap. zf calls for full synthetic atf 3.4 qts for heavy duty use. if you have the
smf conversion there are people that have overfilled with ATF to quite the rollover down or you can switch to 30wt ATF.
